Question

Na2O5+H2O
K+H2O
Al(OH)3+HNO3
CaO+H2O
Mg+HCl

Answer 1

N2O5(,скорее всего)+H2O=2HNO3
2K+2H2O=2KOH+H2
Al(OH)3+HNO3=Al(NO3)3+H2O
CaO+H2O=Ca(OH)2
Mg+2HCl=MgCl2+H2

Answer 2

N2O5 + H2O -> 2HNO3
2K + 2H2O -> 2KOH + H2
 Al(OH)3 + 3HNO3 -> Al(NO3)3 + 3H2O
 CaO + H2O -> Ca(OH)2
 Mg + 2HCl -> MgCl2 + H2
