Chemical property

A chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected for its chemical properties to be investigated.

Chemical properties can be contrasted with physical properties, which can be discerned without changing the substance's structure. However, for many properties within the scope of physical chemistry, and other disciplines at the border of chemistry and physics, the distinction may be a matter of researcher's perspective. Material properties, both physical and chemical, can be viewed as supervenient; i.e., secondary to the underlying reality. Several layers of superveniency are possible.

Chemical properties can be used for building chemical classifications.

Examples of chemical properties

For example hydrogen has the potential to ignite and explode given the right conditions. This is a chemical property.

Metals in general do they have chemical properties of reaction with an acid. Zinc reacts with hydrochloric acid to produce hydrogen gas. This is a chemical property.

Answers:#3.

Question:2.list the kinds of chemical reaction. 3.what are the products , when wax burns? 4.How can water be decomposed into its elements, hydrogen and oxygen? 5. How can silver be prevented from tarnishing? 6. Identify these properties of matter as chemical (C) or physical(P). a. magnetic, b. rusting, c. shape, d. oxidizing, e. density, f. electroplating, g. color, h. burning, i. weight, j. reaction with acid, j. hardness

Answers:1. chemical properties are those that deal with the molecular structure of matter (e.g. corrosivity, reactivity of substance for chemical change). on the other hand physical properties (e.g. weight) deal with the physical characterstics of matter. 2. a. double displacement b. single displacement c. decomposition d. combustion e. redox reaction f. complexation 3. CO2 and H2O 4. electrolysis 5. metal protection (coating the metal through electroplating or have a sacrifical metal) 6. a. chemical b. chemical c. physical d. chemical e. physical f. chemical g. physical or chemical h. chemical i. physical j. chemical j. physical (if hardness of water, chemical)
