a) A 10.0 g sample of a mixture of methane (CH4) and ethane (C2H4) reacts with oxygen at 25C and 1 atm to produce carbon dioxide and water (liquid). If the reaction produces 520 kJ of heat, what is the mass percentage of methane in the mixture?

b) A mixture of argon and neon gases at 77C contains twice as many moles of neon as of argon. The mixture has a total mass of 50.0 g. If the density of the mixture is 4.00g/L, what is the partial pressure of the neon gas?

c) What will the final temperature be, of a mixture made from equal masses of the following: water at 25.0C, ethanol at 35.5C and iron at 95.0C?
