Answer 1

Растворимые
2Na+2H₂O-->2NaOH+H₂
K₂O+H₂O-->2KOH
2Li+2H₂O--->2LiOH+H₂
CaO+H₂O-->Ca(OH)₂
Ba+2H₂O-->Ba(OH)₂+H₂
2K+2H₂O-->2KOH+H₂
Нерастворимые:
2NaOH+ZnCl₂-->Zn(OH)₂+2NaCl
AlCl₃+3KOH-->Al(OH)₃+3KCl
CuSO₄+2NaOH-->Cu(OH)₂+Na₂SO₄
3LiOH+FeCl₃-->Fe(OH)₃+3LiCl
Ni(NO₃)₂+2NaOH-->Ni(OH)₂+2NaNO₃
Mn(NO₃)₂+2NaOH-->Mn(OH)₂+2NaNO₃
CrCl₃+3KOH--->Cr(OH)₃+3KCl

Answer 2

№1.
2Na + 2H2O => 2NaOH + H2
K2O + H2O => 2KOH
2Li + 2H2O => 2LiOH + H2
CaO + H2O => Ca(OH)2
Ba + 2H2O => Ba(OH)2 +  H2
2K + 2H2O => 2KOH + H2

№2.
ZnCl2 + 2KOH => Zn(OH)2 + 2KCl
AlCl3 + 3KOH => Al(OH)3 + 3KCl
CuSO4 + 2NaOH => Cu(OH)2 + Na2SO4
Fe(NO3)3 + 3LiOH => Fe(OH)3 + 3LiNO3
NiCl2 + 2NaOH => Ni(OH)2 + 2NaCl
Mn(NO3)2 + 2KOH => Mn(OH)2 + 2KNO3
Cr2(SO4)3 + 6KOH => 2Cr(OH)3 + 3K2SO4
