[] Enthalpy/Enthalpy change

Chem 112-Today we will go over sections 1.1, 2.1 and 2.4. You will be working on some theory questions p 11 1 to 4 p 25 #18 p 22 draw diagram into your notes and write all darkened definitions. p 42 1 to 8 and p 55 28 to 34 For R 80 to 81 write the five rules that you feel are the most important. We will also go over two more types of separation. Chem 111-We will spend half of the class doing a chromatography mini lab and the other half of the class will be spent in the lab doing an activity / or you will be researching lighting a bunsen burner lab safety rules as well as R80-81. You will receive an assignment on the scientists..I will also explain the assignment involving the scientists who worked with the atom. p 128-129, p 144 contain the names and contributions of the scientists. The scientist name as well as their contribution have to be included in a creative way to help one study these scientists. This is due on monday of next week.

Feb 8-Tuesday Day 4 LAB SAFETY VIDEO []
Chem 122- Today we will review enthalpy and work with total energy and heating and cooling curves. We practised drawing various curves. Homework: handout #1. You will complete your group work. I also reviewed molecular naming. We had some people away today so I did not go over the questions from last night with period 3. We did not quite complete the group work yet either. I f you were missing the following doument summarizes the work we did today.(sorry for spelling error)

Chem 112-Since I did not have time to overview 1.1, 2.1 and 2.4 yesterday, I will overview them today. We will also go over some metric conversions from the worksheet. We went over the last part of separating matter. During the last 15 minutes half of the class will do a lab safety exercise. The other hald will read over lab safety and bunsen burner information. They will write down ten important lab safety tips. Assigned work: p 47 11 to 17, p 87 top #2 all Chem 111-After the chromatography mini lab is done, you will be lighting bunsen burners in the lab and doing a safety assignment. REMINDER: COURSE INFO FORM MUST BE SUBMITTED BEFORE YOU CAN DO LABS. You will also be signing a contract(tomorrow). I will outline lab set one for you. Please note that the homework will be linked below for the days that you are in the lab. Lab Set One Lab 1/5 Metric lab-This lab involves working with measurement af area, finding the density of a shape and some challenging conversions Lab 2/6 Elements versus Compounds-This experiment involves using heat to break down compounds. You will find that it has a flaw in terms of trying to break down all compounds. You will become an expert at using the centigram balance. Lab 3/7 Candle Lab-This lab involves making observations and trying different techniques for dealing with candle wax combustion. Lab 4/8 Separation of Matter-This experiment involves using the varation methods for separating matter to separate the components in an unknown mixture. Acuracy will be very important in this experiement.

**Feb 9-Wednesday Day 5-Chem 112 Quiz on metric/lab safety on thursday**
Chem 122-I finished solution enthalpy and assigned #25, 26. We did more work with heating and cooling curves. I fully labelled a complete curve for water with formulas, potential energy, states, kinetic energy. Please do #2 abd 3 from the handout. Do not forget about the assignment. Here ia document showing the answer to #1 from the worksheet.

Chem 112-We will spend time today going over the Periodic Table. We will be reviewing properties, symbols(2.2), Mendeleev, Dobereiner, arrangement of elements, the temporary naming scheme, periodic law, metals, non-metals and metalloids(6.1) and the family names (6.2 start). Assigned work: p 52 #20 to 27 and p 160 1 to 7. Today I will give you information on an assignment involving the scientists who worked with the atom. p 128-129, 144 contain the names and contributions of the scientists. The scientist's name as well as their contribution have to be included in a creative design. It should be able to be used to help one study these scientists. This study device or aid is due next monday During the last 15 minutes half of the class will do a lab safety exercise. The other half of the class will read over the lab safety and bunsen burner information. They will write down ten important lab safety tips. Coming soon....There will be a mini lab on chromatography on friday. We will be lighting bunsen burners tomorrow. Chem 111-NO CONTACT LENSES/OPEN TOED FOOTWARE or nylons. You will start lab set 1. Each day you will do a different experiment for the next four days. **Please have your course information sheet(signed) with you**. I will also remind you that the list of homework to be done during lab set one is posted online for your class under the link below.

Feb 10-Thursday Day 6- Dance tonight -no homework
Chem 122-More work with heating and cooling curves. You and a partner will work on an ethanol heating curve. Assignment: Due on tuesday: Period 2-->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.(period 3 had different numbers)

Chem 112-Today there will be a quiz on lab safety/metric conversion. You will spend half of the class lighting a bunsen burner. While half of the class is lighting the bunsen burner that other half will work on p 111-113 #15 to 20and p 119 25 to 33 We will light the bunsen burner tomorrow...instead and finish the work from yesterday on finding the ten most important safety rules and reading over the info. on lighting a bunsen burner.

Chem 111-Lab Day 2 Scientist Creative Assignment Due tomorrow.

Feb 11-Friday Day 7
Chem 122-Assignment Due today Hess's Law today Please do all of question 8 from the handout. Chem 112-You will spend half of the class doing a chromatography mini lab. The other half of the class you will practise lighting a bunsen burner. I will give you a vocabulary review sheet that is due on the day of your test. You will also receive a topic review sheet. Chem 111-Lab Day 3 Do not forget the assigned work that was given out on tuesday. This includes an assignment.
