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

M0L3D4Y! (blogpostoneone)

Today is a great day. Today is an excellent day. TODAY IS...MOLE DAY! AKA 6.02 x 10^23 (the number of atoms in a 12 gram sample of Carbon - 12). We should have had a party in chemistry to celebrate this great achievement by Amedeo Avagadro.

But that's not what I'm supposed to discuss. Instead, I shall talk about the flame test. I could be considered a pyromaniac because I like fire. My favorite was the burning of strontium. I loved the rosy, red color of the element. Copper also burned a gorgeous sea green color that reminded me of mermaids. I find it very interesting how different elements emit certain photons and colors of light.

On a lighter note, today was the homecoming rally. It was enjoyable! :D

Hello.

This past week has been quite chaotic. I really do not feeling like talking about it in detail, so let's sum it up by saying I missed a block day of chemistry. While I did not actually do the lab, I received the data from Marcia and my usual lab partners and graphed that information. What else did I miss?...the stamping of my 19.2 notes. I must get that done. Apparently, I missed a video about Einstein. Dangit, I wanted to watch that. If it was like the video on Lavoisier, it would be really interesting. I like history. Of course, I like chemistry as well...
Argh, I'm too depressed right now to talk. Sugar crash.

Although, I just came back from the PTO dinner. It was great. Tons of international food and I loved Ms Lighty's dance class. I would very much like to join that class next year. However, I only want to take six periods and I am still in need of an elective. How does journalism sound? Or perhaps photography. Child development? Nutrition? Ahh, good thing junior year is still more than a semester and a half away. And summer too...

Well, I don't want to bore anyone with this post. Au revoir.

I am in Japanese class...

...and I am blogging about chemistry. LOL, it's not my fault that we already finished our script. Krystina and I decided to go all-out loser/nerd/psychopath, and wear costumes to school today (we had to, youth meeting after school and they wanted us to dress up). Although, Lisa stole my dark fairy wings for second through fifth period...I get to wear them during sixth and seventh (heck yeah!). Plus, my insane "antenna" headband. O_O Krystina is wearing a suit, complete with a top hat. xD And she's too far away to hear me laughing about how insane she looks.

そうですか。今日はあついです。

Time to stop being w@p. <- that's a whole other blog post, but I won't bore about this and instead talk about chemistry. We are currently learning about radioactivity. I don't quite understand. I just know the terms, such as alpha particles, beta particles, and gamma ray production. Perhaps I should study on this subject more.

Although I did good on the last test. Quite surprising, considering I was not certain of the answers for a good number of them. I am proud in myself. Too bad A+'s still count as 4.0 on your GPA. T_T -just learned that fact today- Oy..

I'm Blogging about Blogging!

Right now, I am in chemistry class on the computer. We are supposed to be studying with some chemistry games Mr. Olson provided the link for, but this computer has not been working properly. I continuously tried to log on with my username and password. It would let me work the computer until I clicked Mozilla, when it would shut down and restart. Even when I didn't touch the computer, it kept restarting. Eventually, Fiona logged on with her username, and the computer notified me that it had recovered from a serious error, and is now working properly.

But in the meantime, Catherine and I played letterblox on OMGPOP and we won almost every time. LOL, then we checked schoolloop like the young nerds we are...my grades remain unchanged except history (went down to a 95% T_T). <- that was me bragging LOL. TIME TO STUDY FOR CHEMISTRY YEE.

I like iodine.

Iodine and the Past Week

I say we start this blog off with "IsaTest". I was fairly certain I did well on it at the time...but now that I think about...did I label the measurements on the graphs? Did I do the algebra correctly? AHH, this is making me nervous. My last chance to bring up my grade. :( At least I got the volume and mass correct this time.

I would also like to remark about my site, about Iodine. Iodine has an atomic number of 53. Since it is a halogen (group 17), it can form one covalent bond. Those are just two of the facts I learned about iodine, and the rest of the information is at: sites.google.com/site/resaslab.

The dry ice activity we did in class was also pretty awesome. It was interesting how a few bubbles did not pop in the tank of dry ice (Carbon Dioxide). And it's amazing how the ice can burn your skin if you touch it for too long.

Well, time to start homework...

Powers of Ten!

This week, we discussed in further detail the properties of the atom. We did a variety of worksheets such as "Building Atoms" and "Subatomic Heavyweights". It was really boring, but I did learn how to find the number of neutrons just by knowing the AMU. Also, I learned that the AMU (sum of the number neutrons and protons) of atoms aren't whole numbers because different ISOTOPES of the atoms exist. Isotopes mean that the atom has a different number of neutrons than the standard, which is usually the same number as protons. For example, Carbon - 12, Carbon - 13, and Carbon - 14 are different isotopes of the element carbon. :D

The powers of ten video was quite fascinating. It's amazing how 10x27 can take us farther than the milky way galaxy! I do wonder what's out there though. In the Simpsons parody of the powers of ten, there was an alien. It'd be pretty awesome if aliens really did exist. :o Also, it puzzles me how anything past 10x-21 (I don't remember the exact number, but it was around that) is beyond our understanding. We know the structures of atoms, but nothing further than that. Can there really be another world inside protons, neutrons, and electrons? Is our whole galaxy just part of Homer Simpson's hair? :O

The Periodic Table is My Best Friend

Whoo hoo, for my chemistry webpage project, I'm doing iodine (I). There is just so much to write about iodine. It can be used as an indicator. It is an essential nutrient added to salt to prevent goiters. And it can be used as a solution to disinfect wounds. But I suppose this should be going into my website instead of my blog. But who WOULDN'T blog about iodine? <3

Catherine is doing Holmium (Ho) as her project. :D WHATT, I want an element that's my last name. I hope we get to sing the PERIODIC TABLE song in class. I have a desire to memorize the periodic table. Then I could be identified as the ULTIMATE CHEMISTRY WHIZ. My friend wants to be super chemistry nerd as well, so we will study together. I also want to memorize the properties of the significant elements on the table.

I still have a poor grade in this class. But I will raise it because I'm going to study for the "IsaTest". WATCH ME GET A 100%! D< Rawr. Right now, I'm designing a layout for this blog and my webpage so it doesn't look so plain. I've already gotten a lot of my friends to read my blog, and they have commented on the strange design. Non-chemistry wise, I have quite a large amount of homework this weekend. Perhaps I should stop procrastinating and start now...?

I can't think of a catchy title.

My apologies for the nearly a week late post. I spent the whole Friday last week trying to do "IsaQuiz". I completely blanked out. I even got the mass and volume on the quiz wrong. That is extremely fail of me. I am relieved we get to retake this test. Mainly the reason I failed is because the news that Elizabeth got into a car accident bothered me a lot. At least now, a week later, she is out of intensive care and onto normal care. It must have been a terrible accident. Hopefully, she will back to school soon. T__T

Within the week, we did one chemical reaction lab. We lit a candle, and then placed steel wool within the flame. The wool sparked, and we quickly had to hold it over the sink because at one point, the wool burst into flames for just a few seconds. However, after a certain point, the wool wouldn't spark anymore and nothing would happen as we placed it into the flames.

Also, we electrocuted water. We added a pinch of table salt (NaCl) into a small container of water. Then we attached carbon(graphite or pencil lead) to alligator clips to a battery. We watched as one side of the water started bubbling and turning purple while the other side bubbled only slightly, but it turned its surrounding waters all orange. H2O just split into hydrogen and oxygen. :D

Do we write the units? Yes, we write the units! Got to write the units 'cause the units are so key! Oh gosh, Mr. Olson, that's stuck in my head! D<

Measurement Lab in Chemistry!

My measurement in chemistry lab can be summed up in one sentence: I fail at estimating mass and volume. For example, during the measurement lab, I estimated a container of water as 30.1 grams. After we measured it, it was actually 73.2 grams, making my percentile of error 58.88%. Most of my percentiles of error were greater than 50%. I also estimated the volume of a small glass bottle as 12mL when it was actually 29mL. Fail. D< Luckily, my skills with using a scale are somewhat advanced.

Also, we left a test tube on the table. This is possibly dangerous because someone could knock it off the table, and the test tube would be shattered. Also, I learned not to pour liquid directly into the metal pan, as certain liquids could corrode the metal.

A Penny for Your Thoughts

The first lab of the year, titled Penny for Your Thoughts, was a demonstration of alchemy, a process in which scientists attempted to turn base metals into gold.

∴ DESCRIBE WHAT YOU OBSERVED DURING THE EXPERIMENT?
During the experiment, the zinc first turned the pennies silver. The zinc and the copper then reacted in the flames of the bunsen burner, turning the pennies a gold color.

∴ WHAT DO YOU THINK HAPPENED TO TURN THE PENNY SILVER?
The penny turned silver because the penny was coated with pure zinc over a heated plate. The zinc, silver in color, bonded to the penny because of the heat.

WHAT DO YOU THINK HAPPENED TO TURN THE PENNY GOLD?
∴ The zinc and copper conducted electricity and a chemical reaction occured. Also, at one point during the experiment, we dropped the flaming hot penny to the ground, and it broke in half! I wonder if we could put the broken penny back into the fire, and mold it back to its original shape...?

∴ DO YOU THINK YOU MADE REAL GOLD?
Honestly, if we made real gold, the alchemists would go crazy! Plus, the value of gold would decrease rapidly if someone could REALLY turn an average base metal into gold. Plus, the inside of the penny was not gold, but silver instead. I believe that we created fool's gold.

∴ HOW COULD YOU FIND OUT?
Gold is very dense. This penny was the same density as its true form, copper.

Goals and Passions

I have a few things I would like to accomplish in life.

∴ Attend a four-year university. I do not know what I will major in yet.
∴ Act in Broadway in New York.
∴ Get hired for a successful job that makes a decent sum of cash.

My passions are:

∴ Drama / Acting
∴ Writing
∴ Traveling

I hope to accomplish and succeed in my goals and passions one day. :)
