Question

In a compound, chemical energy is contained in the
A) bonds
B) movement of the electrons
C) unbonded electrons
D) nuclei of the atoms

Answer 1

A) bonds. since when one reactant reacts with other reactant there is a chemical reaction taking place so there is also a bond formation between them and the chemical energy is contained in this bond.

Answer 2

The correct answer is option A) Bonds.

Chemical energy is the potential of a chemical substance to undergo a change to convert into chemical substances, and this change comes from the chemical reaction that occurs.

In a compound, the chemical energy is contained in the bonds of the atoms. This is evident from the fact that breaking chemical bonds require energy and  forming new bonds, release energy. The more amount of energy released signified that the bond is strong.
