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

The potential energy of the molecules change during a reaction  

Explanation:

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. Also, energy is converted to kinetic energy, which is the heat released in reactions.

a. hope i'm right

explanation:

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
