(B) For $CaC_2$: The oxidation state of $Ca$ is $+2$. Let the oxidation state of $C$ be $x$. Thus,$+2 + 2x = 0$,which gives $x = -1$.For $K_2C_2O_4$: The oxidation state of $K$ is $+1$ and $O$ is $-2$. Let the oxidation state of $C$ be $x$. Thus,$2(+1) + 2x + 4(-2) = 0$,which simplifies to $2 + 2x - 8 = 0$,so $2x = 6$ or $x = +3$.Therefore,the oxidation states are $-1$ and $+3$ respectively.

What is the oxidation state of carbon in $CaC_2$ and $K_2C_2O_4$ respectively?
