Question

What is the chemical formula for quartz?

Answer 1

Hint : We know that chemical formula is an expression which shows the number and type of atoms present in one molecule of a substance. The chemical formula of a compound is a symbolic representation of its chemical composition. Moreover, the chemical formula provides an insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine.

Complete Step By Step Answer:
A chemical formula is defined as a collection of chemical symbols that is used to show the elements present in any compound and its proportion.
We have Quartz,
The chemical formula of quartz is $Si{O_2}$ , that is one silicon atom combined with two molecules of oxygen. Quartz is also called as Silica, which is a white or colourless crystalline compound found mainly as quartz, sand, flint and many other minerals.
Quartz is made up of a continuous framework of $Si{O_4}$ silicon-oxygen tetrahedral. Each oxygen atom is shared between two tetrahedral, giving an overall formula of $Si{O_2}$ . Thus the chemical formula of quartz is $Si{O_2}$ .

Note :
The empirical formula of a compound represents the ratio of the element present in the compound. It is usually obtained by the analysis of experimental data. Quartz is an abundant mineral in the earth’s continental crust. Quartz used in abrasives, foundry materials, ceramics and cements.
