A. products is greater than the chemical energy of the reactant.

B. reactant is greater than the chemical energy of the products.

C. reactant and the chemical energy of the products are equal.

D. cannot be determined

Answer 1

Are you sure @GrlLuv its not Delta H +137KJ

Answer 2

if its not Delta H, +heat means that the reaction is exothermic and the products have a lower energy than the reactants. The energy that the system loses is given out as heat. The surroundings warm up and temperature increases.
