In a chemical equation

a. the reactants are on the right of the yields arrow.
b. reactants and products are on both sides of the yields arrow.
c. the products are on the left of the yields arrow.
d. the reactants are on the left of the yields arrow.
e. the number of atoms of each element may differ on the two sides of the yields arrow.

Answer in explanation

Explanation:

A. This is wrong. The reactants are on the left side of the yields arrow

B. This is wrong. They can only be at one side at a time. They cannot be on both sides at the same time.

C. The products are on the right side of the yields arrow and not at the left side

D. This is correct. The reactants are on the left side of the yields arrow.

E. This is correct. We can have varying numbers of the number of atoms on both side of the yields arrow. The numbers may differ until we decide to balance the equation
