Which statement is true? A. In an exothermic reaction, the energy of the products is the same as the energy of the reactants.

B. In an endothermic reaction, the energy of the products is the same as the energy of the reactants.

C. In an endothermic reaction, the energy of the products is greater than the energy of the reactants.

D. In an exothermic reaction, the energy of the products is greater than the energy of the reactants.

Exothermic reaction is where there is release of energy during a reaction

The enthalpy of exothermic reaction is negative

The relation between energy of products, reactants and enthalpy of reaction is

Enthalpy of reaction =  sum of enthalpy of formation of products - sum of enthalpy of formation of reactants .

As enthalpy of reaction is negative, it means the enthalpy of products is less than the enthalpy of reactants  so answer is :

In an exothermic reaction the energy of the product is less than the energy of the reactants.

C.

An endothermic reaction is a reaction that absorbs heat from the surroundings. That means that the energy of the system must increase. Therefore, the answer must be C as the products should have higher energy than the reactants.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
