**Sept 13-Monday Chem 112 Quiz on metric and lab safety on wednesday**
Chem 122-I went back and finished solution enthalpy from last week. You had previously done #25. We did #26 together. Today we practised some heating curves. I fully labelled a curve for water with formulas, potential energy, states, kinetic energy(we did this on friday). I changed what we did today to practise some heating and cooling curve sketches, then I assigned all of #1 from the handout.

THIS WILL BE DONE TOMORROW->You are to do the same for ethanol(grain alcohol). You will then use the mass to find total energy. The mass you need is 1.52 g order for you to work out all five calculations for the cooling curve. I did not give you the starting or finishing temperature. so if you happen to check this site out, assume the mass is 1.52 grams and that the starting temperature is 102C and the finishing temperature is -134C. I gave the bp and mp to you in class bp= 76C mp= -114C. You were given more time to complete the group work that you did last week. You will receive a handout with problems on it.

Chem 121-We will go over cis and trans isomers(geometric), cycloalkanes as well as isomers of alkyl groups.Do. P 707 #25 and fix any from the weekend worksheet. If time permits we will go over #3 to 12 on p 699 to 701 If time permits we will start aromatic hydrocarbons. This family will require quite a bit of study as this is the only way you will know their names and structures. You received a worksheet to practise all of the families we have done so far. Please do all of the odd numbered questions(this will be assigned tomorrow). We will be starting some project work this week. There will be a test on Ch 22 next monday. Your drawings of the C8 isomers(all 18 of them) with names is due wednesday.

Chem 112 P4,P5- Today we looked at the Quantum mechanical model of the atom. We looked at indicating the energy level, orbital and number of electrons in a partcular orbital. I introduced the diagonal rule to students. This section can be found in the textbook from page 164-166. Write the electron configuration for the following atoms. Period 4 was assigned Pd, Rn, U for homework. Period 5 was assigned Rn, As, Ag, U for homework. We checked over the work from last week p55 #28 to 34 and p 160 #1 to 7. There will be a quiz on metric on wednesday.

Sept 14-Tuesday Chem 112 - Test Next Tuesday Sept 21 on Unit 1 Chem 121-Test on Ch 22 Next monday Sept 21
Chem 121-We will spend more time on aromatics, and then we will have gone through all of the families for organic that lead up to next week's test. We went over the answers to sheet 1 at the start of class and then after the notes were given on aromatics, you were assigned sheet 2 and the left side of a new handout. These should be completed for tomorrow.

We will be starting group work tomorrow and we will also do some Petroleum/Natural gas Chemistry from 22.5. You will be given time to read through 22.5 and do a guided reading exercise. this is to be completed for thursday. This will help you make up some notes on this section. We will go over some of the worksheet from yesterday. This worksheet is to be complete for wednesday.You found out who is in your group for your organic project. You will note that the details of this project are given in the Chem 121 link. an enlargement of the work from section 5 is also be contained in the link.

Chem 122-Today we will do some more practise with heating and cooling curves. The ethanol curve will be assigned that was outlined under yesterday's work.You will get some additional practise work for the heating and cooling curves and the next few topics we cover as the textbook does not contain enough practise on this topic and the remaining topics in the unit. Please do, #22a, b off of the worksheet for tomorrow. Assignment: due this thursday: Find the total energy required to cool ethanol from 102oC to -134oC. The mass you are cooling is 1.52 g. Show your work and units for all five calculations for the cooling curve. The bp= 76oC mp= -114oC. Circle or highlight the values that you obtained from tables. The specific heat values for ethanol steam is 0.85 J/g oC and frozen ethanol is 1.05 J/goC. Please include a well-labelled cooling curve with PE, KE, formulas and states on it. Your final answer should contain the proper number of significant digits.

Chem 112-You will be given a test outline tomorrow. This is linked below if you should misplace the copy that I give you. Today you will get the opportunity to do a lab safety exercise in the lab for half of the class. Please review R 80-81(this was assigned last friday) and be aware of the fact that there will be a quiz on lab safety and metric tomorrow. I will also give you an additional metric conversion practice sheet(This is linked below for those who need extra practise) Reminder: The Creative assignment with Scientists is due today. p 47 11 to 17 was also assigned ...but I forgot to tell you this. You will work on 6.1 while half of the class is doing lab safety. Test Reviews

Sept 15-Wednesday
Chem 122- today you will work with Hess' Law. It will involve working with chemical equations that are dealt with mathematically. I will assign #8 for tomorrow from the organge handout. Reminder: Cooling curve on ethanol is due tomorrow. Chem 121-Today you will receive some information on the project for organic chemistry. You will be given some planning time for this starting tomorrow and then we will go over the answers to the worksheet. You will get half of tomorrow's class and half of friday's class as well. Then next tuesday you will get half of the class to finalize plans for your project. We will start presenting next thursday. We will do some group review of organic ch 22 for the next two days.. Please do the right side of the organic practise sheet for friday. Here is an approximate schedule for project planning time.


 * Wednesday ||  Project topic decision made  ||
 * Thursday ||  ½ class for project planning ½ class- group review  ||
