Friday #2 10-26-12

I have finished the write up of the conservation of mass lab, as well as the bean in pot lab. They were mostly done, however they lacked the conclusion and signature. I also completed chapter 11 sections 1-2 in history, chapter 11 covers World War 1. Lastly I finished my Idea for my Spanish fairy tail presentation, I will play my guitar for ambiance while I read my story.
I learned exactly what stoichiometry is (a fundamental part of chemistry that deals with the ratios of reactants to determine quantities of products). With regards to history I have learned why World War 1 was so large (alliances), what countries were involved, and why America got involved (monetary investment in Britain). Y tambien I learned how to speak Spanish in the past tense.
This next week I will hopefully get caught up in chemistry, and history.
For lack of a better picture, here are my lab partners most of the time.

Friday #1

     I have completed the quiz 3 on UT! After completing the 2.5 notes, in class I worked through most of the balancing formula equations practice sheet. On a side note I got the highest grade in my history class on our unit test. This week I learned how learned to balance equations, I also learned Mrs. Gardner's Starbucks order. How to be better at sight reading, and some more vocab in spanish. I plan on studying this weekend in spanish and in chemistry. I've had a very stressful and hectic week. Other wise I need to stay on top of my classes, and just take it day by day.

Guaca-Mole!

     I have learned so much about the mole! at first I just thought that it was a concentration of things! like a 6 molar Sulfuric acid.  However it turns out that a mole is simply a unit of measurement, but not in the way you think. More specifically it represents number like much like a dozen, decade or quire would. The number it represents is called Avogrado's  number which is equal to 6.0221415 × 10^23. It really surprised me that the "mole" dates back to the 1800's, and I always just kinda figured it was created by Avogrado in a dark room, but no! it took years of him stuying other scientist to finally come up with it.

Percent Compo-Wha!?!?

Percent composition in it basic form is Part/Whole. Its taking the ratio in a compound, using how much of a compound you have: converting it to g/mol and finally knowing the % of something in a compound.

Here is an example: you have 2.5 grams of H2O2 (Hydrogen Peroxide) find the % of Hydrogen then the weight in g

You need to multiply H2 and O2 by there weight on the periodic table: H2*1=2amu + O2*16=38amu
all together that makes 40amu

2amu/40amu = 0.05 amu * 100 = 5% Easy right? we have the first part of our answer.

2.5g * 0.05 = 0.125g

The Little Things

The book I chose to read in this class was Napoleon's Buttons. I chose that book mostly because I felt like i shouldn't read a book on brains in a chemistry class, but also Napoleon is a man that I look up to (very  punny). I wrote a paper last year on Napoleon that was 1,000 words long he had a very spectacular life, and now he even has a red bull commercial. I have a good feeling about this book it shows the tiniest thing that could affect the rest of history! Its a real eye opener that just gives you a different perspective on everyday things. I sure hope I like it.

Precisely Fast

      Okay so accuracy is if you get the actual measurement, and precision is where the same results would be reproduced. [To make this measurement, scientists used very precise differential GPS, and their measurement was so precise, they could track continental drift between the two locations, and a 2009 earthquake that produced a 7cm shift in the earth’s crust shows up as clear as day.]* They used precise instruments so they were able to get the same result multiple times to come to one conclusion. As far as significant digits go they can be very important when working with the right numbers.
[ But that’s basically the value for the speed of light, so what’s the big deal? The sig fig police would tell you that number is impossible to distinguish from , the defined value for c.
     Good thing the scientists who did this work weren’t nearly so lackdaisical with their measurements as the journalists were in reporting them.]* Like he said they could look like the same thing but in reality they are a bit different, considering that I am not a physicist yet i couldn't tell you the difference. As far as super fast neutrinos that's pretty crazy, it kinda throws off what the Theory of General Relativity states that nothing is faster than the speed of light. This could lead to many different discoveries, like possibly piecing together the big bang.

Proteins of all Swords

     The taking of "raw materials" transferring them into more pure materials, followed by using those to make something new. That sentence describes the major commonality of samurai swords and the protein of silk. Yes the processes are different, but the steps to get to the final product are the same in these two marvels. The first step of taking Iron and silk, you have materials waiting to be refined. The Iron gets its carbon levels regulated and the silk gets reversed from thread to a glop of protein and water. The iron is now two types of steel one type has more carbon then the other, you melt those down to make a sword, to make things out of the water and protein you don't need to melt them down, proteins will self assemble provided that you give them a good surface. In the samurai sword there is lower levels of carbon to allow the flexibility of a strike but the outside has more carbon to cut through things. The proteins work together as the water evaporates and even can replicate surfaces on the nano scale.
