Question

During a chemical reaction, the amount of energy

A) may increase or decrease depending on the type of reaction
B) increases as it is converted from one form to another
C) decreases as it is converted from one form to another
D) is constant as it is converted from one form to another

Answer 1

D is the answer. The level of matter cannot be shifted, it can only stay constant even during chemical reactions. 

Answer 2

During a chemical reaction, the amount of energy is constant as it is converted from one form to another. So the answer would be letter D. The amount of energy is just the same because it will be use in the reaction to produce by product.
