CHM 111L Spring 2010

Information Page

A copy of the syllabus for CHM 111L is here.

The MSExcel spreadsheets needed for the class are below.
For best results, click on the link and SAVE it to your USB drive, then reopen using MSExcel.
These spreadsheets will not change all semester, so you can download all of them at once, instead of waiting until you perform the experiment. What if you didn't bring your USB drive? Try emailing the file to yourself, so you will have a copy as a back-up.
The spreadsheet for the Spreadsheet Assignment (Lab 0)
The spreadsheet for the Basic Lab Techniques exercise (Lab 1)
The spreadsheet for the Physical Properties Lab (Lab 3)
The spreadsheet for the Solutions and Titrations Lab (Lab 5)
The spreadsheet for the Thermochemistry Lab (Lab 10)
The spreadsheet for the Gas Laws Lab (Lab 11)

Recitation and Lab Announcements

Thursday April 29, 2010
Turn in your Gas Laws lab report at the start of the lecture test (11:30)

Week 16: April 26, 2010
You will turn in your lab portfolio, then take the final exam in recitation (this is different than what is stated in the syllabus)--click here for the exam topic list. For the lab time, I will lecture about chapter 9 material to catch up to where we need to be.

Week 15: April 19, 2010
What to turn in: Thermochemistry lab (pages 5 and 6), the spreadsheet, and the formula page. Note that you will have to write an abstract for this experiment (click here for the abstract grading rubric--the file will open as a pdf file).

How to prepare for lab: To prepare for the prelab quiz, read the “Gas Laws” experiment, answer the prelab questions, and view the ChemPages modules on the

Barometer
Gas burner

You will also perform check-out.

Week 14: April 12, 2010
What to turn in: The “Molecular Structures and Shapes” lab report (pages 5-8).

What you need to do to prepare for lab: Read the "Thermochemistry Lab” (lab #10), answer the prelab questions, and view the ChemPages on the “Coffee-Cup calorimeter” and the “Thermometer”. Expect a prelab quiz. Heads-up: you will have to write an abstract for this lab, too. Details will be forthcoming.

Week 13: April 5, 2010
What to turn in: Pages 7-9 of the "Chemistry of Copper Lab." Weigh your copper and calculate the percent yield at the start of lab, then turn in your lab report.

How to prepare for lab: Read the Molecular Shapes lab (experiment 9) and answer the prelab questions; expect a prelab quiz. Be sure to keep current with the lecture material since we will be just covering the background for this lab in lecture at the same time.

Week 12: March 29, 2010
THE MIDTERM EXAM WILL BE IN RECITATION!! CLICK HERE FOR THE EXAM TOPIC LIST THAT WAS GIVEN IN LECTURE (March 23).

What to turn in: The Solutions and Titrations Report (pages 9-11, plus a spreadsheet and formula page).

What you need to do to prepare for lab: Read the "Chemistry of Copper" experiment and answer the prelab questions. Notice that in the reading for the lab, you will see examples of synthesis, decomposition, single replacement, and double replacement reactions. Expect a prelab quiz based on the reading, prelab questions, and the ChemPages modules on

"Filtration, Vacuum" (already should have done this for the alum lab)
"pH paper"

Week 11: March 22, 2010
What to turn in: The Alum report (pages 9 & 10). Also, you will need to write an abstract for the alum lab—CLICK HERE TO DOWNLOAD GUIDELINES SPECIFIC TO THIS ABSTRACT!! Be sure to look over the examples and rules in the lab manual's appendix for general information about abstracts.

J.	Double spaced	1
	Total points	50

What you need to do to prepare for lab: Read Lab 5 (Solutions and Titrations). This lab is normally performed over a two week period, but you will only do Week #1. To prepare for the prelab quiz, read the lab, answer the prelab questions, and look at the ChemPages modules on the following topics:

Titration
Buret
Flask, volumetric

Week 10: March 15, 2010
What to turn in: The Periodic Properties Lab (pages 11-14) AND two graphs assigned in lab Be sure to COMMENT on the periodic trends that you see.

What you need to do to prepare for lab: Read Experiment 4 (Alum from Waste Aluminum Cans) and answer the prelab questions. Please review the ChemPages module on "Filtration, Vacuum" since you will be using similar equipment in this week's lab (you may skip the part on "Connecting the trap" since you will not be using a trap, but you will be using a water aspirator, so pay particular attention to those parts). You will have a prelab quiz covering your readings from Experiment 4, the prelab questions, as well as the ChemPages module. Also, you will need to bring in a piece of aluminum can that has been cleaned/scraped of the outer plastic/paint coating. Using a piece of sand paper, steel wool, or a brillo pad works well. See the lab manual for details (step 1 of the procedure). Doing this procedure BEFORE lab will save you quite a bit of time...

Week 9: March 8, 2010
SPRING BREAK--NO LAB!! Be safe and catch up on your chemistry studying!!

Week 8: March 1, 2010
What to turn in: "Hydrogen Emission" experiment (pages 9-12) AND the calibration curve (Excel plot) AND the energy level diagram (use the graph paper at the end of the experiment). The calibration curve needs to have a formal title (include your name in parentheses), labeled axes, and the R²/equation of the line--if you made a "quickie" version in lab, that is not enough.

How to prepare for lab: Read “Periodic Properties”, answer the prelab questions, and view the ChemPages module on the “Gas Burner” (read the lab manual appendix on the gas burner, too). Expect a prelab quiz.

Week 7: February 22, 2010
What to turn in: The Physical Properties report including the RAW DATA and post lab questions (pages 5-7). You will also need to turn in the spreadsheet (and a formula page) for this lab. You will also make a graph of the class averages versus the concentrations of the standard NaCl. Please include an appropriate title (SEE PAGE TWO IN THIS EXPERIMENT!!!!), label the axes, and draw a trendline for the graph. If you have questions, please ask for help.

How to prepare for lab: Read the "Hydrogen Emission" lab and answer the prelab questions; view the ChemPages modules on

Spectroscope, handheld
Vernier scales (under Additional Topics in the Scales module)

Expect a prelab quiz.

Week 6: February 15, 2010
What to turn in: The Paper Chromatography lab report pages 7-9 AND the chromatogram.

What you need to do to prepare for lab: Read Experiment 3 (Physical Properties) and do the prelab questions. There are no new ChemPages modules to view and you will not have a prelab quiz.

Week 5: February 8, 2010
What to turn in: The BLT report (pages 13-15), spreadsheet, formula page. Be sure to use formulas for all calculated values on the spreadsheet.
How to prepare for lab: Read the Paper Chromatography experiment, answer the prelab questions, and view the ChemPages module for:

Chromatography, paper (Your experiment will be a little different because you will not use string to suspend the paper, but otherwise it is pretty much the same. Watch all parts of the module.)

You will have a prelab quiz.

Week 4: February 1, 2010
Turn in: Safety lab (pages 7 & 8) and the spreadsheet assignment (computed version, formula page, and the graph).

Prepare for lab: BE READY FOR A SAFETY QUIZ AND A PRELAB QUIZ. The safety quiz will cover the lab tour, the reading, and the video. To prepare for the Basic Lab Techniques (BLT) quiz: read the experiment, answer the prelab questions, and view the ChemPages for:

the balance
the volumetric pipet
standard bulb
graduated cylinder (100 mL)

Reading the text, viewing the movies (see bold text above to set the computer to watch the movies), and answering the questions should be sufficient for you to learn the material.

Material for your pre-lab quiz will come from the reading, the prelab questions, AND the ChemPages.

Week 3: January 25, 2010
You need to go to both recitation and lab this week. You will perform the safety lab and watch a safety video, check into lab drawers, take a lab tour, get assigned numbers for a spreadsheet assignment, etc. Starting this week, bring safety goggles (not safety glasses--the goggles must have a strap to keep them on your head) and wear close-toed shoes.

Week 2: January 18, 2010
Due to the Martin Luther King, Jr. holiday, there is no lab. Be sure you have the lab manual and goggles for next week's experiment!

Week 1: January 11, 2010
For this first week, there is no lab or recitation, but do get the lab manual from the bookstore, along with goggles and some type of device to save files from a computer (like a USB-drive).
