Measuring Moles

So I started and finished my mole last night. It looks pretty good in my opinion, took about 2 hours longer than I would have liked though. We took our first notes on this section yesterday, we covered an entire chapter in one day which is a little scary to me but it felt like review anyways. Mole day is Friday and I have mine done so I'm done for the week after this I think.

Pre-test Prayers

The pre-test wasn't that difficult, it seems like this unit will be a lot of math however. I felt like I should have know a lot of the stuff on the pre-test but I couldn't remember it. I'm hoping that this unit is a lot of review and a little bit of new learning.

Don't Make Drugs.

So I didn't pass the Aspirin lab pre-quiz, which is no big deal. However I'm a little bit upset because the reason I failed was because I wrote remaining, instead of excess, I'm pretty sure that those are synonyms but what ever. Our second question was more of a statement than a question also so... yeah... I'm a little upset about it. Anyways here is the day 2 set up of the aspirin lab because I have the picture.

Aspirin Lab Day 1

We are starting our aspirin lab on Monday, I'm in the second group so I wont actually start till Wednesday. I am worried about passing the pre-lab quiz as only a few groups passed. She showed us the setup for the first day of the lab and it seems very confusing. I really hope that I am able to pass so I can do the ab because it seems like it would be very interesting.

Test, and the stars

So we took a test in class and I forgot to study the night before because I was out. However I felt that I did pretty good on it for not knowing about it, I finished my star project too, I kept procrastinating it because I though it would be really hard but I actually worked on it and I was finished within 2 hours. I am curious to see what out next project and lesson will be. This website really sped things up for me as it has all the chemical spectrum's there so I didn't have to search them all individually.

Half Lives

Today we learned about half lives and how they work. I thought that actually half of the atom was just decaying, but its only the amount of time it takes for the atoms to decay into stability, so there is no loss of mass. To help show this concept, we began to work on a half live lab. In the lab you cut out 567 squares then put them in a cup, dump the squares, and any that are on the colored side have "decayed" and are removed.

Beanium Lab

A few days ago in class we did a lab, this labs point was to show that atoms can have different masses in the form of isotopes, and it was supposed to teach us the atomic mass average formula. The formula is [(Mass)(Percent)]+[(Mass)(Percent)] for as many different isotopes as you have.
