Question

Li+H2O= Ca+H2O= BaO+H2O= CO2+H2O= Li2O+H2O= SO3+H2O=

Answer 1

Li + H2O → LiOH + H2

Ca + 2H2O → Ca(OH)2 + H2

BaO + H2O → Ba(OH)2 + H2

CO2 + H2O → H2CO3 (слабая, неустойчивая кислота. Сразу распадается на H2O и CO2)

Li2O + H2O → 2LiOH

SO3 + H2O → H2SO4

Answer 2

Here are the chemical reactions for the given combinations:

1. Li + H2O (Lithium + Water) -> LiOH (Lithium Hydroxide) + H2 (Hydrogen gas)

2. Ca + H2O (Calcium + Water) -> Ca(OH)2 (Calcium Hydroxide) + H2 (Hydrogen gas)

3. BaO + H2O (Barium Oxide + Water) -> Ba(OH)2 (Barium Hydroxide)

4. CO2 + H2O (Carbon Dioxide + Water) -> H2CO3 (Carbonic Acid)

5. Li2O + H2O (Lithium Oxide + Water) -> 2LiOH (Lithium Hydroxide)

6. SO3 + H2O (Sulfur Trioxide + Water) -> H2SO4 (Sulfuric Acid)

Please note that in the above reactions, some of the products may exist in an ionized or dissociated form in the aqueous solution, depending on the concentration and conditions of the reaction.
