Chemical Reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
Reactant is a substance participating in a chemical reaction, especially a directly reacting substance present at the initiation of the reaction.
A word equation is an equation where only the words of the products and reactants are given. It is used to describe chemical reactions using words.
A skeletal equation is a chemical equation that is not balanced, with an unequal number of atoms on each side of the reaction.
A chemical equation is the symbolic representation of a chemical reaction wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.
A Coefficient is the number that normally appears at the beginning of a term in a chemical equation. It indicates the number of molecules or atoms that were involved in the chemical reaction.
1. H2 + Br2 -----> 2HBr
2. Potassium Chlorate ----> Potassium Chloride + Oxygen = KClO3 ------> KCl + O2

KClO3 ------> KCl + O2

Balanced = 2KClO3 ------> 2KCl + 3O2
3. FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl
4. Zn (s) + H2SO4 (aq) = ZnSO4 (aq) + H2 (g)
5. CuS + HNO3 -> CuSO4 + H2O + N2O

CuS + 2 HNO3 -> CuSO4 + H2O + N2O
