Complete the following matching pair questions.  You need to draw the Lewis structures on a piece of paper for all the possible formulas before selecting the answers.  No need to send me the paper! Note:  All the numbers in the formulas are subscripts.

What is the mole of 2.50 L oxygen at 325oC and 83.2 atm?  The gas constant is 0.0821 L atm/ K mol.         (a)  0.128 mol               (b) 4.24 mol              (c)  0.236 mol               (d)  42.4 mol            (e)  7.80 mol

According to Gay Lussac’s Law: P is directly proportional to V P is directly proportional to T P is inversely proportional to T V is directly proportional to T no correct answer given

The metallic solid is KBr Ca Na2O S no correct answer given    

An 355 mL of a balloon filled with hydrogen gas has 848 torr at 75oC.  What is the volume of this gas if the pressure and temperature are changed to 375 torr and 64oC, respectively?  (SHOW CALCULATION in the space below).  Must show calculation to get credit!  Without calculations, you will get zero point, even if you get the answer correct.  DO NOT email me your scratch paper. (Hint: make sure you use the correct unit for temperature!)

According to the lecture, which of the following is part of Kinetic Molecular Theory for gases? Gas particles are close to one another. Gas particles do not attract one another. The average energy of the particles depends on the volume. Pressure results from collisions of gas molecules with other gas molecules All of the statements are not part of Kinetic Molecular Theory.

According to your lecture, the SO3 gas is responsible for
