Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of ammonium phosphate and nickel(II) bromide are combined. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed leave it blank.

Explanation:

Hello,

In this case, the molecular chemical reaction is:

Thus, by considering the ionic species we have:

Wherein the ammonium and bromide ions are spectator ions since nickel (II) phosphate is largely insoluble in water, therefore, the net ionic equation is:

Best regards.

i'm pretty sure its b i might be wrong though!
