Solutions of calcium iodide and lead nitrate are mixed together. A reaction occurs where a solid forms at the bottom of the beaker. This is a precipitate of lead iodide. Calcium nitrate is also product but it stays in solution as ions because it is soluble. Write the equation for this reaction making sure that it is balanced electronically and atomically. Remember, the result is calcium nitrate and lead (II) iodide.

1. Ca(NO3) + PbI => CaI + Pb(NO3)

2. CaI2 + Pb(NO3)2 => Ca(NO3)2 + PbI2

3. Ca(NO3)2 + PbI2 => CaI2 + Pb(NO3)2

4. Ca2(NO3) + Pb2I => Ca2I + Pb2(NO3)

5. Ca(NO3) + PbI2 => CaI + Pb(NO3)2
