Which of the following affects the intensity of the combustion reaction of a bunsen burner?

the temperature in the laboratory
the position of the bunsen burner
the amount of air that mixes with the gas stream

"The amount of air that mixes with the gas stream" is the one among the following choices given in the question that affects the intensity of the combustion reaction of a Bunsen burner. The correct option among all the options that are given in the question is the third option or the last option.

The amount of air that mixes with the gas stream affect the intensity of the combustion reaction of a Bunsen burner.

Correct answer choice is:

The amount of air that mixes with the gas stream.

Explanation:

A combustion reaction is a reaction that occurs when a substance reacts with oxygen, releasing energy in the form of heat and light. The Bunsen burner is commonly used in school laboratories to heat chemicals. Its fuel is natural gas, which is almost pure methane, CH4. The amount of air or oxygen mixed with the gas stream affects the completeness of the combustion reaction and fewer air yields an incomplete and cooler reaction.
