Answer 1

Caron dioxide

In the laboratory, CO₂ can be prepared by the action of dilute hydrochloric acid on calcium carbonate. The reaction involved is as follows:

`CaCO_3 + 2HCl_(aq) -> CaCl_(2(aq)) + CO_(2(g)) + H_2O_(l)`

CO₂ is commercially prepared by heating limestone. The reaction involved is as follows:

Caron monoxide

In the laboratory, CO is prepared by the dehydration of formic acid with conc. H₂SO₄, at 373 K. The reaction involved is as follows:

CO is commercially prepared by passing steam over hot coke. The reaction involved is as follows:
