Question

what is the major source of energy of dissociation reaction class 10 chapter 1 science​

Answer 1

Answer:

Heat energy

Explanation:

Heat light and electricity is required to perform the reaction. The least and most common is energy so I guess it should be the major source

Answer 2

The major source of energy of a dissociation reaction is bond or the bond energy.

• A dissociation reaction is a chemical reaction in which the compounds are broken into two or more elements.
• If there is a chemical reaction, bonds break in the reactants, while new bonds form in the substance. Energy must be consumed for the bonds to dissolve.
• Energy is released when new bonds are formed. The energy required to break a bond is called the energy of bond dissociation or bond dissociation.
