2) If 25.0 g S (molar mass = 256.56 g/mol) is made to react with 2.0 L O at 30 C and 1.0 atm, what is the maximum amount (in grams) of SO3 produced? S (s) + 12 O2 (g) 8 SO3(g) (6 pts.) 3) A mixture of He and O2 is placed in a 4.0 L flask at 35 C. The partial pressure of He is 1.5 atm and the partial pressure of O2 is 2.5 atm. What is the mole fraction of O? (6 pts.) 4) The internal energy change (AE Sys) for a system is -65.0 kJ when it gives off 45.0 kJ of heat. How much work has to be done in the process? (4 Pts.) 5) Calculate the amount of heat (in kJ) required to raise the temperature of 15.0 g of water from 35.0 C to 75.0 C? (Cs, water = 4.18 J/gC) (4 Pts.) 2) If 25.0 g S (molar mass = 256.56 g/mol) is made to react with 2.0 L O at 30 C and 1.0 atm, what is the maximum amount (in grams) of SO3 produced?
