Give one method for industrial preparation and one for laboratory preparation of CO and CO_2 each. |
|
Answer» Solution :Carbon monoxide (CO): CO is commercially prepared by passing steam over hot coke. The reaction involved is as follows: `2C_((s)) + O_2 underset"COMBUSTION"overset"Incomplete"to 2CO_((g))` In the laboratory, CO is prepared by the dehydration of formic ACID with conc. `H_2 SO_4` at 373 K. The reaction involved is as follows: `underset"Formic acid"(HCOOH) overset(H_2SO_4) toCO+ H_2O` Carbon dioxide `(CO_2)`: In the laboratory, `CO_2` can be prepared by the action of dilute hydrochloric acid on calcium carbonate. The reaction involved is as follows: `CaCO_3 + 2HCl to CaCl_2 + CO_2 + H_2O` `CO_2` is commercially prepared by heating limestone. The reaction involved is as follows : `C_((s)) + O_(2(g)) underset"combustion"overset"COMPLETE"to CO_(2(g))` |
