The substances that are used up in a chemical reaction (starting material) are the reactants and the new substances formed are called the products. 

Reactants are written on the L.H.S. of the arrow. Products are written on the R.H.S. of the arrow.

For example,

  2H2 + O2  →  2H2O

  Reactant      Product
