Question

Reaction 1

Ni(NO3)2+NaBr

Write the BALANCED Molecular Equation   
Did a reaction Occur? If so, write the BALANCED complete ionic equation     
Write the formulas for the spectator ions   
Write the BALANCED net ionic equation    
Write the systematic name for the product

Answer 1

1. Ni(NO₃)₂(aq) + 2 NaBr(aq) --> 2 NaNO₃(aq) + NiBr₂ (s)

2. Yes reaction occurs, Nickel bromide precipitates

   Ni²⁺ + 2 NO₃^- + 2Na⁺ + 2Br^- --> 2Na⁺ + 2NO₃^- + Ni²⁺ + 2Br^-

3. Na⁺ (Sodium cation) , NO₃^- (Nitrate anion) are spectator ions because they are in ionic state in both sides

4. Ni²⁺ (aq) + 2Br^- (aq) --> NiBr₂ (s)

5.Ni(NO₃)₂ --- Nickel(II) nitrate, NaBr --- Sodium Bromide, NaNO₃ --- Sodium nitrate, NiBr₂ -- Nickel(II) bromide
