Over the past week, we've focused mainly about the electron domain geometry and molecular domain geometry. First, we had to became very familiar with drawing Lewis structure in order to get our basic foundation down. We then practiced on finding out the polarity and dipole moment. It's pretty simple overall, basically we just find out the lone pair of electron around the central atom, then we can figure out how the atoms in the molecule are bending. Therefore it allows us to know which way the dipole moment is going by finding out the polarity bond between the outer atom to the central atom and which way they are pointing.
We spent about two days worth of class time doing both the balloon and gum drops activities, basically building a molecule ourselves. The balloons simply represent and explain the electron domain geometry, as well as the gum-drops activity shows us a visual representation of the molecular domain geometry. Later on the week, Dr. Finnan instructed to do the WebMo program which is simply a computer program that draws the dipole moment and shows the space filling molecule for us. It was a lot of fun! I enjoyed it a lot with the program because you get to physically handle the atoms yourself. We were also assigned to do the HotPot quizzes over the weekend, as well as finishing up the lab report for the WebMo. At that point, I was still very confused between the difference between the electron domain geometry and molecular domain geometry. As a result, on Saturday, I spent almost the entire day searching for online resources and struggling on the quizzes. I still am a little bit confused on some of the concepts but I am a lot better at it now since I spent pretty much the entire weekend studying for chemistry. The WebMo report took forever to finish. I spent about almost 5 hours trying to figure things out on Sunday for the lab report. It's a really simple concept, but the report asks you for a lot of things to do, such as drawing the Lewis structure, which means you have to draw the Lewis structure physically by hand. Then take photos of each one of them, edit, and post them unto your data table. It's really annoying. The most difficult part was typing the paragraphs for all of the thirteen molecules. I'm pretty positive about all of my concepts and answers, but it's just very exhausting trying to explain them typing thirteen paragraphs in a row. Finally, I even had difficulty converting my computer file so overall my entire weekend was taken away by chemistry.
I also have a math test tomorrow and an English project due on Wednesday, but I have not even started it because I was planning on finishing them up over the weekend then chemistry became a struggle to me. Everything to me right now is just a hassle. I am taking the ACT as well on Saturday. I have no time to study for it and any of my other classes. It really sucks. The good thing is that this week is actually the last week of football, which means by the time this week is over. I finally can have time to come home before night and finish up my studying for school.
