Question

considering the role of enthalpy in choosing energy sources
many fuels, such as gasoline and diesel fuel, are hydrocarbons. hydrocarbons are molecules that contain only hydrogen and carbon. choose three of the criteria that would make a hydrocarbon a good fuel in terms of enthalpy.
the enthalpy of combustion is a large negative value.
burning hydrocarbons produces a lot of energy.

Explanation:

A good fuel should release a large amount of energy when burned. The enthalpy of combustion being a large negative value indicates an exothermic reaction that releases a significant amount of energy. Burning hydrocarbons producing a lot of energy is also a key - characteristic of a good fuel in terms of enthalpy.

Answer:

The enthalpy of combustion is a large negative value.
Burning hydrocarbons produces a lot of energy.
