Question

If chemical reactions involve atoms disconnecting from each other and then connecting with different atoms in different ways, why do you think energy would go into or out of chemical reactions? In other words, how could energy be involved in disconnecting or connecting atoms to each other?

Answer 1

Answer:  Energy can  be involved in disconnecting or connecting atoms to each other as the energy is used to break the bonds between the atoms ,so the reaction could proceed.

Explanation: The statement can be well explained by the  Planck's quantum theory , which states -:

• In the form of small energy packets known as quanta of energy, energy is not released continuously, but discontinuously.
• The energy of each quantum is directly proportional to radiation frequency, i.e. E is directly proportional to v, where v is frequency E = hv, where h is the proportionality constant known as the constant of Planck.
• Any integer quanta will be the total energy of the radiation emitted or absorbed. Let the 'E' be the total radiation energy. So, when n is an integer, E'=nhv.

Hence, the given answer is based on the Planck's Quantum theory.
