Equilibrium Constant Hasha
The question to do is on page 445 #6, hav3 fun ;9 If you don lik3 the top ques. try #2 on page 444.

Intro to Equilibrium Alissa
A mixture consisting initially of 3.00 moles NH3, 2.00 moles of N2, and 5.00 moles of H2, in a 5.00 L container was heated to 900 K, and allowed to reach equilibrium. Determine the equilibrium concentration for each species present in the equilibrium mixture; 2 NH3(g) <--> N2(g) + 3 H2(g) Kc = 0.0076 @ 900 K. From:[]

Le Chatlier's Principle Peter
Try this one out: pg 457 #1 What are the equilibrium shifts in each case? H=197 kJ 2SO3 <--> 2SO2 + O2 a) SO2 is added b) pressure is decreased (increase volume) c) increase pressure (add inert gas) d) temperature decrease e) O2 is removed

Intro to Acids/Bases Tiana
pg 532 #1

Ka, Kb, Kw Orlean
Pg. 556 #3
 * read "sample problem" pg.554-556*

Acidic and Basic Salts Ben
pg. 588 nr. 4
 * sample pg. 587

Henderson-Hasselbalch Equation Scott
sorry this took so long : Calculate the pH of a buffer solution made from 0.20 M HC2H3O2 and 0.050 M C2H3O2- that has an acid dissociation constant for HC2H3O2 of 1.8 x 10-5. the solution to this question is on : http://chemistry.about.com/od/acidsbase1/a/hendersonhasselbalch.htm (Hey guys, how come the question uses the wrong value for A-? What did you get as the answer? pH=4.14? -Conrad)

Theory of Titration Jia Ha
pg599 25ml of 0.10m/l HBr is titrated by 0.10m/l of NaOH what is the pH at the equivalence point?
 * 1.

Titration Calculations Sakina
pg 607 #5 Is the textbook answer for this question correct? What is everyone else getting for this? -andy

Titration Curves Andy
Draw a titration curve for the reaction of a weak acid and strong base.

pg 511 #3 examples on pg 510-511
 * Entropy and Equilibrium Reilly**

Buffers Nura
We might be learning more on the topic but here is a question based on what Leslie taught today. p.620 #1,3 and 4

Ksp Danielle
pg 486 # 1 (see examples pg 485 - 486) Calculate the solubility of silver iodide at 25 degrees Celius. The Ksp of AgI (s) is 1.5 x10^-16 at 25 degrees Celius.

Balancing REDOX reactions Qingda
pg 673 3 b) i got 4h2o + mn2+ + 5hbio -> 5bi2+ +Mno4 + 8h+

Galvanic Cells Vlad
I am not sure if we are going to learn anything else about Galvanic Cells but the question below is good for general knowledge Page 700. Practice Question #6 (a)

Electrolytic Cells Claire
pg. 735 # 1, 2

Electrolysis Manuel
pg 736 # 5 759 # 1, 2, 3, 8, 10. You may think that this is a lot of work but actually, It isn't and you'll see why once you get to pg 759

Faraday's Constant Conrad=asian+gangsta
pg 749 # 1, 2, 3

Hydrocarbons and Chirality Simone
p.21 #7 and 8 are good practice questions
