Question

10. When sulfur dioxide gas reacts with oxygen gas, sulfur trioxide gasto sulfur trioxide are produced, how maly mors of oxygen gas reacted Ex2732 & M=120.92 mol baas, sulfur trioxide gas forms. If 3.5.mer of b. If 16L of sulfur trioxide are collected, how many liters of oxygen were reacted, assuming the pressure and temperature are constant? c. If 4.5L of oxygen react with 6.0L of sulfur dioxide, how many L of sulfur trioxide wi form, assuming the pressure and temperature are constant? 11. If a container holds a mixture of nitrogen at 1100 torr and hydrogen at 0.45atm, what is the total pressure inside the container? 12. If argon is collected over water at 29°C and 1.25 atm, what is the partial pressure of argon? (7a) 2.3L 0: (75) 25.5g KCI: (8) 3.57g/L: (9) 121g/mol: (10a) 1.8mol; (105) 8.0L; (100) 6.0L: (11) 1.8atm; (12) 1.21am

Answer 1

10) a) 250269) + 026) ->250369 ) 2 moles of so, needs a mole of a 3.5 moles of sog needs 1*3.5 1.75 moles of Oz gas 118 moles of a gas b) al of so, requires Lofo - 16L of so, requires a 1x16 sl of O2 gas a) so is the limiting reagent. moles of są is equal to the moles of Soz. volume of sos formed = GooL - 11) pressure of We gav a 1100 likhy atm pressure of He gas 20.45 atm Total pressure a 10h47 +0.45 14897 atm 2 . 760 12) pressure of water vapor at qe = 30.0 forr F0.039 aibo · F0.04 aton Partial pressure di Argon = 1.25-0.04 F1:21 atm
