Question

Suppose you want to use a combustion chemical reaction to cook hot dogs and hamburgers. what type of reaction would you want? a an exothermic reaction that releases energy. b a reaction that destroys energy. c a reaction that creates energy. d an endothermic reaction that absorbs energy.

Answer 1

Answer : The correct answer is a) an exothermic reaction that releases energy.

Combustion reaction is generally referred as burning or when hydrocarbon reaction with oxygen to produce carbon dioxide and water . Combustion reaction releases energy. Example :

CH₄ + O₂ → CO₂ + H₂O + Energy or heat .

The reaction which releases energy or heat are known as Exothermic reactions .

Since it says hot dogs and hamburgers are cooked means they are undergoing combustion chemical reaction and so they are exothermic reactions. So option a) an exothermic reaction which releases energy is correct .

Answer 2

D. endothermic reaction that absorbs energy
