Science Through the Eyes of a Wolverine

 HAPPY NEW YEAR!

Here we go…the first semester Home Stretch!

We still need to finish our quest on stoichiometry. This will be an individual quest and will be held on Wednesday (1/7/09). We will review for the quest on Tuesday.

We will end the semester with some solution chemistry and review for the Mid Term Exam. DO NOT FORGET THAT THE MID TERM IS WORTH 20% OF YOUR FINAL GRADE.

A list of HW assignments are below and I will tell you in class the days they are due.

HW 1: Click here http://dbhs.wvusd.k12.ca.us/webdocs/Solutions/WS-Molarity.pdf and do all these problems.

HW 2: Click here http://www.chalkbored.com/lessons/chemistry-11/solubility-rules-chart.pdf and do all of these problems.

Also, click here if you want to look at some problems for review–I wonder if a problem like this might pop up on the quest? By the way the last 3 slides are for AP Chem–you don’t have to worry about them unless you are bored and want to try some extra fun.

Stoich Review

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!
