In non-tropical countries, the major component of sand is silica, and so the chemical formula for sand is therefore SiO2. In silica, the ratio of the number of silicon atoms to the number of oxygen atoms is 1:2.Know More
In sand, this silica usually exists in the form of quartz. Quartz has a chemical formula of SiO2 and adopts a crystal structure where every silicon atom is attached to four oxygen atoms and every oxygen atom is attached to two silicon atoms. In some countries, sand is also made up of calcium carbonate. The chemical formula for calcium carbonate is CaCO3.Learn more about Chemistry
The chemical formula for a diamond is simply C. Diamonds are carbon atoms arranged in a specific way. Graphite and soot also have chemical formulas of C because they are carbon atoms, like diamonds are, just in different arrangements of molecules.Full Answer >
The chemical formula for chromium (II) nitrate is Cr(NO3)2. The chromium (II) ion has a positive charge of two, and each nitrate ion contain a single negative charge; two nitrate ions can bond to form an electrically stable compound.Full Answer >
