Question

duduce the formula of sodium carbonate
and calcium biocarbonate and aluminium oxide and potassium oxide and ferrous sulphate and zinc nitrate and copper chloride and ammonium sulphate​

Answer 1

Answer:

The chemical formula of the compounds is as follows:

sodium carbonate - $Na_{2} CO_{3}$

calcium bicarbonate - $Ca(HCO_{3} )_{2}$

aluminium oxide - $Al_{2} O_{3}$

potassium oxide - $K_{2} O$

ferrous sulphate - $FeSO_{4}$

zinc nitrate - $Zn(NO_{3} )_{2}$

copper chloride - $CuCl_{2}$

ammonium sulphate - $(NH_{4} )_{2} SO_{4}$

Explanation:

Sodium carbonate contains 2 sodium, 1 carbon and 3 oxygen atoms.

Calcium bicarbonate contains 1 calcium, 2 hydrogen, 2 carbon and 6 oxygen atoms.

Aluminium oxide contains 2 aluminium and 3 oxygen atoms.

Potassium oxide contains 2 potassium and 1 oxygen atoms.

Ferrous sulphate contains 1 iron, 1 sulphur and 4 oxygen atoms.

Zinc nitrate contains 1 zinc, 2 nitrogen and 6 oxygen atoms.

Copper chloride contains 1 copper and 2 chlorine atoms.

Ammonium sulphate contains 2 nitrogen, 8 hydrogen, 1 sulphur and 4 oxygen atoms.
