Question

4.Given the law of conservation of energy, what best explains why heat may be absorbed during a chemical reaction?

A. The energy of the reactants is less than the energy of the products.

B. Chemical reactions absorb as much energy from the surroundings as they release.

C. The products of a chemical reaction have a higher temperature than the reactants.

D. Chemical reactions require kinetic energy because the reactants contain potential energy.

I'm not sure what the answer is but I am thinking it's B because in the law of conversion of energy is neither created nor destroyed.

Answer 1

It is A. Its called an endothermic process. Most reactions (maybe all) either absorb or release heat.
