I want in! Question 16 5 points Save Antwer in the following combustion reaction of methane gas (CH4) with oxygen is given. Methane, C H 4, reacts with oxygen to produce carbon dioxide, water, and heat. If you put a porce­lain pot lid in a meth­ane flame, a black de­posit of soot will not form, as the car­bon in the meth­ane burns com­plete­ly. You can calculate this enthalpy value yourself if you know the starting molar quantity of the fuel, as well as the heat change that occured at constant temperature and pressure. This is equivalent to saying that the enthalpy change for the combustion of one mole of methane is .
