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

  2. Gases and Their Behavior Gas Pressure and Conversions: Really . . . Boyles Law: Thought experiment: sealed syringe full of air Formula, parameters, real-world understanding Charles’s Law: Formula, parameters, real-world understanding

  3. Gases and Their Behavior Combined (General) Gas Law Real life situations usually involve many changing variables Avagadro’s Hypothesis Relationship between volume and amount of gas Volumes can be used stoichiometrically N2 (g) + 3H2 (g)  2NH3 (g) If you begin with 15.0 L of H2, what volume of N2is required? (assuming measurements are made at same T and P)

  4. Gases and Their Behavior The Ideal Gas Law Pivnert …. Density of Gases http://www.youtube.com/watch?v=d-XbjFn3aqE http://www.youtube.com/watch?v=1PJTq2xQiQ0 Formula, practical implications Calculate the density of CO2 at STP.

  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.
