Homework Help: Chemistry: Bunsen Burner Lab

Posted by Cicilia on Monday, February 6, 2012 at 9:48pm.

Hi! I have recently completed a bunsen burner lab and need help with a few conclusion questions:

1) What kind(s) of energy is released by the reaction of fuel and air in this system?

2) Which part of the Bunsen flame is hottest? How do you know?
->I researched it and know the top of the inner cone (non-luminous) part is the hottest, but my lab group did not complete the experiment, so I don't know exactly why this is so

Thanks in advance!

Isn't heat the energy that is released?
Also light energy is released.

Yes, the top of the inner cone is the hottest. That is the point at which the maximum reaction is taking place.
CH4 + 2O2 ==> CO2 + 2H2O
