(A) The chemical formula is $K_{2}C_{2}O_{4}$.Let the oxidation number of $C$ be $x$.The oxidation number of $K$ is $+1$ and $O$ is $-2$.Sum of oxidation numbers in a neutral molecule is $0$.$(2 	imes (+1)) + (2 	imes x) + (4 	imes (-2)) = 0$$2 + 2x - 8 = 0$$2x - 6 = 0$$2x = 6$$x = +3$Therefore,the oxidation number of $C$ is $+3$.
