Answer 1

The correct response is: The flame from the burner provides the energy to perform the reaction. The reaction is exothermic.

In this context, the flame provides the necessary activation energy to initiate the combustion of propane. Once the reaction begins, it releases more energy than is consumed, making it exothermic.
