Give one method for industrial preparation and one for laboratory preparation of CO and `CO_(2)` each.

Explanation

Carbon monoxide:Industrial method for preparation:
`2C_((S))+O_(2(g))overset("limited air")to2CO_((g))`
Laboratory method of preparation:
`underset("Carbon dioxide")underset("Formic acid")(HCOOH)overset("H_(2)SO_(4))toCO+H_(2)O`
Industrial method of preparation:
`C_((S))+O_(2(g))overset("Excess air")toCO_(2(g))`
Laboratory method of preparation:
`CaCO_(3(s))+2HCl_((aq))toCaCl_(2(aq))+CO_(2uarr(g))+H_(2)O_((l))`
