Hydrogen (h2) 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 25°c and 1 atm and the water in the products exists in the liquid form, determine the heat transfer from the combustion chamber during this process. what would your answer be if combustion were achieved with 50 percent excess air?
