Question

Write their molecular, ionic equation, and provide if a reactions occurs ( liquid, gas, aqueous, solid) for the following :

1)Nickel (II) hydroxide with nitric acid yields a green solution.

2)Copper (II acetate with hydrogen sulfide yields a black solid.

3)Calcium fluoride with nitric acid.

4)Iron (II) carbonate with hydrochloride acid.

5)Strontium hydroxide with sulfuric acid.

6)Silver carbonate with acetic acid yields a clear, bubbly solution.

7)Iron (III) chloride with ammonia.

8)Hydrogen sulfide with zinc chloride.

9)Ammonium carbonate with potassium hydroxide.

Answer 1

1. Ni(OH)₂ (aq) + 2HNO₃ (aq) = Ni(NO₃)₂ (aq, green color)+ H2O (l)

2. Cu(CH₃COO)₂ (aq) + H₂S (g) = Cu₂S (s, black color) + 2CH₃COOH (aq)

3. CaF₂ (s) + 2HNO₃ (aq) = Ca(NO₃)₂ (aq)+ 2 HF (aq)

4. FeCO₃ (s) + 2HCl (aq) = CO₂ (g) + FeCl₂ (aq)+ H₂O(l)

5. H₂SO₄ (aq)+ Sr(OH)₂ (s)= 2 H₂O(l) + SrSO₄ (s)

6 Ag₂CO₃ (s) + 2CH₃COOH (aq) = 2CH₃COOAg (aq) + CO₂ (g) + H₂O (l)

7. FeCl₃ (aq) + 3NH₃ (g) + 3H₂O (l) = Fe(OH)₃ (s) + 3NH₄Cl (aq)

8. H₂S (g) + ZnCl₂ (aq)= ZnS (s) + 2HCl (aq)

9. (NH₄)₂CO₃ (aq)+ KOH (aq)= NH₃ (g) + H₂O (l) + K₂CO₃ (aq)
