1 вариант:
4Fe + 3O2 = 2Fe2O3
2NaNO3 = 2NaNO2 + O2
3CuO + 2Al = Al2O3 + 3Cu
2AgNO3 + Cu = Cu(NO3)2 + 2Ag
2HBr = H2 + Br2
2Ca + O2 = 2CaO
CuCl2 + 2NaOH = Cu(OH)2 + 2NaCl
2KOH + H2SO4 = K2SO4 + 2H2O
-------------------------------------
2 вариант:
2CO + O2 = 2CO2
2KClO3 = 2KCl + 3O2
2Al + 6HCl = 2AlCl3 + 3H2
4Al + 3O2 = 2Al2O3
Fe + 2HCl = FeCl2 + H2
2KNO3 = 2KNO2 + O2
FeCl2 + 2KOH = Fe(OH)2 + 2KCl
Ca(OH)2 + 2HCl = CaCl2 + 2H2O
