Question

Rb2O+H2O, SrO+H2O, NaOH+SIO2, LIOH+H2SO4, SIO2+H2O, CuO+H2O

Answer 1

Rb2O+H2O=2RbOH

SrO+H2O=Sr(OH)2

NaOH+SiO2=NaSiO2 + H20

2LiOH + H2SO4 = Li2SO4+2H2O

SiO2+H2O=H2SiO3

CuO+H2O=Cu(OH)2

Answer 2

Here are the balanced chemical equations for the given reactions:

1. Rb2O + H2O -> 2 RbOH
2. SrO + H2O -> Sr(OH)2
3. NaOH + SiO2 -> Na2SiO3 + H2O
4. LiOH + H2SO4 -> Li2SO4 + 2 H2O
5. SiO2 + H2O -> H2SiO3
6. CuO + H2O -> Cu(OH)2

Please note that these equations represent the balanced chemical reactions between the given compounds.
