The Chemistry of Carbon - Purdue University

Egg shells are almost pure calcium carbonate. CaCO 3 can also be found in the shells of many marine organisms and in both limestone and marble. The fact that none of these substances dissolve in water suggests that CaCO 3 is normally insoluble in water.


most common pure silicon oxide is silicon dioxide. This can be used to make silica gel, packets of which are used to keep items free of moisture. To make silica gel, solid silicon dioxide must be reacted in 1:2 ratio with sodium carbonate at

Silicones - Essential Chemical Industry

Silicon is first converted into chlorosilanes, e.g. RSiCl 3, R 2 SiCl 2 and R 3 SiCl, where R is an organic group. When chloromethane is passed through heated silicon at about 550 K under slight pressure and in the presence of a copper alyst (often copper itself but other copper-containing materials can be used, for example, brass or copper(II) chloride) a volatile mixture of chlorosilanes
