Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation. If any chemical species are listed on both sides of the equation e.
In this reaction, A is the reactant, while B and C are products:. The number and type of atoms is the same for the products and the reactants in a balanced chemical equation. For example, the number of hydrogen and oxygen atoms is the same for the reactants H 2 and O 2 and product H 2 O. The number of each type of atom is its coefficient multiplied by its subscript or by 1 if no coefficient or subscript is listed.
So, there are 4 atoms of hydrogen on the reactant side 2 x 2 and 2 atoms of oxygen 1 x 2. There are 4 atoms of hydrogen on the product side 2 x 2 and 2 atoms of oxygen 2 x 1. Many reactions proceed in both directions to reach an equilibrium state.
