Which of the following contains chemical energy? a.) atoms that in motion b.) the nucleus of an atom c.) a bond between two atoms d.) the electrons of an atom

Correct option is C.

Explanation: Chemical energy is the energy which is related to the chemical bonds of atoms and molecules. It is released in the chemical reaction.

Option A is related to the kinetic energy of the atom because the atom is in motion.

Option B is related to the nuclear energy of the atom as it is explaining about the nucleus of the atom.

Option C is related to the chemical energy of the molecule as there is the formation of a bond between two atoms.

Option D is related to the kinetic energy of the atom as we know that the electrons are in constant motion.

Measuring how quickly a reactant disappears is one way to measure the rate of the reaction. It is because the rate of reaction for product formation and reactants forming is the same. It came to a point where their reaction attains equilibrium.
