Answers:as an answer to your email: 1.. placing a 5ml dilute of hydrochloric acid into test tube, add small amount of sodium bicarbonate to a second clean dry test tube. Invert the test tube containing the sodium bicarbonate over the one with hydrochloric acid. the hydrochloric acid is a colorless solution the sodium bicarbonate is a white solid when youi mix the two the begin with a neutralization reaction, which is a variation odf a double replacement: HCl(aq) & NaHCO3 (s) --> NaCl (aq) & H2CO3 (aq) however it then does a decomposion reaction producing CO2 gas H2CO3 --> H2O (l) & CO2(g) since the Co2 is more dense than air, it will not enter the inverted test tube over the one with hydrochloric acid. 2. Repeat number 1 , except with magnesium 'this is a single replacement reaction between the silvery magnesium metal & the colorless HCl it produces colorless H2 gas bubbles & soluble MgCl2 (neither of which have colors) Mg & 2 HCl --> H2 (g) & MgCl2 (aq) these bubbles ar less dense than air & will enter the inverted test tube over the one with hydrochloric acid. which you can later ignite
Answers:Zn + 2 HCl -----> ZnCl2 + H2
Answers:Sulphuric acid is H2SO4. Other common acids are: Acidtic acid (vineger) CH3COOH Ascorbic acid (vitamin C) H2C6H6O6 Citric acid (in citrus fruit) H3C6H5O7 Hydrochloric acid (stomach acid) HCl Acetylsalicylic acid (asprin) HC9H7O4 Some common bases: Ammonia (household cleaner) NH3 Calcium hydroxide (slaked lime) Ca(OH)2 Magnesium hydroxide (an antacid) Mg(OH)2 Potassium hydroxide (soap) KOH Sodium hydroxide (drain cleaner) NaOH To be honest about figuring out chemical formulas, unless you have the real scientific name, like sodium hydroxide which you can use nomenclature to figure it out, you have to either go to google, ask here, or look it up in a textbook.
