  1. Unit 3: Kinetic Molecular Theory and States of Matter Gases and Their Behavior Day 2

  2. Gases and Their Behavior, Day 2 Daltons Law of Partial Pressures 3 Equations can be used … What is the total pressure in atm of a gas mixture that contains 1.0 g of H2 and 8.0 g of Ar in a 3.0 L container at 27oC? Calculating the Molar Mass from P,V,T What is the molecular mass of a compound when a 0.100 gram sample exerts a pressure of 70.5 mmHg in a 256 mL container at 22.3oC?

  3. Gases and Their Behavior, Day 2 Gas Law Stoichiometry Airbags are filled with nitrogen gas created by the following decomposition of sodium azide: 2 NaN3 (s)  2 Na (s) + 3 N2 (g) The bag has to inflate to a high pressure (say 829 mm Hg) and has a volume of 45.5 L. At room temp (22oC), what mass of NaN3 should be used?

  4. Gases and Their Behavior, Day 2 Gas Law Stoichiometry The Ultimate Stoichiometry Problem: 2 Li (s) + 2 D2O (l)  2 LiOD (aq) + D2 (g) What will the pressure be of the D2 that can be captured in a 1450 mL flask at 22oC from 0.125 g of Li metal in 15.0 mL of D2O (d=1.11 g/mL)

  5. Sample AP Question 2004 Exam Directions Write the formulas to show the reactants and the products for any five of the situations described below. In all cases a reaction occurs. Assume solutions are aqueous unless otherwise noted. Represent substances as ions if extensively ionized. Omit formulas for any ions or molecules that are unchanged by the chemical reaction. You need not balance the equations. (IV-79) a). Excess concentrated sodium hydroxide is poured onto solid aluminum hydroxide b). Acidified solutions of iron(II) sulfate and potassium permanganate are mixed c). A sample of 2-decanol is burned in excess oxygen gas. d). Solutions of dilute sulfuric acid and strontium hydroxide are mixed. e). Solutions of silver nitrate and sodium dichromate are mixed. f). A piece of calcium is heated in an atmosphere of pure nitrogen. g). Dilute potassium hydroxide solution is poured into dilute nitrous acid solution. h). Solutions of tin(II)nitrate and cobalt(III) nitrate are mixed.
