PLEASE HELP :(( What happens to the potential energy of the molecules in a reaction?
A. The reactants only lose potential energy when forming products.
B. The potential energy of the molecules does not change in a
reaction.
C. The potential energy of the molecules changes during a reaction.
D. The potential energy of the products is equal to that of the
reactants.

here u go its C and then reason is below :)

Explanation:

What happens to the potential energy of the molecules in a reaction?

In an exothermic chemical reaction, potential energy is the source of energy. During an exothermic reaction bonds break and new bonds form and protons and electrons go from a structure of higher potential energy to lower potential energy. During this change, potential energy is converted to kinetic energy, which is the heat released in reactions.

C

Explanation:

in most reaction the potential energy is released as heat

the maximum mass of nh3 is nh3 in grams

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
