Question

Qill(a) Write the molecular formula of the following
1. Zinc sulphate 2. Magnesium hydroxide
3. Sodium chloride

Answer 1

Answer:

1. The molecular formula of  Zinc sulphate is ZnSO₄. Zinc sulfate is a drug used to replenish low levels of zinc or prevent zinc deficiency, or test for zinc deficiency.

2. The molecular formula of  Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH)2. It occurs in nature as the mineral brucite.

3. The molecular formula of  Sodium chloride is commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl,

Answer 2

Zinc sulphate
