Question #81278
Always put the cation first and the anion second. For the net ionic equations type your answer using the format Ga3+(aq) + 3OH-(aq) -> Ga(OH)3(s) for Ga3+(aq) + 3 OH-(aq) Ga(OH)3(s). Note: The "arrow" is made with the minus "-" and greater than ">" key. You must put the states of matter (s), (l), (g), or (aq). Do not add any spaces to your equation. For listing the spectator ions, use the format Ca2+, SO42- for the pair of ions Ca2+, SO42-.
(a) Pb(NO3)2 (aq) + Na2SO4 (aq)
net ionic equation
(b) CuBr2 (aq) + NaOH (aq)
net ionic equation
(c) AgNO3 (aq) + KI (aq)
net ionic equation

(b) CuBr2 (aq) + NaOH (aq)
net ionic equation
(c) AgNO3 (aq) + KI (aq)
net ionic equation
Answer:
(a) Net ionic equation: Pb2+(aq) + SO42- (aq) -> PbSO4 (s). Spectator ions: cation Na+(aq), anion NO3-(aq),
(b) Net ionic equation: Cu2+ (aq) + 2OH-(aq) -> Cu(OH)2(s). Spectator ions: cation Na+(aq), anion Br-(aq),
(c) Net ionic equation: Ag+(aq) + I-(aq) -> AgI(s). Spectator ions: cation K+(aq), anion NO3-(aq),
