Question

Oxygen supports combustion and is used up in burning.
A. True
B. False

Answer 1

Hint: The concept of combustion process that is combining of oxygen with other chemicals and release of heat by the reaction and also can get ignited and this fact involves the required answer to the given question.

Complete answer:
> In the chapters of the chemistry class, we have come across the concept of various types of reactions like degradation reaction, combustion reaction, oxidation reaction and many other reactions which are also included in the biochemistry part.
> Now, we shall see what actually is the combustion reaction and how it takes place and what it can produce. This will help us to approach the answer.
> Combustion reaction is defined as the reaction which a substance reacts with the oxygen in air and releases energy which is in the form of heat and light.
> The main requirement for the combustion reaction to take place is the involvement of oxygen as one of the reactants.
> The best example for this type of reaction is the combustion reaction of hydrogen gas to form water vapour.
> Combustion, on the other hand, is the scientific word used to refer to the process of burning.
> This combustion reaction is accompanied by the release of heat or generation of heat and light in the form of flame. The reaction is the oxidation reaction taking place.

> Therefore, the oxygen supports combustion and is used up in burning and the given statement is true.

Thus, the correct answer is option A. True.

Note: Usually the products of the combustion reactions are the oxides and this reaction also depends on whether it takes place completely or incompletely that is complete combustion or incomplete combustion (Occurs when there is not enough oxygen for the fuel to react completely). Apart from these, the other types are spontaneous, rapid and explosive combustion.
