Vedclass · Answer

(A) Given that the formula of the metal chloride is $MCl$,the valency of metal $M$ is $+1$ because the valency of chlorine $(Cl)$ is $-1$.$1$. Oxide: The valency of oxygen $(O)$ is $-2$. By criss-cross method,the formula is $M_2O$.$2$. Bicarbonate: The valency of the bicarbonate ion $(HCO_3)$ is $-1$. Combining $M^{+1}$ and $HCO_3^{-1}$,the formula is $MHCO_3$.$3$. Sulphide: The valency of sulphur $(S)$ is $-2$. By criss-cross method,the formula is $M_2S$.

The chemical formula of the chloride of a metal $M$ is $MCl$. Write the chemical formula of its oxide,bicarbonate,and sulphide.
