Semester2+Feb+16-20

Week Of Feb 16-20
__ Monday Feb 16 __-snow day

.............................................. Chem 112 Test on Wednesday Chem 111 1--I We went over the Quantum Mechanical Model of the atom. 2- I also did a Mega homework check ..no hwk other than to make sure you have a log key on your calculator
 * Tuesday Feb 17-** ................Chem 122 Test on Thursday of this week...

Chem 122 1-I went over the last type of calculation where energy produced is used to heat something up.

13.(You will add 13 to your page). #13 What amount ( mass) of methane undergoing complete combustion is required to heat 100.0 L of water from 5 degrees celsius to 70 degrees celsius?

Here is another question like #13 to try What mass of propane must be burned to heat 2.50 L of water from 10 degrees Celsius to 800 degrees Celsius?

2- there is an outline under the test review link that is like the Study guide at the end of your chapter. There are also some practise problems linked as a document too. Please remember that there are several practise questions at the end of the chapter. We will do some more group review to practise certain key types of questions for the test. .

solution for #13 worked out

Total energy [] [] Hess's Law [] Test Review Outline from The end of the Chapter Test Reviews Good Practise problems for thursday's test. Need to review combustion reactions?

Chem 112-Lab Day 1.........Reminder.... Test Remember that scientists will be tested in multiple choice or matching on your test. Scientist study document You will find that watching the utube will be helpful for studying. [] Here is a great site to practise your scientists []

Wednesday Feb 17-
Thursday __Chem 122__- 1-We will start a new unit, Ch 18.1 Collison Theory/Dynamic equilibrium/rate of reaction/Activation energy diagrams Please make up 1/2 page of notes on 18.1 and draw the diagram from p 547 into your notes. Include some of the labels from the other diagram a few pages earlier(.Please put the diagram from p 547(include catalyst) into your notes and include the labels from p 543 on it.) Do p 547 1 to 5 for friday and please get ready for the test tomorrow....do the practise problems......also do not forget that is adviseable to have read through the chapter twice. 2-You will work on more practise problems in groups for thursday's test. See the links from yesterday for help in doing a review for your test. [] __Chem 112__-TEST TODAY UNIT 1 -Please pass in fill in the blank practice sheet __ Chem 111 Due on Monday of next week: __

1--Quiz on metric and lab safety on thursday 2-We finished electron configuration and started half life calculations Please do U and Rn as practise tonight. Absent today?? Here are some helpful documents.. ...................... Text ques p 167 10 to 15 2-You received a worksheet with half life calculations on it. Please try question #7. There are some theory notes on this on the chem 111 info link at the side of this page. 3. You will a short assignment on ch 4 involving problem solving tomorrow. This will be due on Monday or Friday(bonus) Feb 20
