Question

K2O+H2O=SO3+H2O=...+H2O=Ca(OH)2C+O2=

Answer 1

Ответ:

K2O + H2O → 2 KOH

SO3+H2O = H₂SO₄

Ca(OH)2 + 2CO2 + 0H2O → Ca(HCO3)2

Answer 2

It looks like you've provided a series of chemical reactions. Let's break them down one by one:

1. K2O + H2O:

   • This is the reaction between Potassium Oxide and Water.
   • It forms Potassium Hydroxide (KOH).

   The balanced chemical equation is:

   K2O + H2O → 2 KOH
   

2. SO3 + H2O:

   • This is the reaction between Sulfur Trioxide and Water.
   • It forms Sulfuric Acid (H2SO4).

   The balanced chemical equation is:

   SO3 + H2O → H2SO4
   

3. Ca(OH)2 + C:

   • This appears to be the reaction between Calcium Hydroxide and Carbon. However, this reaction is incomplete. We need more information to proceed. If you provide more context or specify what kind of reaction you're interested in, I can help further.

4. O2:

   • This represents the decomposition of molecular Oxygen. Oxygen gas (O2) is broken down into individual oxygen molecules.

   The balanced chemical equation is:

   2 O2 → 4 O
   

Please provide more information about the last part of your question (Ca(OH)2 + C + O2) so I can assist you with that specific reaction.
