Answer 1

Answer:

The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.

Answer 2

Answer:

Chemistry is the study of the change of matter from one form to the other. These changes often occur as a result of the combination of two different types of matter. There are certain rules that govern the combination of different elements to form different compounds. These rules are, what we call, the laws of chemical combinations.
