Question

K2O+H20= Na2O+H20= SO3+H2O= BaO+H20=

Answer 1

K2O+H2O=2KOH

Na2O+H2O=2NaOH

SO3+H2O=H2SO4

BaO+H2O=Ba(OH)2

Answer 2

It looks like you've provided a list of chemical reactions. I'll provide you with the balanced chemical equations for each of these reactions:

1. K₂O + H₂O → 2 KOH

2. Na₂O + H₂O → 2 NaOH

3. SO₃ + H₂O → H₂SO₄

4. BaO + H₂O → Ba(OH)₂

These equations represent the reactions between the given compounds and water to form new products. If you have any further questions or need additional explanations, feel free to ask!
