Today in lab we wrapped up loose ends by weighing our copper and working on the equations linked with this project. Overall I found the lab to be a great hands-on experience with what we learned in class.

Amazing Way to do Stoichiometry
Marie found this online and showed it to everyone and I just figured I would spread the news. The method is called the Magic Number Method and it is a great way to check your work since the process is twice as fast as doing Stoichiometry the regular way. Absolutely brilliant!!

Just searching around on Google and found this pic for solubility rules. Wish I had it for the test but at least I have it for the final.

The Labs
Here's a few pics from the two land we did for this unit. I really enjoyed these labs as they showed that chemical reactions actually happen and they are not just on paper
Feeling Ok after the test
I've heard from a lot of people that the test was really easy for them. That they were really confident with the test, I however wasn't so comfortable on the test. I had trouble getting in the groove of the test but at least it's over now so... I guess that's a plus.
Anyways,

Two more Crash Course vids, I will admit that they are a bit more confusing than usual but it's still a great crash course when the test comes around. (see what I did there...)
Anyways Happy Thanksgiving.

My Disorganized Mess
These are just pics of my work from yesterday, in prep for this test. I know they're messy but I assure you my work on the test was even messier.

Afternoon after the Test
Whew...that test was really rough, as most of my colleagues will also agrees. I don't think anyone, at least to my knowledge, finished before the hour. I was working the problems at the extent of my pace and I still had questions unfinished (usually I finish with time to spare). But all in all, I am glad it's over with and I am ready for the chapters to come.
Though I know its a little late here are some links to videos that explain percent composition. I found these to be dry for what they are worth but they get the job done.

Ehh...
Yesterday we had our first quiz for the unit and to say the least it was rough. I think I did okay, but the lack of questions on the quiz worries me since each question was worth more. Overall, I hope that the next few lessons won't be terribly bad.

Remember This
Though this picture doesn't account for converting moles and Volume at STP, this is a really easy way to remember the conversions. All you need to know is what number you're using and if you're going into or out of moles. Divide In, Multiply Out. (DI-MO)
Hope this helps,

Buckle Up it's gonna be rough!
Let's just say the last pre-test was rough. For the last few pre-tests, I knew (to a degree) what I was doing, I could always remember (again somewhat) what we learned in Physical Science. This one was the first test that covered material not covered in Physical Science. To be honest it's a little nerve racking but I'm ready to take on the challenge. Also, on a side note, I'm rather enthusiastic for not doing a lab for this unit. It means I can focus on studying the material.

Overview of Sig Figs
What I understand of Sig Figs is basically that they are all the numbers represented when a number is written in scientific notation. Trying to remember all the rules of whether a number is significant or not is a little too much to think about converting it to scientific notation is a lot easier.
DFTBA
As for math functions, sig figs get rather confusing, all I can say is remember that rounding is always to the least accurate number and that the least accurate number in adding (or subtracting) is the one with the least decimals while the least accurate number in multiplication (or division) is the one with the least sig figs. Other than that, remember states of matter, types of mixtures, and nomenclature. That should be it for the next quiz.
Also these link will help. The bottom two are a little elementary but they explain the topic quite nicely.

Pre Test
We had our pre-test and I'm feeling decent for this next chapter. I couldn't remember how to add and subtract sig figs but I think I rembered how to figure out how sig figs were in a number... maybe. Other than that this will be an interesting chapter.

Summary over our Unit
First off -or last off, I guess- we took our unit test for radioactive decay and atomic structure. I think I did well but maybe not good enough. My grade in the class plummeted after the frontier chemistry project and since I have struggled to pull it back up. The unit wasn't to confusing as, at least for me, the math wasn't to difficult as I have encountered these problems in other classes. What got me on the test were a few specific questions. I know I got at least one polyatomic question wrong as I decided it was to my best interest to study the other parts of the unit. I guess this turned out to be a bit of a mistake. I really should have studied those a little more. Oh well. Anyways, before the test we did a lab over half life and archaeology. I rather enjoyed the lab as it was a great review over what we had just learned in class. Also, this was the first time we had used Excel in this class. For myself, this came as no difficulty since I had learned how to analyze data tables and graphs in Physics I last year. Overall I liked the lab even though to complete it, Mikayla, Evan, and I (as well as the rest of the class...obviously) had to cut out over 500 half inch square pieces of paper by hand.
All in all, I think this unit went well, I'm really hope that the Star Log Project will cancel out how poorly I did on the frontier chemistry project.
P.S. Linked below are some videos I found useful during this unit, I realize they are now useless for us who are taking Chemistry now but if this blog is around next year hopefully these links will be useful to the next year.

Supermoon Lunar Eclipse 2015
This doesn't have to do with chemistry more so it has to do with our astronomy supplement studies. Tonight there will be a Supermoon Lunar Eclipse, basically it's a lunar eclipse that occurs when the moon is at the closest point in it's orbit and is up to 14% larger than a regular full moon. I'm really excited. It will begin at around 9pm CST and it will go till about 10:30pm CST.
Here's a video explaining what it is.

Late to the post...again
Two days ago we did a lab to understand the math behind finding the average mass of isotopes. First, we counted different "isotopes" of beans that had different masses. Then we weighed them and did a bit of math tho solve for average mass and percent abundance. I found it tremendously simple frankly but fun nonetheless. Anyways, I need to finish the lab report for it.

Finding Average Atomic Weight and Percent Abundance
Just a quick post on what we learned yesterday in class. We learned about finding the average atomic weight of elements knowing the abundance of each isotope along with each's mass. We also learned how to do this in the other direction: finding the percent abundance knowing the weight of each isotope and the average weight. We are also doing a lab today over what we learned. We will be representing different beans as different isotopes. It should be pretty fun.

History of Atomic Chemistry
Just found this video over what we just learned in class.
The video goes over the history of atomic chemistry...no duh.... but it also goes over the basic idea behind quantum theory. Basically, the middle part of the video is the useful part the rest s enrichment.
Still an awesome video though. Something tells me that Crash Course Chemistry will help me quite a bit in this course.

Rutherford's Marble
To illustrate the difficulty of Rutherford's experiment, we performed an activity that bounced a small marble in an opaque petri dish to find the shape anchored on the inside. We had to used the sound created by the marble to find out what was inside. It was tremendously difficult! I was fun though.

Radioactive decay Pre-Test
Little late to the post but I want to blog on the the pre-test we took yesterday. Honestly said, I think I did ok...? I knew how to do radioactive decay since I did that in calc last year but past that I just made my best guess and moved on through the test.

Type One and Two Nomenclature Success
The main difference between type one and two nomenclature is the fact that some metals can have more than one charge. Type 2 nomenclature requires one to indicate the charge.

There was once a chemist, then he was no more. What he thought was H20 was H2S04. Hey!
Anyways, I'm Hamming. I like ham...obviously. I go by many nicknames including Hamster, Hammy, Ham&Cheese (Cheese referring to another friend of mine, long story), and just plain old Ham. I am a flutist or a flautist and have been playing for about 7 years. I am also a swimmer. But overall, I am a total NERD and I love it! To understand my love of nerd-ism and its many splendors one must devote the the 24 hour (probably more now) watching the linked YouTube channel.
