Answer to Question #94961 in General Chemistry for lane dodge

Question

Write the balanced NET ionic equation for the reaction when Na₂S and NiSO₄ are mixed in aqueous solution. If no reaction occurs, write only NR.

Answer 1

Na₂S(aq)+NiSO₄(aq) →Na₂SO₄(aq)+NiS(s)

2Na⁺(aq)  +S^2-(aq)  + Ni²⁺(aq) + SO₄^2-(aq) →2Na⁺(aq) ₊ SO₄^2- (aq) + NiS(s)

Ni²⁺(aq)  + S^2-(aq)   → NiS(s)
