Questions 41 and 43 have been answered but I'm having a hard time relating the one I need(42) to those. I am stuck on part c: for a given sample of CH3 OH, the enthalpy change is 25.8 KJ. How many grams of H2 gas are produced? and d: How many KJ of heat are released when 50.9 g of CO gas reacts completely with H2 to form CH3 OH at constant pressure?
