Wax melts when it is heated. Which most likely describes what is true of the result of this reaction? A. The bonding of the atoms is not the same before and after the change.
B. The wax has the same density before and after the change.
C. The same amount of wax exists before and after the change.
D. The wax cannot be changed back into a solid.

C.The same amount of wax exists before and after the change.

Explanation:

This is because it is a physical change

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
