Question

CH4 +O2= CaO +H2O= SO3 +H2O=

Answer 1

Ответ:

CH4 + 2O2 = CO2 + 2H2O

СaO + H₂O = Ca(OH)₂ -гидроксид кальция

SO3+H2O=H2SO4

Answer 2

1) CH4 (g) + 2 O2 (g) → 2 H2O (l) + CO2 (g)
2) CaO + H2O → Ca(OH)2
3) SO3 (l) + H2O (l) → H2SO4 (aq)

Answer 3

The equations you provided seem to be incomplete or incorrect. Let me correct and complete them for you:

1. CH4 + 2O2 → CO2 + 2H2O This balanced equation represents the combustion of methane (CH4) in the presence of oxygen (O2) to form carbon dioxide (CO2) and water (H2O).

2. CaO + H2O → Ca(OH)2 This balanced equation represents the reaction between calcium oxide (CaO) and water (H2O) to form calcium hydroxide (Ca(OH)2). This reaction is commonly known as slaking of lime.

3. SO3 + H2O → H2SO4 This balanced equation represents the reaction between sulfur trioxide (SO3) and water (H2O) to form sulfuric acid (H2SO4). This reaction is an example of a highly exothermic reaction and is used in the production of sulfuric acid.

Please note that these equations are balanced using stoichiometric coefficients to represent the conservation of atoms in a chemical reaction.
