Answer 1

Answer:

HOPE IT WILL HELP YOU........

PLEASE MARK IT AS BRAINLIEST...........

Explanation:

• 2 CH3COOH (aq) + Na2CO3 (aq) → 2 CH3COONa (aq) + CO2 (g) + H2O (l)

This is an acid-base reaction (neutralization): CH3COOH is an acid, Na2CO3 is a base.

This is a gas evolution reaction, CO2 is the formed gas.

• CH4 (g) + 2 O2 (g) → 2 H2O (l) + CO2 (g)

This is an oxidation-reduction (redox) reaction.

• 2 C2H5OH + 2 Na → H2 + 2 C2H5ONa

This is an oxidation-reduction (redox) reaction:

2 Na - 2 e- → 2 Na (oxidation)

2 H + 2 e- → 2 H (reduction)
