Question

. Write down chemical formula:Sodium oxide g) Potassium sulphateCalcium carbonate h) Aluminium chlorideCopper nitrate i) Sodium suphide Magnesium hydroxide j) Calcium chlorideZinc oxide k) Ammonium sulphateAluminium sulphate

Answer 1

Sodium oxide = SO4
potassium sulphate =KSO4
Calcium carbonate =CaCO3
Aluminium chloride=Al2Cl3
copper nitrate=CuNO3
Sodium suphide=Na2S
Magnesium hydroxide=Mg{OH}2
Calcium chloride=CaCl2
Zinc oxide=ZnO
Ammonium sulphate=NH4SO4
aluminium sulphate =Al{SO4}3
