Question

A combustion reaction (burning a candle, for instance) is an example of which of the following processes?

a) Oxidation
b) Reduction
c) Hydrolysis
d) Precipitation

Answer 1

A combustion reaction is a redox reaction where the substance being burnt is oxidized and the oxygen is reduced.

Step-by-step explanation:

A combustion reaction, such as burning a candle, is an example of an oxidation-reduction reaction, more commonly known as a redox reaction. In this process, the substance being burnt is oxidized as it reacts with oxygen, leading to the release of energy, often in the form of heat and light. The substance losing electrons is said to be 'oxidized', and the oxygen, which gains electrons, is said to be 'reduced'.
