HCl+MgO=HNO3+MgO=NaOH+MgO=P2O5+MgO=

Question

HCl+MgO=
HNO3+MgO=
NaOH+MgO=
P2O5+MgO=

Answer 1

2HCl + MgO = MgCl2 + H2O
2HNO3 + MgO = Mg(NO3)2 + H2O
NaOH + MgO = не взаимодействует!
P2O5 + 3MgO = Mg3(PO4)2

Answer 2

2HCl+MgO=H2O+MgCl2
2HNO3+MgO=Mg(NO3)2+h2O
2NaOH+MgO=mg(oh)2+na2o
P2O5+3MgO=Mg3(po4)2
