Question

The students are studying the process of how controlled gasoline explosions that take place in a cars engine change the potential chemical energy into the kinetic mechanical energy that moves the car.

which statement is true about this reaction?
A..This is an exothermic reaction because energy is absorbed.

B.this an endothermic reaction because energy is absorbed.

C.this is an exothermic reaction because energy is released

D.this is an endothermic reaction because energy is released​

Answer 1

C.this is an exothermic reaction because energy is released

Step-by-step explanation:

The explosion of gasoline in a car engine is an exothermic reaction.

An exothermic reaction is one in which heat is given out to the environment. That means, heat is released during the reaction.

When gasoline undergoes controlled explosion in car engines, heat is released, hence the answer.
