Ответ:
H2 + Cl2 = 2HCl
2H3PO4 + 3MgO = Mg3(PO4)2 + 3H2O
3CaCl2 + 2K3PO4 = Ca3(PO4)2 + 6KCl
2Zn + O2 = 2ZnO
3Ca + N2 = Ca3N2
Ca + 2HCl = CaCl2 + H2
Mg + CuCl2 = MgCl2 + Cu
3Zn + 2FeCl3 = 3ZnCl2 + 2Fe
2HNO3 + Ca(OH)2 = Ca(NO3)2 + 2H2O
2Al + 3S = Al2S3
F2 + 2KBr = 2KF + Br2
Fe2(SO4)3 + 6NaOH = 3Na2SO4 + 2Fe(OH)3
