When oxalic acid is heated, it decomposes into carbon dioxide, carbon monoxide, and water vapor.

$H_{2} C_{2} O_{4} Δ C O_{2} (g) + CO (g) + H_{2} O (g)$

(A) (B) (C) (D)

Carbon dioxide reacts with calcium hydroxide to form calcium carbonate and water.

$C O_{2} (g) + C a (O H)_{2} \to C a C O_{3} (s) + H_{2} O (l)$

(B)

Carbon monoxide reacts with chlorine to form phosgene, which then reacts with ammonia to produce urea.

$CO + C l_{2} \to COC l_{2} 2 N H_{3}, - 2 H Cl U re a$
