In a compound, chemical energy is contained in the
a. nuclei of the atoms.
b. unbonded electrons.
c. bonds.
d. movement of the electrons.

The answer is C. bonds. Because chemical energy in compounds is stored in bonds between the molecules involved.

Energy is the ability to do work, where work is the movement of objects by force. We use energy every day, and energy comes in different forms. Chemical energy is energy stored in chemicals, such as sugar and gasoline.

Chemical energy is energy stored in chemical compounds in the form of bonds between one atom with another atom. Chemical energy is an energy produced in a chemical process. The amount of energy produced depends on the type and amount of reagents in a chemical reaction. Devices that can produce energy from chemical reactions such as batteries and batteries.

Chemical Energy Sources

chemical allergens are stored in molecular bonds and when these bonds break, heat is released or absorbed. These molecules are part of chemical compounds or fuels such as coal, oil, biomass, wood, animal waste, natural gas, food, etc. and they are all sources of chemical energy that generates heat usually through combustion. Chemical energy sources can be classified into two types, depending on whether they are naturally or artificially prepared and depending on their natural state (solid, liquid, or gas):

All of these fuels contain hydrocarbons - organic compounds containing carbon and hydrogen - various molecular weights. These hydrocarbons may be alkanes (methane, ethane, propane, etc.), alkenes (ethene, propane, etc.), cycloalkanes, aromatic hydrocarbons, and heterocyclic compounds.
