Question

Why does matter appear to be conserved in chemical reactions but not in nuclear

Answer 1

The law of conservation of mass-energy applies only to nuclear reactions

Explanation:

In nuclear reaction the law of conservation of mass-energy applies. For chemical reactions, only the law of conservation of mass is known to be correct.

• Nuclear reactions occurs in the nucleus of an atom. The mass of an atom is concentrated in the nucleus of atom.
• The nucleus is made up of protons and neutrons.
• During nuclear reaction, the nucleus of an atom changes considerably.
• The change in the nucleus is expressed in form of a mass-energy relationship.
• In nuclear reaction, mass is converted into energy using the equation E=mc².
• Therefore, mass and energy is conserved in nuclear reactions.
