Question

What type of reaction occurs when gasoline is burned in an engine?

A. Exothermic, because energy is absorbed from the surroundings
B. Endothermic, because energy is released into the surroundings
C. Endothermic, because energy is absorbed from the surroundings
D. Exothermic, because energy is released into the surroundings

Answer 1

D

Step-by-step explanation:

The correct answer is D. Exothermic, because energy is released into the surroundings. When gasoline combusts, the chemical bonds that were holding together the molecules of the fuel and oxygen are broken, releasing energy in the form of heat and light. This energy is then used to power the engine.
