Update for 1-19-2017

Due to the fact that I was administering ES Lab Practicum today, no additional work is being assigned, other than those that were assigned on Wednesday:

Regent Chemistry 1:        

• HW #19 Worksheet - Conversion between Mole and Mass & HW #20 (Due Fri):  Worksheet - Conversion between Empirical & Molecular Formula will be DUE TOMORROW.  I will give you time in class tomorrow to finish HW #20 worksheet after the lesson.

• Quite a number of you seems to be having trouble writing ionic compound formula, I am posting the Powerpoint for that lesson here so you can download and review it.
• Reminder:  Last Day of the Semester is TOMORROW!
  
Earth Science 1:         
• As of now, some of you still have not complete Quiz #6 (which took place on Wed.).  If you missed it, tomorrow is the last chance for you to make-up. 

• HW #21 (Due Thurs.):  Worksheet - Water Cycle, Infiltration & Run-offs will be due tomorrow if you haven't submit it yet..
• Reminder:  Last Day of the Semester is TOMORROW!
