no
It depends on the reaction. Also, only the products are produced by a chemical reaction; the reactants produce the reaction and are changed in the reaction to the products. (If you have a chemical equation, the number of distinct molecules and/or isolated element symbols on the right side of the equation will show how many distinct products are formed in the reaction.)
The reaction is: 2 Mg + O2 = 2 MgO
