Write correct formulas for the products in these double replacement reactions.
1) Ca(OH)2 + H3PO4 ---> Ca3(PO4)2 + H2O
2) K2CO3 + BaCl2 ---> KCl + BaCO3
3) Cd3(PO4)2 + (NH4)2S ---> CdS + (NH4)3PO4
4) Co(OH)3 + HNO3 ---> Co(NO3)3 + H2O
5) AgNO3 + KCl ---> AgCl + KNO3
6) Na2CO3 + H2SO4 ---> Na2SO4 + CO2 + H2O
7) Al(OH)3 + HC2H3O2 ---> Al(C2H3O2)3 + H2O
8) Al2(SO4)3 + Ca3(PO4)2 ---> AlPO4 + CaSO4
9) Cr2(SO3)3 + H2SO4 ---> Cr2(SO4)3 + SO2 + H2O
10) AgC2H3O2 + K2CrO4 ---> Ag2CrO4 + KC2H3O2
Here are more examples of the decomposition into gas and water:
KOH + (NH4)2SO4 --->
(NH4)3PO4 + Mg(OH)2 --->
(NH4)2SO4 + Ca(OH)2 --->
MnO2 + HCl ---> MnCl2 + Cl2 + H2O
Actually, this last one is a bit of an oddball at this beginning level. The ChemTeam would not ask it on a test, but the other three would be fair game.
