CaO+HCl= Li2+O+H2O= Rb+H2O= CaCl2+H2SO4= Na=Na2O=NaCl=NaNo3=Na2SO4 решение этих вопросов

Question

CaO+HCl=
Li2+O+H2O=
Rb+H2O=
CaCl2+H2SO4=
Na=Na2O=NaCl=NaNo3=Na2SO4
решение этих вопросов

Answer 1

CaO + 2HCl = CaCl2 + H2O
Li2O + H2O = 2LiOH
2Rb + 2H2O = 2RbOH + H2
CaCl2 + H2SO4 = CaSO4 + 2HCl
Na=Na2O=NaCl=NaNo3=Na2SO4
1) 4Na + 2O2 = 2Na2O
2) Na2O + 2HCl = 2NaCl + H2O 
3) NaCl + HNO3 = NaNO3 + HCl
4) 2NaNO3 + H2SO4 = Na2SO4 + 2HNO3
