Question

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

Answer 1

The temperature in the laboratory
            The position of the Bunsen burner
            The amount of air that mixes with the gas stream 
these can all have an affect on the intensity of the reaction. 

I hope I was helpful.

Answer 2

well the amount of air matters so ... seeing as there is no answer choices im going to say that the amount of air that mixes with the gas will cause the intensity of the reaction to increase or decrease so with that said i hope this helps :)
