Question

Write a balanced net ionic equation for the reaction of NiBr₂(aq) with (NH₄⁺)2S(aq).

Answer 1

To write the balanced net ionic equation, first write the complete ionic equation and then cancel out spectator ions.

Step-by-step explanation:

A balanced net ionic equation represents the ions that are directly involved in a chemical reaction. To write the balanced net ionic equation for the reaction of NiBr₂(aq) with (NH₄⁺)2S(aq), we first need to write the complete ionic equation and then cancel out spectator ions.

The complete ionic equation for the reaction is:

`2 Ni²⁺(aq) + 4 Br⁻(aq) + 2 NH₄⁺(aq) + S²⁻(aq) → 2 NiS(s) + 8 Br⁻(aq) + 2 NH₄⁺(aq)`

Next, we cancel out the spectator ions (Br⁻ and NH₄⁺) on both sides of the equation:

Net ionic equation:

`2 Ni²⁺(aq) + S²⁻(aq) → 2 NiS(s)`
