A.Copper (II) sulphate
B.Calcium fluoride
C.Aluminum bromide
D.Zinc sulphate
E.Ammonium sulphate

Answer 1

Hint: 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.
-For example: The chemical formula of water is ${H_2}O$ . It says that two hydrogen atoms combine with one oxygen atom to form one molecule of water.
-Now let’s write the chemical formula of the given compounds.
1.Copper (II) sulphate- Its chemical formula is $CuS{O_4}$ ${({H_2}0)_x}$ where x can range from 0-5. Older names of this compound are blue vitriol, bluestone, vitriol of copper and Roman vitriol.
2.Calcium Fluoride- It is an inorganic compound of elements calcium and fluoride with the chemical formula $Ca{F_2}$ .It is basically a white insoluble solid.
3.Aluminum bromide- It is a compound with the chemical formula $AlB{r_3}$ . It is basically a white to pale yellow powder and has a pungent odor.
4.Zinc Sulphate- It is an inorganic compound and a dietary supplement with the chemical formula $ZnS{O_4}$ . It is used to treat zinc deficiency.
5.Ammonium sulphate- It is an inorganic salt with chemical formula ${(N{H_4})_2}S{O_4}$ .It is most commonly used as a soil fertilizer.

Note:
The empirical formula of a compound represents the ratio of the elements present in the compound. It is usually obtained by the analysis of experimental data. For example, the empirical formula of glucose is $C{H_2}O$ and it can further be derived by the molecular formula.
