Explanation / Answer

Ans28 Nuclear fuel is a substance that is used in nuclear power plants to produce heat to power the turbines. Heat is created when nuclear fuel undergoes nuclear fission. The nuclear fuels which are capable of nuclear fission contain heavy fissile elements such as uranium-235 or plutonium-239.

Ans29 Formula for Strontium chloride is SrCl2.
