A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds. Hence it is an example of decomposition reaction.

Solve any question of Chemical Reactions and Equations with:-

Answer 2

To carry out the above chain of transformations, it is necessary to carry out the following reactions:

Chemical reaction and equation The reaction produces carbon monoxide. The reaction proceeds as a compound.

CO2 + C = 2 CO

Carbon monoxide react with oxygen. The reaction produces carbon dioxide. Redox reaction.

2 CO + O2 = 2 CO2

Chemical reaction and equation As a result of the reaction, sodium carbonate is formed and water is released.

CO2 + 2 NaOH = Na2CO3 + H2O

Sodium carbonate react with carbonic acid. As a result of the reaction, sodium bicarbonate is formed. The reaction proceeds as a compound.

H2CO3 + Na2CO3 = 2 NaHCO3

The decomposition of sodium bicarbonate. The reaction produces sodium carbonate, carbon dioxide and water.

2 NaHCO3 = Na2CO3 + CO2 + H2O

The decomposition of sodium carbonate to sodium oxide and carbon dioxide.

Na2CO3 = Na2O + CO2.
