Chapter 11 Molecular Composition of Gases pp. 332-355

HW. #1: Outline Chapter 11 pp333-346, read figures 11-1,2,3,4 copy Table 11-1. Do Practice problems p. 343, 344, 345, 346

HW #2: Finish calculating R for kPa and mmHg. Study packet from Chapter 11 and do problems on pp. 357 on Ideal Gas Law # 16, 17, 18 click here for answers

HW #3: Molar volume and gas density, then p. 357 #9, 10, 11, 12,13,14,15 all the a & b if time allows do the rest of each. click here for answers

HW #4:Outline rest of Chapter 11 pp347-354, and Practice problems p. 348, 349, 350, 355. Problems on Stoichiometry p 358: 23, 24, 26, 27, 28, 31,34, Effusion and Diffusion # 39 and 41, Mixed Review p. 359 45, 47, 48 50 click here for answers.

NOTE: worksheet corrections
1. Gas Laws- Molecular Composition of Gases Molecular composition(answers)
#6 The reaction between ammonia and oxygen yields nitrogen monoxide and water. This question is like the webassign #9.
#7 the answer for moles is .0139 mole H2
#11 The answer I get is 6230 g/mol.
2.Molecular Composition of Gases worksheet (most of these vol-vol just use the ratio).
Vol.-Vol #4 b. answersould be 7.5 L
mass- vol #2 44.5 L
Ideal gas Law a.0.431 L

Labs:
Determine the molar mass of Butane. Butane Lab Lab report will include %error.
The reaction of a metal with HCl Mg and HCL NOTE: data for Mg + HCl lab report, use .086 g for Mg, 85.6 ml wet gas, 750 mm Hg and 21 C for water and 24 for air unless you got your own data.
Reports: Title, purpose, include any equations (draw the exchange of electrons and label oxidation or reduction) or reactions, calculation include % error using calculated MM and actual MM (butane lab only)
