Question

С какими веществами NaOH,H2SO4, MgO, H2O,CaCl взаимодействуют K2O,Fe2O3, N2O5

Answer 1

1) K2O + H2O = 2KOH
K2O + H2SO4 = K2SO4 + H2O
2) Fe2O3 + 3H2SO4 = Fe2(SO4)3 + 3H2O
Fe2O3 + 3H2O = 2Fe(OH)3
Fe2O3 + 6NaOH = 2Fe(OH)3 + 3Na2O
3) N2O5 + H2O = 2HNO3
N2O5 + 2NaOH = 2NaNO3 + H2O
N2O5 + MgO = Mg(NO3)2

Answer 2

1) K2O + H2SO4 = K2SO4 + H2O

  K2O + H2O = 2KOH

2) Fe2O3 + 3H2SO4 = Fe2(SO4)3 + 3H2O

3) N2O5 + 2NaOH = 2NaNO3 + H2O

   N2O5 + MgO = Mg(NO3)2

   N2O5 + H2O = 2HNO3
