Question

Differentiate chemical reactions from nuclear.

Answer 1

Chemical reaction	Nuclear reaction
1. These reaction involve some loss, gain or overlap of outer electrons of the reactant atoms.	Nuclear reactions involve emission of Alpha, beta and gamma particles from the nucleus.
2. A chemical reaction is balanced in terms of mass only.	Nuclear reaction is balanced in terms of both mass and energy.
3. The energy changes in any chemical reaction is very much less.	The energy changes is more in Nuclear reactions.
4. The energy is expressed in tens of kilojoules per mole.	The energy involved is expressedd in MeV (Million election Volts) per individual nucleus
5. Now hew element is produced since. nucleus is unaffected.	New element/isotope may be produced during the nuclear reaction
