Question

Восстановите уравнения реакций:
a)4Al + ... = 2Al2O3
b)4Li + O2 = ...
c)MgO + ... = Mg(NO3)2
d)Na2O + ... = 2NaOH

Answer 1

)4Al  + 3O2= 2Al2O3
b)4Li + O2 = 2Li2O
c)MgO + N2O5... = Mg(NO3)2
d)Na2O + .Н2О.. = 2NaOH

Answer 2

A) 4Al + 3O2 = 2Al2O3
b) 4Li + O2 = 2Li2O
c) MgO + 2HNO3 = Mg(NO3)2 + H2O
d) Na2O + H2O = 2NaOH
