Объяснение:
1) 4Li + O2 = 2Li2O
Li2O + H2O = 2LiOH
3LiOH + H3PO4 = Li3PO4 + 3H2O
2) Cu + Cl2 = CuCl2
CuCl2 + 2NaOH = Cu(OH)2 + 2NaCl
Cu(OH)2 -> CuO + H2O
3CuO +2Fe = Fe2O3 + 3Cu
3) 4Ag + O2 = 2Ag2O
Ag2O + 2HNO3 = 2AgNO3 + H2O
2AgNO3 -> 2Ag + 2NO2 + O2
2Ag + Br2 = 2AgBr
4) Fe + 2HCl = FeCl2 + H2
2FeCl2 + Cl2 = 2FeCl3
FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl
Fe(OH)3 +3 HCl = FeCl3 + 3H2O
2FeCl3 -> 2Fe + 3Cl2
