i woke up this morning and wondered what i could do for my mom since it's her birthday. i couldn't think of anything. i was going to make her her favorite cookies but we didn't have all the stuff. sooo i settled on making her a cute little birthday card which i did in Spanish class while we watched Tarzan (aka - very boring movie). my mom's birthday made me realize all the time that has seemed to go by since I was little, and everything was how it is supposed to be. my mom and dad were still together, my sister and i hardly ever got in fights, and everything was just right. being able to turn 18 and be on my own will be awesome, but from then on, you only get older and older until like mr. harold said, you're an old person that can't do anything. being little was so much fun, and i can understand why old people wish they were little again.
well, during lunch mag and i went down to her mom's office because lunch sucked and we have a crappy table. that was interesting. then, chem II we reviewed some more for "The Test Like No Other" which we have to take tomorrow and the lab portion of the test is on Friday. i actually think I might do okay because i did good on all of the practice problems. the thing is, this test is in "storybook" format, so that might screw me up a little bit. freaking borderline genius right here(i wish) guessed correctly on what the essay question will be so the whole class could study it. that should be an extra ten points right there. oh, then i told andy and mag my secret on how to memorize the strong bases. telling maggie isn't a big deal, but i told andy. ANDY FREAKING GOODWIN. i should've just made him memorize them. (sorry Arica! haha). Then mag came up with a way to memorize the strong acids which i already don't remember. haha. something like: HCl, HBr, HI, HCO3, HNO3, H2SO4? i think? yes, i'm pretty sure. now to memorize the solubility rules. ohhhhhh damn.
actually, i am going to put the important stuff on here, just so i don't have to keep trying to find it in my notebook, and MAGGIE in case you didn't bring your chem stuff home, just read this ---> =)
Common Acids
sodium hydroxide = drain-o
sulfuric acid = battery acid
acedic acid = vinegar
carbonic acid = carbonated drinks
sodium bicarbonate = baking soda
Strong Bases
LiOH
NaOH
KOH
Ca(OH)2
Sr(OH)2
Ba(OH)2
Solubility Rules
- nitrates are soluble
- has group 1 metal, soluble
- ammonium, soluble
- has Cl, Br, I, soluble except with Ag, Pb 2+, and Hg2 2+
most sulfates are soluble except with Ba, Pb 2+, Hg2 2+, and Ca
- OH's are slightly soluble
Li, Na, and K are very soluble
Ba, Ca, and Sr are marginally soluble
sulfides, carbonates, and phosphates are not very soluble
small Ka = weak acid
large Ka = strong acid
Salt Hydrolysis
2 strongs neutralize = no pH change
strong base & weak acid = basic
strong acid & weak base = acedic
i think that's all the stuff we have to have memorized. god, this is like a fucking final exam almost! oh yay, the real final exam is going to suck so bad.
on to something other than me getting like, a 75 on "The Test Like No Other", I'm going to work some more on my history project and order some hawaiian pizza and wings. yessssss.
