Give one method for industrial preparation and one for laboratory preparation of $CO$ and $CO_{2}$ each.

(N/A) Carbon monoxide $(CO)$:
- Industrial preparation: $CO$ is prepared by passing steam over hot coke at high temperatures (Water gas production).
$C_{(s)} + H_{2}O_{(g)} \xrightarrow{1273 \ K} CO_{(g)} + H_{2(g)}$
- Laboratory preparation: $CO$ is prepared by the dehydration of formic acid $(HCOOH)$ with concentrated $H_{2}SO_{4}$ at $373 \ K$.
$HCOOH \xrightarrow{conc. H_{2}SO_{4}} CO_{(g)} + H_{2}O_{(l)}$
Carbon dioxide $(CO_{2})$:
- Industrial preparation: $CO_{2}$ is prepared by the complete combustion of carbon or carbonaceous fuels.
$C_{(s)} + O_{2(g)} \xrightarrow{\Delta} CO_{2(g)}$
- Laboratory preparation: $CO_{2}$ is prepared by the action of dilute hydrochloric acid on calcium carbonate $(CaCO_{3})$.
$CaCO_{3(s)} + 2 HCl_{(aq)} \rightarrow CaCl_{2(aq)} + H_{2}O_{(l)} + CO_{2(g)}$
