Two chemicals in the liquid phase are mixed together in the same container. What change could indicate that the liquids are chemically reacting?

the temperature of the container stays the same

the liquids mix evenly

the temperature of the container rises

the liquids form two layers, like oil on water

if the temperature of the container rises, it could show that an exothermic reaction is taking place in the container. The other options don't really give any information away that would indicate that chemical reaction is happening.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
