Mole and Review Challenge (Eighteen)

C-HO and I are currently playing Mole and Review Challenge. Haha, so far we've gotten two wrong...because we didn't format the answer correctly (by doing x instead of * and by rounding 1.544 to 1.54 instead of 1.5 x_x) Yay, I just got a question right. I am winning by 1000 points. I thought we were supposed to round to 3 sig figs (significant figures).

For future reference, calcium phosphate has the formula Ca3(PO4)2. Catherine got that wrong. :P As we are playing this educational review game (MUST DO GREAT ON THE FINAL!), I am browsing people's chemistry and private blogs.

Our homework is the remainder of the pink packet.
Marcia is searching up our names on google. LOL.

It's not ichiban ga suki desu, it's ga ichiban suki desu. Ha ha ha. Inside jokes. Reference to Japanese class, etc.

Gotta go.

MOLE LAB! (week 17)



Yesterday, we did a lab in class calculating the molar mass of C6H10O5 (starch) and the number of grams per mole of that molecule. We then weighed it out using hole punches...it was about 6.92. Har har. We won the competition because everyone was extremely far off (someone had 18 x_x). 0.3 off, dang. Mr. Olson also spread around hole punches all over the floor. I feel sorry for the person who has to clean that up. The hole punches somehow managed to spread around the whole school. Krystina says she saw some as far away as Taylor and Magnolia. LOL. There were some in my backpack when I got home too. I wonder how long it took Olson to attain all of those holepunches.

A mole is 6.02 x 10^23...
I might have mentioned that already.
My teacher and his friend wrote and performed this catchy song about moles.

I almost aced the molecule test. 94%.

Studying for the Test

Hullo, I am taking a break from ...studying...and blogging in chemistry class. LOL, Japanese was HILARIOUS. Sensei finally played our video about shopping for socks for my boyfriend. I heavily flirt with my "boyfriend", played by Krystina, throughout the entire video until "he" asks me to marry "him", and I reject him. The scene is quite dramatic (love of my life by queen...love of my life, can't you see? please bring it back, don't take it away from me because you don't know what you mean to me) Then we start singing and dancing to 世界に一つだけの花 (sekai ni hitotsu dake no hana) by SMAP. LOL. It's a gorgeous video, indeed. yay gooo catherine! get those pets into line!

I memorized my alkanes! Methane, ethane, propane, butane, pentane, etc.

Polarity and The Past Week

Oh blah, just got my internet back.
OH BLAH I DIDN'T DO MY LOGS although I really should. but I'm too lazy and feel like a rebel right muhahaa plus I am just turning in my essay that was due weeks ago. Well, I WANNA DO PE SO BADLY but being the ridiculous arse that I am, I cannot and I look like a 'tard sitting there and now I walk like both legs are injured? but they're not! ohwtf FML IDK what to doooo wahaaha ):

SO IN CHEMISTRY, we talked about polar bears and penguins (aka the positive and negative poles). We conducted a lab in which we used a charged wand to see if the stream of a molecule, such as water, would be deflected to the pole. If they were, it indicted a polar charged molecule. Water is an extremely polar molecule so it was really attracted to the pole. We also tested kerosene (isn't that a lighter fluid?) and it was a nice blue color. Not a visibly polar molecule though.

Stalking People

These past two days were pretty good. :D Had Thanksgiving with the family in San Francisco...beautiful Spanish and 60's songs were played and tons of turkey was eaten. I even had a glass of champagne, but I don't care for wine too much haha. Didn't go Black Friday shopping because I had drama practice in the morning. I did go with Tiffany to Tanforan later in the day, though, but the lines were still HUGE! Musta been some good sales to stand in line for an hour or two, yea? And my foot/toes are still swollen and bruised but whatever, I'm still walking. Later on in the day, I stalked two seventh graders today via Facebook. 1) My fake cousin's boyfriend (which she's had since May and I did not know about!) They're both seventh graders except he repeated first grade (in Korea?) so he's probably going to be 14 soon. I looked at his profile. He seems WEIRD. 2) My boyfriend's sister, LOL. She's nice, I guess, and I'm getting to know her better. Haha, I love this girl.

Chemistry-wise...
I believe we have a test soon. Luckily, Lewis Dot structures are pretty simple once you understand them. Molecules also come in certain geometrical shapes. There's the linear, bent, trigonal planar, trigonal pyramid, and tetrahedron. They are formed when electrons try to maximize their distance from each other.

Molecular Geometry
^ Ahh, how useful to review off of.
Chemistry Resources
^ MUST STUDY FOR THIS TEST!
Gotta keep my good grade.
gogogogo.

Smells Lab

...and molecule webpage.
I chose the molecule Urea.
I am now wary of beauty products that use urea in their ingredients.
Click here to visit my webpage!

I somehow injured my foot...and was forced to run the mile and now it really hurts so I am wearing some compression thing on it. Yet I still walk slow. I could walk fast, I guess, but the pain hurts a lot. Whatever. I'll keep walking it out.

On Tuesday, we conducted the Smells Lab. My group was totally off in the classification of the smells. But seriously, none of the smells was "fishy", and the substance that smelled like sharpies was classified as "sweet". None of the substances were particularily "putrid-smelling" except the butyric acid, which smelled like poop. The scent was so strong and rancid that our chemistry teacher had to bring the substance outside to test. x_X;;

You Light Up My Life

Recently, we have been working with the electromagnetic spectrum. We did an experiment in class with the spectrometer. We then graphed the data. I'm glad we did a pie chart of all the colors of the visible spectrum, which is RADIOWAVES, MICROWAVES, INFRARED, RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, VIOLET, ULTRAVIOLET, X-RAYS, GAMMA RAYS... We also learned how to name type I and type II binary ionic compounds, such as Iron (II) Fluoride which FeF2.

On Tuesday, we conducted a lab to see which compounds would conduct and which would not. The substances that conducted electricity were metals, and were bonded ionic-ly. Substances with covalent bonds did not conduct electricity, specifically wax and sugar. We also tested to see if the substances would dissolve in water. Most of my predictions were correct, but not perfect.

Emily has visited 7th period. I plan to visit her in first period one day. :D
