Ca NO Caci, Pb NO PbC 3 2 Make sure that you have the same number of each atom on both sides of the arrow. You also want to be sure that you have the correct format: subscript the number of each atom in a molecule, put the state of matter next to each compound, and put a number in front of each molecule to indicate how many of each molecule are present. Also, remember to remove the spectator ions to write the net ionic equation. Try Again View Solution 12 13 14 15 Progress 16 17 18 19 20 21 ade Solution amExplanation / Answer
1.
NH4(+)SO4(2-) + Ca(2+)CH3CO2(-)--------->
Ca(2+)SO4(2-) + NH4(+)CH3CO2(-)
solubility rules says that calcium sulfate is a solid. So yes there will be precipitation. All the other ions remain in solution so the net ionic equation contains only the ions that precipitate.
Ca(2+) aq + SO4(2-) aq ----> CaSO4(2-) solid
2. Equation:
Pb(NO3)2(aq) + CaCl2(aq) ? Ca(NO3)2(aq) + PbCl2(s)
The precipitate is PbCl2
