Question

Соли Pb(NO3)2 + Sr = SnCl2 + Ba = CoI2 + NaOH = FeSO4 + LiOH = Na2CO3 + HBr = Pb(NO3)2 + H2SO4 = K3PO4 + ZnCl2 = AlF3 + Na2SiO3 = Al2(SO4)3 = Ca3(PO4)2 =

Answer 1

Pb(NO3)2 + Sr =Sr(NO3)2+Pb
SnCl2 + Ba =?
CoI2 + NaOH =Co(OH)2+Nal
FeSO4 + LiOH =Fe(OH)2+Li2SO4
Na2CO3 + 2HBr =2NaBr+H2CO3
Pb(NO3)2 + H2SO4 =2HNO3+PbSO4
K3PO4 + ZnCl2 =KCl+Zn3(PO4)2
AlF3 + Na2SiO3 =?
Al2(SO4)3 =Al2O3+3SO3
Ca3(PO4)2 =?

Answer 2

1. Pb(NO3)2 + Sr = PbSO4 + Sr(NO3)2
2. SnCl2 + Ba = Sn(NO3)2 + BaCl2
3. CoI2 + NaOH = Co(OH)2 + NaI
4. FeSO4 + LiOH = Fe(OH)2 + Li2SO4
5. Na2CO3 + HBr = NaBr + H2O + CO2
6. Pb(NO3)2 + H2SO4 = PbSO4 + 2 HNO3
7. K3PO4 + ZnCl2 = KCl + Zn3(PO4)2
8. AlF3 + Na2SiO3 = NaF + Al2SiO5
9. Al2(SO4)3 + 3NaOH = 2Al(OH)3 + 3Na2SO4
10. Ca3(PO4)2 + 2HCl = 2CaCl2 + H3PO4
