Осуществите превращение
1) Li- Li2O-LiOH-LiNO3
2)S-SO2-Na2SO3-BaSO3
3)P-P2O5-x?-Na3PO4-Ca3(PO4)2

Prikolist5221 1) O2 + 4Li = 2Li2O
Li2O + H2O = 2LiOH
LiOH + HNO3 = LiNO3 + H2O

2) S + O2 = SO2
SO2 + 2NaOH = Na2SO3 + H2O
Na2SO3 + Ba(OH)2 = BaSO3 + 2NaOH

3) 4P + 5O2 = 2P2O5
P2O5 + 3H2O = 2H3PO4
3NaOH + H3PO4 = Na3PO4 + 3H2O
2Na3PO4 + 3CaCl2 = Ca3(PO4)2↓ + 6NaCl

ekaterinasitki 1) 4Li+O2=2Li2O
Li2O + H2O = 2LiOH
LiOH+HNO3=LiNO3+H2O
2) S+O2=SO2
SO2 + 2NaOH(конц.) = Na2SO3 + H2O
Na2SO3+BaCl2=BaSO3↓+2NaCl
3) 4P+5O2=2P2O5
3H2O+P2O5=2H3PO4 - x
3NaOH(конц.) + H3PO4(разб.) = Na3PO4 + 3H2O
2Na3PO4 + 3CaCl2 = Ca3(PO4)2↓ + 6NaCl
