Answer 1

Ответ:

4P + 3O2 = 2P2O3

6Li + N2 = 2Li3N

Zn + 2HCl = ZnCl2 + H2

Fe(OH)3 + 3 HCl = 3H2O + FeCl3

3BaCl2 + Al2(SO4)3 = 2AlCl3 + 3BaSO4

Задание 2.

Ba + 2H2O = Ba(OH)2 + H2

4N + 3O2 = 2N2O3

Fe(OH)3 = Fe2O3 + 3H2O

Answer 2

Ba+2H2O= BA(OH)2+H2

2N2+3O2= 2N2O3

2Fe(OH)3 →Fe2O3+ 3H2O

Al(NO3)3+ Na3PO4= 3NaNO3+AlPO4

H2SO4+ 2NaOH= NaSO4+ 2H2O
