Answer:
Reactants are on the left side; products are on the right side.
Explanation:
For example, when hydrogen and oxygen react to form water, the chemical equation is:
[tex]\underbrace{\hbox{2H$_{2}$ +O$_{2}$}}_{\hbox{reactants}} \longrightarrow \, \underbrace{\hbox{2H$_{2}$O}}_{\hbox{product}}[/tex]
The hydrogen and oxygen are the reactants, and water is the product.
