Carbon and silicon are present in the same group. Their dioxides `CO_2` and `SiO_3` show some similarities. For example both are acidic oxides.
The basic building blocks of silicates are `SiO_4^(4-)` tetrahedral. Differentiate ortho-silicates and pyrosilicates.

Carbon and silicon are present in the same group. Their dioxides CO_2 and SiO_3 show some similarities. For example both are acidic oxides. But CO_2 is a gas, SIO_2 is a solid. Account.
