New substances formed during a chemical reaction are indicated- a. on the left side of the equation and are called products b. on the right side of the equation and are called products c. on the left side of the equation and are called reactants d. on the right side of the equation and are called reactants

The left side of the equation are reactants because that's what reacts to get the porduct and on the left side are products because that's what you get think of it as a multiplication question numbers at the left side are what your multi ping to get a product and both sides have to be equal remember that when you start balancing chemical equations :) hope this helps
