Question

Q. Write the chemical equation to represent what happens when, (a) Ethanol burns in air (b) ethanol reacts with sodium (b) Sodium hydroxide reacts with ethanoic acid (d) solid sodium bicarbonate reacts with ethanoic acid.

Answer 1

1) When ethanol burns in air :
C₂H₅OH + 3O₂ $\to$2CO₂ + 3H₂O

2) Ethanol reacts with sodium :
2C₂H₅OH + 2Na $\to$2C₂H₅ONa + H₂

3) Sodium hydroxide reacts with ethanoic acid :
CH₃COOH + NaOH $\to$CH₃COONa + H₂O

4) Solid sodium bicarbonate reacts with ethanoic acid :
CH₃COOH + NaHCO₃ $\to$CH₃COONa + H₂O + CO₂
