Question

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 773K 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) Ethene is burnt in the presence of oxygen to form carbon dioxide, water and releases heat and light.

Answer 1

a) N2 + 3H2 = 2NH3.. Combination reaction
b) NaOH + CH3COOH = CH3COONa + H2O
Neutralisation reaction
c) C2H5OH + CH3COOH = CH3COOC2H5 + H2O esterification reaction
d) C2H4 + 3O2 = 2CO2 + 2H2O + heat and light combustion reaction

Answer 2

Answer:

1. $N_2+3H_2\rightarrow 2NH_3$ : Synthesis

Synthesis reaction is a chemical reaction in which two reactants combine to form one product.

2. $NaOH+CH_3COOH\rightarrow CH_3COONa+H_2O$ : Neutralization

Neutralization reaction is a chemical reaction in which acid and base reacts to form salt and water.

3. $C_2H_5OH+CH_3COOH\rightarrow CH_3COOC_2H_5+H_2O$ : Esterification

Esterification reaction is a chemical reaction in which an acid and alcohol reacts to form ester and water.

4. $C_2H_4+3O_2\rightarrow 2CO_2+2H_2O$ : Combustion

Combustion reaction is a chemical reaction in which hydrocarbon is reacted with oxygen to form carbon dioxide and water.
