Write the balanced chemical equations for the following reactions and identify the type of reaction in each case.

(a) Nitrogen gas is treated with hydrogen gas in the presence of a catalyst at 773 K to form ammonia gas.

(b) Sodium hydroxide solution is treated with acetic acid to form sodium acetate and water.

(c) Ethanol is warmed with ethanoic acid to form ethyl acetate in the presence of concentrated H₂SO₄.

(d) Ethane is burnt in the presence of oxygen to form carbon dioxide, water and releases heat and light.

Chemical Reactions and Equations

(a)

This is an example of combination reaction. A combination reaction is one in which or more reactants combine to form a single product.

(b) NaOH (aq)+CH₃COOH()CH₃COONa(aq)+H₂O()

This is an example of neutralisation reaction between a strong base and weak acid. A neutralisation occurs between an acid and a base to form water and salt. This reaction releases H⁺ and OH^- ions. It is also a double displacement reaction. In such reaction cations and anions of both reactants exchange their places.

(c) C₂H₅OH(aq)+CH₃COOH()CH₃COO C₂H₅ (aq)+H₂O()

This is an example of neutralisation reaction as double displacement reaction.

A neutralisation occurs between an acid and a base to form water and salt. This reaction releases H⁺ and OH^- ions. It is also a double displacement reaction. In such reaction cations and anions of both reactants exchange their places.

(d) C₂H₄(g)+3O₂(g) 2CO₂(g) + 2H₂O(g)+Heat + Light

This is an example of oxidation reaction. The reactant burns in oxygen to produce carbon dioxide and water. It is also an exothermic reaction as it evolves a lot of heat. It is also known as oxidation reaction.
