Final Answer:
The object that represents an object with a lot of chemical energy is a hydrocarbon fuel, such as gasoline.
Step-by-step explanation:
Hydrocarbon fuels, like gasoline, contain a high amount of chemical energy due to the carbon-carbon and carbon-hydrogen bonds. When these bonds are broken during combustion, a large amount of energy is released. Gasoline, for example, has a high energy density of about 46.4 megajoules per kilogram. This means that a small amount of gasoline can release a significant amount of energy when burned.
Furthermore, the chemical equation for the combustion of gasoline can be used to calculate the amount of energy released. For example, the balanced chemical equation for the combustion of octane (a component of gasoline) is
. Using the standard enthalpy of formation values for each compound involved in the reaction, along with stoichiometry, one can calculate the heat released during the combustion process.
In conclusion, hydrocarbon fuels like gasoline are excellent examples of objects with a lot of chemical energy due to their high energy density and the significant amount of energy released during combustion.
