Question

Egalati urmatoarele reactii chimice, dupa ce stabiliti ce produsi se formeaza:

Na2CO3+Ca(OH)2->
KCl+H2S->
MgCl2+H2->
Al(OH)3+HF->
NaOH+HBr->
BF3+H2O->
B2O3+HCl->
PbO2+HCl->
CaF2+H2SO4->
FeS+HCl->
NH4Cl+Ca(OH)2->

Answer 1

Na2CO3 + Ca(OH)2 → 2NaOH + CaCO3
2KCl + H2S → K2S + 2HCl
MgCl2 + H2 → Mg + 2HCl
Al(OH3) + HF → AlF3 + H2O
NaOH + HBr → NaBr + H2O
BF3 + 3H2O → H3BO3 + 3HF
B2O3 + 6HCl → 2BCl3 + 3H2O
PbO2 + 4HCl → PbCl4 + 2H2O
CaF2 + H2SO4 → CaSO4 + 2HF
FeS + 2HCl → FeCl2 + H2S
2NH4Cl + Ca(OH)2 → CaCl2 + 2NH3 + 2H2O
