This page has all of the required homework for the material covered in the fifth exam of the first semester of General Chemistry. The textbook associated with this homework is CHEMISTRY The Central Science by Brown, LeMay, et.al. The last edition I required students to buy was the 12th edition (CHEMISTRY The Central Science, 12th ed. by Brown, LeMay, Bursten, Murphy and Woodward), but any edition of this text will do for this course.
Note: You are expected to go to the end of chapter problems in your textbook, find similar questions, and work out those problems as well. This is just the required list of problems for quiz purposes. You should also study the Exercises within the chapters. The exercises are worked out examples of the questions at the back of the chapter. The study guide also has worked out examples.
These are bare-bones questions. The textbook questions will have additional information that may be useful and that connects the problems to real life applications, many of them in biology.
Initial | Final | |
---|---|---|
P | 2 atm | P2 |
V | 5 L | 2 L |
T | 293 K | 293 K |
n | n | n |
= 0.416 moles
P2 = (0.416 moles)(0.082 L-atm/K-mole)(293 K)/(2 L)= 5 atm
Ni(s) + 2HCl(aq) → NiCl2(aq) + H2(g)
If the H2 is collected over water at 22 °C and takes up a volume of 180 mL with a total pressure of 740 torr, how many grams of Ni have been consumed? The vapor pressure of water at 22 °C is 19.83 torr.CH4(g) + 2O2(g) → 2H2O(g) + CO2(g)
How many liters of methane gas at 180 °C and 3 atm are required to react with 10.0 mole of oxygen gas in this reaction?
