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.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
