I wish everyone the best for 2015-2016 academic year.  You may have noticed a small change in your final grade as I lowered the weighting on the final from 150 points to 100.

You were a great group of students, all very capable and I know you will succeed at overcoming whatever challenges await you.

Cheers,

4Al +3O2 -> 2Al2O3
2Sn(OH)3 → Sn2O3 + 3H2O
4H2 + Fe3O4 → 3Fe + 4H2O
2Al + 3FeSO4 → Al2(SO4)3 + 3Fe

I noticed one student writing down questions for the class as she completed her homework.

 

GREAT IDEA!  If you don't do a question because you don't understand it let's discuss the question next class.

Stay up to date with your homework.

Our final exam will be comprehensive.  To raise your grade now and prepare for your final you are encouraged to review your tests with me.  This may require you to attend a tutoring session as we often do not have time during our regular class time.

Test corrections are encouraged as follows:

Students with test grades from 70 to 79% may write out any incorrect question(s) and explain the correct answer(s) in complete sentences to raise their grade to a maximum of 79%.

Students with test grades less than 70% will be permitted to retest on the same material with an averaged final score of no more than 79%.

to: All Students

I have recorded your grade for the first two assignments and our test Ch 1-4.

Dr. Renders

to: Chemistry 8am (P)

Our schedule calls for a test on Ch 1-4 tomorrow.  Please attempt all homework questions and be prepared to ask questions on material you are unable to complete.

Sincerely,
