Question

Oxygen is a neutral gas which supports combustion. True or False?

• A. True
• B. False

Answer 1

The correct option is A True

Explanation for the correct option:

Combustion reaction:

• A combustion reaction is known as a chemical reaction in which a fuel undergoes oxidation by reacting with an oxidizing agent, which results in the release of energy mostly in the form of heat.
• The combustion process basically generates gases i.e Carbon monoxide, Carbon dioxide, Sulfur dioxide, Nitrogen oxide, particulate matter, etc.
• Combustion reactions are always known to be exothermic in nature as heat often gets released in reactions.

Oxygen used in combustion:

• The combustion reactions can be easily determined as there is always the presence of Oxygen on the reactant side which mostly generates Carbon dioxide, and water vapors, and heat along with the reaction.
• The general combustion reaction can be given as :
  $\mathrm{Fuel}+\underset{\left(\mathrm{Oxygen}\right)}{{\mathrm{O}}_{\mathrm{2}}\left(\mathrm{g}\right)}\to \underset{(\mathrm{Carbon}\mathrm{dioxide})}{\mathrm{C}{\mathrm{O}}_{\mathrm{2}}\left(\mathrm{g}\right)}+\underset{\left(\mathrm{Water}\right)}{{\mathrm{H}}_{\mathrm{2}}\mathrm{O}\left(\mathrm{l}\right)}+\mathrm{heat}$
• In the combustion process, oxygen mostly acts as the oxidizer which helps in supporting the combustion process.

Therefore, the given statement saying ‘oxygen is neutral gas that supports combustion’ is true.
