Question

Write a net ionic equation for each. 1.excess nitric acid (aq) and iron(II) carbonate are combined. 2. nickel(II) sulfide and excess hydrochloric acid (aq) are combined. 3. excess nitric acid (aq) and barium sulfite (s) are combined

Answer 1

Part 1

Net ionic equation for the reaction of excess nitric acid (aq) and iron(II) carbonate

FeCO₃ (s) $\rightarrow$ Fe²⁺ (aq) + CO₃^2- (aq)

Part 2

Net ionic equation for the reaction of nickel(II) sulfide and excess hydrochloric acid (aq)

NiS +2H⁺ $\rightarrow$ Ni²⁺ + H₂S

Part 3

Net ionic equation for the reaction of excess nitric acid (aq) and barium sulfite (s)

3BaSO₃(s) + 2H⁺(aq) + 2NO₃^- $\rightarrow$ 3Ba²⁺(aq) + 3SO₄^2- + 2NO(g) + 2H₂O(l)
