Chemistry in Everyday Life





We know that chemistry is a big part of our everyday life in various fields such as food, air, metabolic system of body, and medicines etc.
It is an important part of our life and this is because everything we are using is composed of different chemicals. 

Any change in our surrounding is also related to either chemical or physical change in the substances. 
The chemical changes are associated with change in the chemical composition or change in colour or odour of the substances. 
Chemical changes or chemical reactions are also associated with the formation of precipitate or colour solution.  

Physical changes involve with the change in the physical state of matter from solid to liquid or liquid to gas etc. 
The change in colour of leafs or cooking of food are also examples of chemical changes. 
The household chemicals such as mosquito repellents, drugs, and plastic materials are also chemical substances. 
All types of plastics are polymers which are chemical compounds composed of similar or different monomer units. 
These monomer units are either bonded through condensation reaction or by addition reactions. 
On the basis of these reactions, polymers can be classified as additional and condensation polymers. 
The properties of polymers depend upon the structural units of monomer and the chemical reactions which are involved in the formation of polymer molecules.
Polymers can be both synthetic and natural such as PVC, nylon-6,6, nylon-6 are synthetic polymer but cellulose, starch, cotton are natural polymers. 

Biological molecules  such as DNA, RNA, and proteins are polymeric in nature. 
Another example of chemical which we are using in our everyday life is cleaners such as soaps, detergents etc.  
Usually soaps are Sodium or Potassium salts of fatty acids which can divide in two parts; tail part is a long hydrocarbon chain while head part is Carboxylate group which is hydrophilic in nature. 
The tail or hydrocarbon part of soap molecule is hydrophobic in nature and cannot dissolve in water but can be in dirt or oil. 
The micelles formation by soap molecules results the detachment of dirt part from the cloth surface and show the soap action. 

Let’s discuss about another chemical that is drug. They are chemical compounds which could show both positive and negative types of effect on  human beings. 
These drugs could be subdivided into various categories and one of such is the amphetamine which is basically a stimulant. 
These chemicals are found to be good for health and they help in recovery in several diseases but if taken within the safe limit or certain concentration only. 
The drug abuse is a very common issue in almost all the countries. 
Alcohol is one of best example of drug and yet another example is the tobacco abuse which is very common in India. 
It is basically the dried tendu leaves which contain the drug nicotine. 
It acts as an stimulant or relaxant after ingestion either through smoke, snuff, dipped or chewed. 

The ingestion of it can lower the blood pressure and heart rate as well. 
Up to a certain level, it can act as an stimulant but if taken at higher doses, it could imbalance the O2 level of the body and act as a relaxant or sedative. 
The longer abuse of this could cause chronic lung disease, heart diseases like stroke, addiction and many different types of cancerous growth. 
The presence of nicotine activates the brain of a living body and produces sensations of pleasure and euphoria. 
It shows instant effect on human body; therefore it could be mistaken for tons of “hits” a day and become habitual of it. 
Usually it is inhaled through smoking or even oral ingestion. Other examples of drugs are Sulphonamide, histamines etc.

Advanced Chemistry

Advanced Chemistry is a German hip hop group from Heidelberg, a scenic city in Baden-Württemberg, South Germany. Advanced Chemistry was founded in 1987 by Toni L, Linguist, Gee-One, DJ Mike MD (Mike Dippon) and MC Torch. Each member of the group holds German citizenshhip, and Toni L, Linguist, and Torch are of Italian, Ghanaian, and Haitian backgrounds, respectively.

Influenced by North American socially conscious rap and the Native tongues movement, Advanced Chemistry is regarded as one of the main pioneers in German hip hop. They were one of the first groups to rap in German (although their name is in English). Furthermore, their songs tackled controversial social and political issues, distinguishing them from early German hip hop group "Die Fantastischen Vier" (The Fantastic Four), which had a more light-hearted, playful, party image.

The rivalry between Advanced Chemistry and Die Fantastischen Vier has served to highlight a dichotomy in the routes that hip hop has taken in becoming a part of the German soundscape. While Die Fantastischen Vier may be said to view hip hop primarily as an esthetic art form, Advanced Chemistry understand hip hop as being inextricably linked to the social and political circumstances under which it is created. For Advanced Chemistry, hip hop is a “vehicle of general human emancipation,�. In their undertaking of social and political issues, the band introduced the term "Afro-German" in to the context of German hip hop, and the theme of race is highlighted in much of their music.

With the release of the single “Fremd im eigenen Land�, Advanced Chemistry separated itself from the rest of the rap being produced in Germany. This single was the first of its kind to go beyond simply imitating US rap and addressed the current issues of the time. Fremd im eigenen Land which translates to “foreign in my own country� dealt with the widespread racism that non-white German citizens faced. This change from simple imitation to political commentary was the start of German identification with rap. The sound of “Fremd im eigenen Land� was influenced by the 'wall of noise' created by Public Enemy's producers, The Bomb Squad.

After the reunification of Germany, an abundance of anti-immigrant sentiment emerged, as well as attacks on the homes of refugees in the early 90's. Advanced Chemistry came to prominence in the wake of these actions because of their pro-multicultural society stance in their music. Advanced Chemistry's attitudes revolve around their attempts to create a distinct "Germanness" in hip hop, as opposed to imitating American hip hop as other groups had done. Torch has said, "What the Americans do is exotic for us because we don't live like they do. What they do seems to be more interesting and newer. But not for me. For me it's more exciting to experience my fellow Germans in new contexts...For me, it's interesting to see what the kids try to do that's different from what I know." Advanced Chemistry were the first to use the term "Afro-German" in a hip hop context. This was part of the pro-immigrant political message they sent via their music.

While Advanced Chemistry's use of the German language in their rap allows them to make claims to authenticity and true German heritage, bolstering pro-immigration sentiment, their style can also be problematic for immigrant notions of any real ethnic roots. Indeed, part of the Turkish ethnic minority of Frankfurt views Advanced Chemistry's appeal to the German image as a "symbolic betrayal of the right of ethnic minorities to 'roots' or to any expression of cultural heritage." In this sense, their rap represents a complex social discourse internal to the German soundscape in which they attempt to negotiate immigrant assimilation into a xenophobic German culture with the maintenance of their own separate cultural traditions. It is quite possibly the feelings of alienation from the pure-blooded German demographic that drive Advanced Chemistry to attack nationalistic ideologies by asserting their "Germanness" as a group composed primarily of ethnic others. The response to this pseudo-German authenticity can be seen in what Andy Bennett refers to as "alternative forms of local hip hop culture which actively seek to rediscover and, in many cases, reconstruct notions of identity tied to cultural roots." These alternative local hip hop cultures include Oriental hip hop, the members of which cling to their Turkish heritage and are confused by Advanced Chemistry's elicitation of a German identity politics to which they technically do not belong. This cultural binary illustrates that rap has taken different routes in Germany and that, even among an already isolated immigrant population, there is still disunity and, especially, disagreement on the relative importance of assimilation versus cultural defiance. According to German hip hop enthusiast 9@home, Advanced Chemistry is part of a "hip-hop movement [which] took a clear stance for the minorities and against the [marginalization] of immigrants who...might be German on paper, but not in real life," which speaks to the group's hope of actually being recognized as German citizens and not foreigners, despite their various other ethnic and cultural ties.

Market conditions for rap

One of the first issues that confronts us when we move outside the English-speaking market for recorded music is to establish whether or not the discrete musical genres we know from that market are fully congruent with similar divisions in other pop worlds. This is important in two ways. First, although no single country comes close to matching the amounts spent on recorded music in the United States, these markets are nonetheless economically significant. Germany, for instance, is the largest single market in western Europe, with estimated annual sales of U.S. $3.74 billion in 1996. This represents around 30 percent of reported U.S. sales and makes Germany the third biggest music market in the world.

Advanced Chemistry frequently rapped about their lives and experiences as children of immigrants, exposing the marginalization experienced by most ethnic minorities in Germany, and the feelings of frustration and resentment that being denied a German identity can cause. The song "Fremd im eigenem Land" (Foreign in your own nation) was released by Advanced Chemistry in November 1992. The single became a staple in the German hip hop scene. It made a strong statement about the status of immigrants throughout Germany, as the group was composed of multi-national and multi-racial members. The video shows several members brandishing their German passports as a demonstration of their German citizenship to skeptical and unaccepting 'ethnic' Germans.

This idea of national identity is important, as many rap artists in Germany have been of foreign origin. These so-called Gastarbeiter (guest workers) children saw breakdance

Life skills

Life skills are a set of human skills acquired via teaching or direct experience that are used to handle problems and questions commonly encountered in daily human life.

Definition

The World Health Organization defines life skills as "abilities for adaptive and positive behaviour that enable individuals to deal effectively with the demands and challenges of everyday life." In primary and secondary education, life skills may refer to a skill set that accommodates more specific needs of modern industrialized life; examples include money management, food preparation, hygiene, basic literacy and numeracy, and organizational skills. Life skills are sometimes, but not always, distinguished from occupational skills.

Learning to know: Cognitive abilities

Decision making / problem solving skills

  • Information gathering skills
  • Evaluating future consequences of present actions for self and others
  • Determining alternative solutions to problems
  • Analysis skills regarding the influence of values and attitudes of self and others on motivation

Still life

A still life(plural still lifes) is a work of art depicting mostlyinanimate subject matter, typically commonplace objects which may be either natural (food, flowers, plants, rocks, or shells) or man-made (drinking glasses, books, vases, jewelry, coins, pipes, and so on). With origins in the Middle Ages and Ancient Greek/Roman art, still life paintings give the artist more leeway in the arrangement of design elements within a composition than do paintings of other types of subjects such as landscape or portraiture. Still life paintings, particularly before 1700, often contained religious and allegorical symbolism relating to the objects depicted. Some modern still life breaks the two-dimensional barrier and employs three-dimensional mixed media, and uses found objects, photography, computer graphics, as well as video and sound.

History

Ancient antecedents

Still life paintings often adorn the interior of ancient Egyptian tombs. It was believed that food objects and other items depicted there would, in the afterlife, become real and available for use by the deceased. Ancient Greek vase paintings also demonstrate great skill in depicting everyday objects and animals. Similar still life, more simply decorative in intent, but with realistic perspective, have also been found in the Roman wall paintings and floor mosaics unearthed at Pompeii, Herculaneum and the Villa Boscoreale, including the later familiar motif of a glass bowl of fruit. Decorative mosaics termed “emblema�, found in the homes of rich Romans, demonstrated the range of food enjoyed by the upper classes, and also functioned as signs of hospitality and as celebrations of the seasons and of life. By the 16th century, food and flowers would again appear as symbols of the seasons and of the five senses. Also starting in Roman times is the tradition of the use of the skull in paintings as a symbol of mortality and earthly remains, often with the accompanying phrase Omnia mors aequat (Death makes all equal). These vanitas images have been re-interpreted through the last 400 years of art history, starting with Dutch painters around 1600.

The popular appreciation of the realism of still life painting is related in the ancient Greek legend of Zeuxis and Parrhasius, who are said to have once competed to create the most life-like objects, history’s earliest descriptions of trompe-l'œil painting. As Pliny the Elder recorded in ancient Roman times, Greek artists centuries earlier were already advanced in the arts of portrait painting and still life. He singled out Peiraikos, “whose artistry is surpassed by only a very few...He painted barbershops and shoemakers’ stalls, donkeys, vegetables, and such, and for that reason came to be called the ‘painter of vulgar subjects’; yet these works are altogether delightful, and they were sold at higher prices than the greatest [paintings] of many other artists.�

Middle Ages and Renaissance

By 1300, starting with Giotto and his pupils, still life painting was revived in the form of fictional niches on religious wall paintings which depicted everyday objects. Through the Middle Ages and the Renaissance, still life in Western art remained primarily an adjunct to Christian religious subjects, and convened religious and allegorical meaning. This was particularly true in the work of Northern European artists, whose fascination with highly detailed optical realism and symbolism led them to lavish great attention on their paintings' overall message. Painters like Jan van Eyck often used still life elements as part of an iconographic program.

The development of oil painting technique by Jan van Eyck and other Northern European artists made it possible to paint everyday objects in this hyper-realistic fashion, owing to the slow drying, mixing, and layering qualities of oil colors. Among the first to break free of religious meaning were Leonardo da Vinci, who created watercolor studies of fruit (around 1495) as part of his restless examination of nature, and Albrecht Dürer who also made precise drawings of flora and fauna.

Petrus Christus’ portrait of a bride and groom visiting a goldsmith is a typical example of a transitional still life depicting both religious and secular content. Though mostly allegorical in message, the figures of the couple are realistic and the objects shown (coins, vessels, etc.) are accurately painted but the goldsmith is actually a depiction of St. Eligius and the objects heavily symbolic. Another similar type of painting is the family portrait combining figures with a well-set table of food, which symbolizes both the piety of the human subjects and their thanks for God’s abundance. Around this time, simple still life depictions divorced of figures (but not allegorical meaning) were beginning to be painted on the outside of shutters of private devotional paintings. Another step toward the autonomous still life was the painting of symbolic flowers in vases on the back of secular portraits around 1475. Jacopo de’ Barbari went a step further with his Still Life with Partridge, Iron Gloves, and Crossbow Arrows (1504), among the earliest signed and dated trompe-l'œil still life paintings, which contains minimal religious content.

Sixteenth century

The 16th century witnessed an explosion of interest in the natural world and the creation of lavish botanical encyclopædias recording the discoveries of the New World and Asia. It also prompted the beginning of scientific illustration and the classification of specimens. Natural objects began to be appreciated as individual objects of study apart from any religious or mythological associations. The early science of herbal remedies began at this time as well, a practical extension of this new knowledge. In addition, wealthy patrons began to underwrite the collection of animal and mineral specimens, creating extensive “curio cabinets�. These specimens served as models for painters who sought realism and novelty. Shells, insects, exotic fruits and flowers began to be collected and traded, and new plants such as the Semisonic, released on March 13, 2001. With this release, the band failed, at least in America, to capitalize on the momentum it had generated with the song "Closing Time" from their previous album, Feeling Strangely Fine. This had a softer edge than Feeling Strangely Fine and was not as popular with the fans. Its poor sales led to the band going on an unofficial hiatus. The title track was featured on the soundtrack for 40 Days and 40 Nights.

The song "One True Love" was co-written by the band's singer/guitarist, Dan Wilson, and music legend Carole King. The song "Get a Grip" is an ode to masturbation.

The special edition of the album features cover art with orange fluid in the vials instead of the blue fluid of the original. It includes two bonus tracks, "Girlfriend" and "Ordinary Life"; instead of being tacked onto the end, they appear between "Get a Grip" and "Surprise."

As of 2011, All About Chemistry remains the band's last studio album.

Answers:Culinary use ------------------- Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. In Japan it is sold as nigari ( , derived from the Japanese word for "bitter"), a white powder produced from seawater after the sodium chloride has been removed, and the water evaporated. In China it is called "lushui" ( in Chinese). Nigari or Lushui consists mostly of magnesium chloride, with some magnesium sulfate and other trace elements. It is also an ingredient in baby formula milk. Use as an anti-icer ----------------------------- A number of state highway departments throughout the United States have decreased the use of rock salt and sand on roadways and have increased the use of liquid magnesium chloride as a de-icer or anti-icer. Magnesium chloride is much less toxic to plant life surrounding highways and airports, and is less corrosive to concrete and steel (and other iron alloys) than sodium chloride. The liquid magnesium chloride is sprayed on dry pavement (tarmac) prior to precipitation or wet pavement prior to freezing temperatures in the winter months to prevent snow and ice from adhering and bonding to the roadway. The application of anti-icers is utilized in an effort to improve highway safety. Magnesium chloride is also sold in crystal form for household and business use to de-ice sidewalks and driveways. In these applications, the compound is applied after precipitation has fallen or ice has formed, instead of previously. The use of this compound seems to show an improvement in driving conditions during and after freezing precipitation yet it seems to be negatively affecting electric utilities. Two main issues have been raised regarding the anti-icer magnesium chloride as it relates to electric utilities: contamination of insulators causing tracking and arcing across them, and corrosion of steel and aluminium poles and pole hardware.

Answers:Chemical reactions are all around us. Combustion reactions help release energy to heat our homes and move our vehicles. Oxidation-reduction reactions keep the batteries in our cell phones and laptops functioning. Acid-base reactions take place when cleaning your oven or removing a clog from a drain. Acid-base reactions are also the basis for the Titrations experiment where you will measure the acidity of fruit juices. Understanding and identifying what takes place when two substances interact with one another is a vital aspect of chemistry. Chemists are able to identify unknown substances by observing how they react with a known substance. For example, we can bubble an unknown gas through a solution of limewater (Ca(OH)2 dissolved in water). If the limewater becomes cloudy (that is, a precipitate forms), we can say that the gas is probably carbon dioxide based on our knowledge that the calcium ion (Ca2+) forms an insoluble carbonate salt (CaCO3); if the limewater does not become cloudy, we can t identify the gas without further tests, but we can say that the gas is not carbon dioxide. It is through testing and deductive reasoning that the chemist operates. Evidence of a chemical reaction or change can often be observed when two different solutions are mixed together. Chemical reactions may often be detected visually by the following manifestations: the formation of a precipitate (insoluble substance), effervescence (gas bubbles), or color changes. Sometimes the precipitate does not immediately settle out, thereby causing a "cloudiness" to appear in the solution. Interpret "cloudiness" as the formation of a precipitate. Chemical reactions may occur even if there is not apparent change in the color of solution and if all products formed during the reaction are soluble. In general, the reactions in this experiment will follow this chemical equation: C1A1 + C2A2 ----> C1A2 + C2A1 where C represents the cations (ions with a positive charge) and A represents the anions (ions with a negative charge). When acids and bases are mixed, a salt and water are formed. For those reactions where a precipitate or cloudiness is observed, refer to "Empirical Rules for the Solubilities of Common Ionic Compounds" to aid you in determining which cation and anion form a precipitate when you observe this behavior in a reaction. The only reactions for which the above equation will not hold are those that generate gases. http://chemlab.truman.edu/CHEM100Labs/CHEMICAL%20REACTIONS%20IN%20EVERYDAY%20LIFE.pdf http://www.life123.com/parenting/education/chemistry/chemistry-in-everyday-life.shtml

Betty White - Life With Elizabeth - The Chemistry Set :In this episode from 1954 Alvin is trying to make hand lotion with a children's chemistry set... This is of course bound to go wrong... ________________ From Wikipedia: Life With Elizabeth was a sitcom which aired from 1953 to 1955. The show starred Betty White and Del Moore and announcer Jack Narz. The most unusual feature of Life with Elizabeth is that it was divided into three 8 to 10 minute comic shorts referred to as "incidents". Sometimes an entire incident might just consist of the two main characters talking to each other. Also unusual was the minimal theme music, which was played by a solo harpist who was partially visible on the opening title screen. Elizabeth and Alvin are a married couple who live an ordinary suburban life, but inevitably managed to get into predicaments. At the end of most predicaments, Alvin, in variable degrees of frustration, would say, "I shall leave you now, Elizabeth" and would walk out of sight. The announcer would say, "Elizabeth, aren't you ashamed?" She would slowly nod, but then, with a slightly devilish grin, would vigorously shake her head to indicate she wasn't.
