Propane gas (C3H8) and air enter a constant pressure combustor at 7 celcius and 1 atm. The mass flow rate of propane is 0.005 kg/min and 50% excess air flows into the combustor. What is the air-to-fuel ratio?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
