Question

CaC2+2H2O=?CH4COONa+NaOH=?CH4+O2=?​

Answer 1

Ответ:

CaC2+H2O=Ca(OH)2 + C2H2

CH3COONa+NaON=CH4+NaCO3

CH4+O2=CO2+H2O

Answer 2

The chemical equations you've provided are:

1. CaC₂ + 2H₂O → ?
2. CH₄COONa + NaOH → ?
3. CH₄ + O₂ → ?

Let's balance and solve these equations:

1. CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂

   This equation represents the reaction of calcium carbide (CaC₂) with water (H₂O) to produce acetylene gas (C₂H₂) and calcium hydroxide (Ca(OH)₂).

2. CH₄COONa + NaOH → CH₄ + Na₂CO₃

   This equation represents the reaction of sodium acetate (CH₄COONa) with sodium hydroxide (NaOH) to produce methane gas (CH₄) and sodium carbonate (Na₂CO₃).

3. CH₄ + 2O₂ → CO₂ + 2H₂O

   This equation represents the combustion of methane gas (CH₄) in the presence of oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O).

Please note that the second equation seems a bit unusual. Sodium acetate doesn't typically react with sodium hydroxide in this manner. If you meant a different reaction or there was a typo, please provide more context or clarify.
