Give molecular, ionic, net ions, Spectator ions, Driving force and label each Strong electrolyte, weak electrolyte, and non electrolyte, as well as solid, liquid and gas.

a) CaCl2 + (NH4)3 PO4 --->

b) HClO4 + Na2CO3 ---->

a) CaCl2 + (NH4)3 PO4 --->

Ca3(PO4)2 is likely to form, since it is not soluble

balanced equation

3CaCl2(aq) + 2(NH4)3PO4(aq) --> Ca3(PO4)2(s) + 6NH4Cl(aq)

ionic

3Ca+2(aq) + 6Cl-(aq) + 6(NH4+) + 2PO4-3(aq) --> Ca3(PO4)2(s) + 6NH4+(aq) + 6Cl-(aq)

spectator ions --> NH4+ and Cl-

net ionic equation:

3Ca+2(aq) + 2PO4-3(aq) --> Ca3(PO4)2(s)

NH4+ and Cl- = strong electrolytes

Ca3(PO4)2(s) = nonelectrolyte

Q2.

HClO4 + Na2CO3 ---->

this is acid ´base reaction

molecular balanced equation

2HClO4(aq) + Na2CO3(aq) --> 2H2O(l) + CO2(g) + NaCl(aq)

ionic equation

2H+(aq) + 2ClO4-(aq) + 2Na+(aq) + CO3-2(aq) --> 2H2O(l) + CO2(g) + Na+(aq) + ClO4-(aq)

spectator ions --> Na+ and Cl-

net ionic equation

2H+(aq) + CO3-2(aq) --> 2H2O(l) + CO2(g)

strong eletrolyes = Na+ and ClO4-

nonelectrolyte = H2O and CO2
