 CHEM 1200A & 1201A

        fall, 2020

CHEM 1200A/1201A online links

As AUM transitions to online classes for the rest of the spring semester, the following links will take you to material needed to continue the Chem II courses.   Note: the info below is for my courses only. If you are in another instructor's Chem II lecture or lab, you will have to follow their guidelines.  Online lectures will be posted the day/time classes were originally scheduled, then replaced with new lectures the following class. But they will remain on the instructor's YouTube channel until assessment (either test or essay) is given.
                                                  Modified timetable
​
Week beginning Mon 4/27 (sixth week after spring break)
​
Mon 4/27 online Test 10 on Chapter 11, organic chemistry, is now over. Grades to be posted asap
​
 
Wed 4/29  No new material. All labs due by tomorrow 4/30

​
​
Week beginning Mon 4/20 (fifth week after spring break)
​
Mon 4/20 online lecture continues Chapter 11 here.
 
Other chapter 11 online lectures here on YouTube channel. 
 
No new labs! But older labs after Lab 6 need to be submitted asap if not already done.
 
From last week: Lab: #33 Part B: This week's lab: #33 (week 10 lab). Analysis of a coordination compound. Data sheet here. Note: This is just a simple titration in which potassium permanganate reacts with the oxalate ligand on the iron compound which you would have prepared last week. Be sure to take note of the mole ratio in the balanced equation given in the lab book (equation 3 on page 33-2). Question B2 asks you to calculate the % of oxalate in the compound you would have prepared based on the titration results. Question B3 asks you to calculate the % oxalate from the iron compound's molecular formula. If your answers to B2 and B3 are close (within about 1%), that tells you the prepared compound is pure.
 
Wed 4/22 online lecture will conclude Chapter 11. 
​
Test 10 on chapter 11 will be posted on the web site (just like test 8) NEXT Mon 4/27 at 10:50 am
​
