The number of atoms of each element on the reactant side of the equation must equal the number of atoms of each element on the product side of the equation.b. Subscripts in a formula may be changed so that the equation is balanced.c. The coefficients for the reactants and products may be changed to balance the equation.d. The law of conservation of matter must be obeyed.

Answer 1

b. Subscripts in a formula may be changed so that the equation is balanced.

Step-by-step explanation:

The statement b is not correct, because only the coefficients may be changed to balance the equation. If we change the subscript in a formula, we will change the compound.
