2-25-10

The one question we did today in class:

(rate of effusion H)/(rate of effusion O)= Squareroot(O's molar mass)/Squareroot(H's molar mass)

AKA: H has a higher rate of effusion, because O is bigger.

Wednesday of Next week is when the test will be

The Homework is Pg. 390: 7-11, 18-26

    Lab was moved back to Monday of next week, be prepared guys.

    Also, study up for the chemistry test this weekend, cause we also have a trig test on wednesday that will require time for studying too!

    remember that if you blogged on Matt johnsons post then you will receive a point. Also, remember how to convert units of pressure. a good guide is on table 1 on page 364
