Each of the main engines on the Space Shuttle burned liquid hydrogen (H₂) and liquid oxygen (O₂) at a mass ratio of 1 kg H₂ to 6 kg 0₂. a) Write a balanced chemical equation for the reaction. If there is excess O2, the products are H₂O and O₂. If there is deficient O₂ the products are H₂O and H₂. Assume that there is no dissociation of the products. b) The fuel and oxidizer pumps increase the pressure of the H₂ and the O₂ to 20 MPa. The oxygen and hydrogen enter a pre-burner that increases their temperatures to 900 K; these gaseous reactants at 900 K then enter the combustion chamber. If the temperature in the combustion chamber is 3.400 K. what is the heat transfer to or from the combustion chamber in kJ per 1 kil ssume that the combustion process happens at n the combustion chamber. Find the adiabatic c) a constant pressure. Now assume that there flame temperature.
