1. How are chemical properties and physical properties of matter different?

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

Answer 1

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)
