Solution

Dear student

1. Sodium bicarbonate
Na is Na⁺ and bicarbonate ion is HCO₃^-
When they exchange valencies, we get , NaHCO₃

2.Nitrite ion is NO₂^-

3.Silicon dioxide has the formula SiO₂.

4.Nitric acid has the formula HNO₃

5.Methane has the formula, CH₄

6.Barium chloride
Ba exists as Ba²⁺ion and Chloride is Cl^-
So when they exchange charges the compound becomes BaCl₂

7.Potassium permanganate
Potassium ion is K⁺ and Manganate ion is MnO₄^-
The formula after exchange of charges becomes KMnO₄
