4/13 Chemistry update and homework due 4/20

Hi folks,

Today we spent some time getting familiar with how energy works within reactions. We will spend a bit more time with this next week as well.

Homework for this week is to:

Read pages 279 - 293 in the text

Do Questions 17 - 33 on page 302

Also:

This is a great and fun way to get a handle on stoichiometry and limiting reagents.  Spend some time with this site.  I highly recommend starting with the sandwiches part, then moving to the molecules part.  After that, try your hand at the game.  10 point of extra credit if you send me screen shots of your scores after doing each level of the game.  Three screen shots in all, one for each of the three levels.  You need to score at least a 4 out of 5 stars for it to count.

Have fun and good luck!
