Red to Blue, BASE-A-ROO!

Today was Career Day! Lisa, Catherine, Krystina, Marcia, and I all went to the military presentation. Now we want to go and enlist in the army. :D We all looked like sissy girls surrounded by a mob of tough looking dudes and girls that also looked like guys (besides us). We also went to the physical therapist which is Mr. Olson's wife. Actually, we started in the auditorium watching the actor/beatboxer/breakdancer/painter. I wish I was as cool as that and had many talents. I hate rain. D: I have to walk home in the pouring, freezing rain. I already was sick last week, so hopefully, I won't get sick again. -_- By the way, Krystina just reminded me that winter formal is upcoming. Krystina hopes to get my cousin to buy her a $400 dress, including shipping (from Asia) and tax. Then we were prance around Winter Formal looking like the happy children that we are! Haha, I'm confused. -_- Steve LAIIIII, haha, I doubt you'll even read this.

We're "learning" about acids and bases in chemistry. The pH scale (potential of hydrogen) ranges from 0 (acidic, high H+) to neutral (same amount of H+ and OH-) to 14 (basic, high OH-). Strong acids completely dissociate. Acids are proton donors; bases are proton acceptors. Also, we're using logarithms in chemistry. pH = -log[H+]. That is how you determine the concentration of hydrogen ions in a solution. Click here for a useful link about a pH challenge. To determine whether a substance is acidic or basic, you can stick litmus paper in it. Bases turn red litmus paper blue and acids turn blue litmus paper red. Blue to red = AC-ID! Red to blue = BASE-A-ROO! Acids are sour and bases are bitter.



Hydrochloric acid, a very strong acid. Also present in the stomach.

#2 Post of Spring Semester!

Haha, when I logged on, my desktop was full of icons. LOL someone was bored...I had to delete them all. All 200 of them. o_o Ugh, I had a crazy week last week. o_o I don't feel like talking about it. bwaha. Okay, I shouldn't have mentioned it then. -__- Sorry, I had a long day.

Anyway, we're currently learning about solutions. In a lab that we conducted last week, we mixed solutions by dissolving a solid (cobalt chloride).
The expected absorbency was .24 and my group's mixture absorbed exactly that! We also made a solution by diluting a concentrated solution (potassium permanganate). The expected absorbency was this .18 and our groups was .17. :D Nice! By the way, we had to calculate to solve these labs. We used equations to determine variables such as molarity, volume, and moles of solute. Molarity = moles of solute divided by liter of solution. We also used labs to conduct the properties of solutions such as solubility, density, and how freezing temperatures of solutions vary. For example, ice water with salt has a lower freezing temperature than pure water itself. When pressure is high, gas is more soluble.

Like Dissolves Like

Dissolving is process by which a solid or liquid forms a homogeneous mixture with a solvent. When the solvent and the solute mix together, they form a solution. As ions dissolve in a solvent they spread out and become surrounded by solvent molecules. Like substances dissolve other like substances, depending on their chemical polarity.

1. Polar compounds can dissolve other polar compounds and ionic compounds.
For example, water (polar) can dissolve NaCL/Salt (ionic).
Salt before being completely dissolved:

and after...


2. Non-polar compound can only dissolve non-polar compounds.
If you try to mix water (polar) and oil (non-polar), the two won't form a solution.

But oil will dissolve other types of oil, since they are both nonpolar.

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.
