HAPPY NEW YEAR! 

We have 2 weeks left before we start reviewing for the Mid Term. Remember that the Mid Term Exam is worth 20%. This is a big grade and I will be giving you review question HW to keep you up to date on this cumulative exam. DON’T WAIT UNTIL THE LAST NIGHT TO REVIEW FOR THIS.

This week we will begin our next topic–stoichiometry. Stoichiometry is a process chemists use to determine the amount of products or reactants and made or needed during a chemical reaction. I will be posting assignments for you to do and turn in by Friday. You may ask questions about the problems throughout the week to help you solve the problems. Again waiting to the last minute will be counterproductive.

Here is a copy of the Powerpoint notes to help fill in any notes you missed in class…

Here is a list of assignments for you to turn in on Friday.

HW1: Click here http://dbhs.wvusd.k12.ca.us/webdocs/Stoichiometry/WS1-MoleRatio.pdf and do all the problems.

HW 2: Click here http://dbhs.wvusd.k12.ca.us/webdocs/Stoichiometry/WS3-Stoich(Mass-Mass).pdf and do problems 1-8 only.

In class we will be working in groups, pairs and solo to really get an understaqnding of what stoichiometry really is. We will also work on a lab in the next couple of weeks as well.

Get ready!
