Which of the following statements about a chemical reaction is false? Group of answer choices The phases in a chemical reaction tell us the state of the reactants and the products. An individual coefficient, with no reactant or product, in a balanced equation is meaningless. The subscripts in a balanced equation tell us the number of atoms in a molecule.

Option B

Explanation:

Let us go through each of the options individually.

option A.

he phases in a chemical reaction tell us the state of the reactants and the products.

This is true because phases representations such as s, l , g and q tells us the state of the reactants if they are in the solid or liquid or gaseous or aqueous state of matter respectively. So this is not our answer.

option B

An individual coefficient, with no reactant or product, in a balanced equation is meaningless.

This option is correct, because in every reaction, there must be the reactant and product present.

option C

The subscripts in a balanced equation tell us the number of atoms in a molecule.

This is correct. Consider the equation below;

2H₂ + O₂ --> 2H₂O

In the reactant phase, the subscripts tells us that we have just two atoms of oxygen present.

b is the correct answer
