Which of the following happens during an endothermic chemical change?
a) heat is released.
b) net energy decreases.
c) products have a higher total potential energy than the reactants.
d) products have the same total potential energy as the reactants.

It’s C. In an endothermic reaction, energy is absorbed, thus making the products of a higher potential energy

An exothermic reaction releases energy. Think of a bomb or a fire

C) Products have a higher total potential energy than the reactants is the correct answer.

Explanation:

In the endothermic reaction, energy is absorbed from the surroundings and the products produced in the endothermic reaction have higher energy than reactants.Change in enthalpy is positive in the endothermic reaction.In endothermic reactions, heat is required so that reaction can occur.

Examples of endothermic reactions are:

Melting of ice cubes.Evaporating of liquid water.photosynthesis.

The correct answer is b
