1.	For the isolation of inert gases from air, the nitrogen and oxygen present are removed by nitrogen and oxygen present are removed by passing air over heatedA. Calcium carbideB. Copper metalC. Activated charcoalD. Finely divided mixture of Pt and Pd.
Answer» Correct Answer - A Oxygen and nitrogen present in air can be removed strongly heating calcium carbide. `CaC_(2) + N_(2) overset(Delta) rarr CaCN_(2) + C` `2C + O_(2) overset(Delta) rarr 2CO`
