3) Methane (CH4) is a short-lived greenhouse gas and climate pollutant. Carbon and hydrogen react to form methane, and it has an enthalpy of combustion of -890.7 kJ/mol. A) How many atoms of carbon and hydrogen are in 10 g of methane. (1 point) B) Determine the heat liberated when 1.5 kg of methane is burnt in air. (2 points) C) Assuming ideal-gas behaviour methane flows through a horizontal 5 cm ID pipe at 200 C and 100 kPa and a velocity of 40.0 m/s. Calculate Ek (W). (4 points) D) If the methane is heated to 250 C at constant pressure, what is AEK (W)? (4 points) E) What is linear velocity at the outlet and AE,, (W) if the pipe emerges at a point 150 m lower than the inlet at 200 C and 90 kPa.
