State whether the following statement is true or false:
The chemical formulae of cupric oxide and cuprous oxide are $CuO$ and $Cu_{2}O$ respectively.
The chemical formulae of cupric oxide and cuprous oxide are $CuO$ and $Cu_{2}O$ respectively.
(TRUE) The statement is True.
In cupric oxide,copper exhibits a valency of $+2$,and oxygen exhibits a valency of $-2$. By crossing the valencies,we get $Cu_{2}O_{2}$,which simplifies to $CuO$.
In cuprous oxide,copper exhibits a valency of $+1$,and oxygen exhibits a valency of $-2$. By crossing the valencies,we get $Cu_{2}O$.
In cupric oxide,copper exhibits a valency of $+2$,and oxygen exhibits a valency of $-2$. By crossing the valencies,we get $Cu_{2}O_{2}$,which simplifies to $CuO$.
In cuprous oxide,copper exhibits a valency of $+1$,and oxygen exhibits a valency of $-2$. By crossing the valencies,we get $Cu_{2}O$.
