Methane (ch4) is burned completely with the stoichiometric amount of air during a steady-flow combustion process. if both the reactants and the products are maintained at 25c and 1 atm and the water in the products exists in liquid form, determine the heat transfer from the combustion chamber during the process. what would your answer be if combustion were achieved with 100% excess air?

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
