Chemistry Recording 12/20 Quantum Electron Configuration
12/20 Chemistry update and homework due 1/10
Hi folks,
Today we spent time on one of the more confusing concepts of chemistry. The confusing concept of the quantum method of electron configuration. This is quite tricky since it is something that is very hard to visualize. Once you do a few, however, it gets fairly simple. Homework this week will be to do quite a few of these configurations.
Homework due 1/10 is to:
Write the quantum electron configurations of
a. Na b. P c. Ar d. Rb e. Ru f. Sb g. Po
Read Chapter 5 pgs. 133 - 152
Answer Review Questions Pg 166 and 167 #'s 13 - 17 and 22 - 37

12/13 chemistry update and homework due 12/20
Hi folks,
Today we went even deeper into the periodic table. We covered the trends of ionization potential and electronegativity. We also spent more time on valence electrons, how atoms bond and Lewis Dot diagrams.
Homework this week is to do the attached .pdf form. It's basically a logic puzzle where you will be putting together the periodic table of elements on and alien planet! Feel free to ask any questions that come up and have fun with this!

Chemical Symbols
Hi folks,
Turns out there's a typo on the chemical symbols I wanted you to memorize. Don't worry about An. It's a typo and doesn't exist. Sorry about that.

57-62
Answer Review Questions #'s 23-32
Answer the following questions
1. How many protons, neutrons and electron are in the following atoms
a. Aluminum
b. Antimony
c. Strontium
d. Oxygen
e. A positive ion of Gallium
f. A negative ion of Barium

11/22 Chemistry Update and homework due 12/6
Hi folks,
Today we spent a bit of time looking as some very general definitions for chemistry. We also spent a bit of time looking at some of chemistry's early history. We also did a little historical lab of our own today. In the spirit of early chemists, I gave groups of student mixtures of sand, salt, Cherrios and styrofoam. Their task was to separate the mixture into all 4 of the component parts. They could only use each separation procedure once. It was a bit of a challenge but every group was able to figure out their own procedures.
Homework for 12/6 is to:
Read pgs. 37-56 (Don't worry about the naming section, we'll get into that in much greater detail soon.)
Do Exercises starting on pg 65 #'s 2 - 8, 11, 13-15

Read the text from 89 - 92
Do Review questions pg 95 #'s 27 - 34
Do Exercise questions on pg. 98 #'s 28 - 31 and 33-34

11/8 Chemistry update and homework due 11/15
Hi folks,
Today we spent a bunch of time working with these recent concepts mathematically. We also undertook a fairly massive and complex lab. The goal was to find the specific heat of lead.
Here are a few websites for the concepts we've been covering the last two weeks. They do a nice job giving examples of the problems and solutions. After taking a look at these, I hope you all feel much more comfortable with these types of problems. As always, DON'T HESITATE, to contact me if you have any questions.
http://www.chemteam.info/Thermochem/Time-Temperature-Graph.html Go through the steps and try to answer the problems. Then feel free to look at the answers.
Last but not least, finish all the questions on the sheet we used in the lab.

11/1 Chemistry update and homework due 11/8
Hi folks,
Today we started to look at heat capacity, specific heat, and change in temperature. We did a lab where we separately heated 100 ml of water, rubbing alcohol, and vegetable oil, as well as 200 ml of water and measured the temperature every 30 seconds. After the lab, we took a look at all three lab groups results and discussed what we saw. We also introduced the new formula q=mCpΔT which will be haunting us for the next couple of weeks. q = heat, m = mass, C = Specific heat and T= temperature. The funny triangle thing is the greek letter delta and means "change in".
Homework for this week is to do a lab report for today's lab.
For the data analysis portion of the lab report, create one graph with four slopes representing the four materials that were tested in class. So, this graph would have a line for water, rubbing alcohol, vegetable oil and 200 ml water.
Also by using the change in temperature for each liquid and the formula above, determine the amount of heat each substance absorbed in 5 minutes. Remember, you'll need to use the formula for density to find the mass for each material.
For the conclusion, be sure to relate it back to your hypothesis and include the order in which the materials changed in temperature, as well as the order in which they absorbed heat.

Fwd: 11/16 Chemistry update and homework due 11/30
Hi folks,
Sorry this took so long to get this out to everyone.
This week we took a look at the five phases of matter, phase change and the relationship between heat, temperature and phase change.
Homework this week is to answer the following questions and do the enclosed worksheet .pdf.
1. What are the five phases of matter?
2. Describe what happens, molecularly, as a solid increases in temperature and changes phases. Be sure to include a description of the bonds and how they change over the process. Also, what would temperature be doing over time as this substance changed temperature.
3. List the states of matter from least amount of kinetic energy to greatest amount of kinetic energy.
