Considering the following precipitation reaction: Pb(NO3)2(aq) + 2KI(aq) → Pbl2(s) + 2KNO3(aq) What is the correct complete ionic equation? O1. Pb2+ + 2NO3- + 2K+ + 21-→ Pb2+ + 21- + 2K+ + 2NO3- O II. Pb2+ + (NO3)2¯ + 2K+ + 21- → Pbl2(s) + 2K+ + 2NO3- O II. Pb2+ + 2NO3 +2K+ + |-→ Pbl2(s) + 2K+ + NO3- O IV. Pb2+ + 2NO3- + 2K+ + 21- Pbl2(s) + 2K+ + 2NO3

Be sure to specify states such as (aq) or (s). If a box is not needed leave it blank. Write the net ionic equation for the following molecular equation. MgSO4(aq) + Na₂CO3(aq) MgCO3(s) + Na₂SO4(aq) + +

complete and balance the following molecular equations, and then write the net ionic equation for each. a.  HBr9aq) + Ca9OH)2 b.  Cu(OH)2 (s) + HClO4 (aq) c.  Al(OH)3 (s) = HNO3(aq)

Are these correct ?

Help please

17. Predict whether or not a precipitation reaction will occur if the pairs of solutions that are given below are mixed. If you think a reaction will occur, write a balanced equation for the precipitation reaction. Na,S0,(aq) + K2CO3(aq)→ К,со, (аq) + Са(NO;3)2(aq) > СаCl2(aq) + NaNO3(аq) — СаCl2(aq) + 2AgNO,(aq) —
