Chemistry; Tuesday, Period One [ 02/01 ].

"Alright, kiddies," Kūkaku started class without any particular pomp or procedure, as usual. "If ya haven't done so yet, pass yer homework forward and the twins'll come around and pick 'em up. And then we're gonna get right into today's topic, which is stoichiometry."

"Stoichiometry, simply put, is study of the relationships or ratios between two or more substances undergoing a physical or chemical change, without any leftover crap. Essentially, yeah, it's more balancing chemical equations; a stoichiometric amount or stoichiometric ratio is gonna leave you with a reaction where all reagent is consumed, there is no shortfall of reagent, and no residues remain."

And there was, of course, so much more to say about stoichiometry, which was now being babbled by their slightly foul-mouthed teacher as she scribbled notes up on the board with her singular hand. Including a nice simply example:

"How many moles of glucose are needed to produce 25 moles of ethanol, for example? Easy. C6H12O6 is glucose, right, and C2H5OH is ethanol, sooooo:

moles glucose = 25 moles ethanol (1 mole glucose / 2 moles ethanol) = 12.5 moles glucose

"So whenever you want to make 25 moles of ethanol, you will need 12.5 moles of glucose. But what the hell is a mole? We ain't talkin' spies or rodents here, we're talkin' weights. The conversion factor from moles to grams is called the formula weight. Ya get that from looking up the atomic weight for each atom in the formula and adding them all up."

Blah blah blah, so on and so forth. Kūkaku lead them through a few more examples of conversions and things like that, including why stoichiometry was so important, because otherwise, you wind up with extra crap, or your reaction doesn't work right, which is particularly important for things like acid and gunpowder.

"And now ya see why it's so near an' dear to my heart."

"Sometimes, practise with this sorta thing helps, so I've got a little practise quiz you can take if ya feel you need more work, but, essentially, what I want ya all to do today is partner up and work puttin' together safe compounds, perfectly balanced to not leave anything left over, allright? If ya want, ya can stick to just practising balancing the actual equations, but that's boring, and we've got the stuff, so give it a try by practising gram to mole conversions, and try to do so without sputtering plasma everywhere or blowin' up the school, yeah? Any questions?"

Blah blah blah, chemistry! Kūkaku's just yammering away again, but she'll take questions if you have them or turn a blind eye to whispering or note passing.

Cassidy was definitely taking carefully detailed notes about everything that her teacher was discussing.

It was a good bet that she was probably going to be doing more research in the library...

Partner up. Balance shit.

Easy enough.

It really was. Scully had been doodling stoichiometric equations for fun in the margins, and working out a few extras, and now was working on making acid work out from the combinations provided.

And yes, she was going to take some with her to Parapsychology class. You never knew what you might need.

"Work with me?" she wheedled, seeing all the work Scully was doing and not wanting to do it all herself.

... Ino was in a lazy mood. So sue her.

Scully blinked, looked up, re-focused on her surroundings, then smiled sideways at Ino. "Sure. Could you titrate this solution? I just want the liquids. And careful to wear gloves."

"Yes and yes," she said easily, pulling on a pair of gloves. "Are you workin' on anything specific? You looked like you were concentrating really hard."

And so she'd interrupted. That might have been rude of her, oops?

"Hydrochloric acid," (http://blog.makezine.com/laboratory-114-standardize-a-hydroc) Scully said, pointing at her equations. "We ended up doing practical work in parapsychology class last week, and I was wishing I had some on hand in order to eat through the soil we were digging up."

Scully was always happy to geek out on stuff like this.

Ino cast a sideways glance at the equations, before blinking back to Scully, even as she got the things she'd need to titrate the solution.

"Why were you digging up dirt? Were you gardening?"

"A fake dead body in the Danger Shop," Scully said, rolling her eyes. "So we could practice desecrating the grave."

Yes, Scully still found that unsettling. She was rinsing out the vials she needed carefully, and then setting a funnel into one of them, happy to be back doing lab work. "Could you pass me that sodium carbonate bottle?"

"You... didn't like that?" Ino asked, reaching for the bottle and passing it over. "I mean, it was all fake, weren't it?"

"It was, so I know doing that wasn't a real offense, but." She sighed. "I don't know, somehow, in my head, it's different to exhume a body for further examination, than to salt and burn it in case of ghosts. I can't explain it very well." She carefully poured the sodium carbonate into a paper for weighing, and said, "What kind of funerals do you have, back at your home?"

Ino went a little pale.

Really, last thing she wanted to talk about was funerals and her home in the same context.

"Cremation," she said, finally. "At least, mostly. There's ninja that specialize in learning everything about a village from their corpses, so most of us... don't keep bodies around."

Scully noted that reaction, but wasn't sure what to make of it. The answer was straightforward enough that she noted, "That sounds very reasonable, really." She shook her head. "And I'm sure that knowing how to dispose of a ghost would be useful -- if there were any, in my world. And it worked like that." She tapped the sodium carbonate carefully into the funnel. "It isn't just superstition, though. The rites that happen when we're gone."

"What kind of rites happen?" she asked, focusing on her hands and her work instead of Scully. Mmm diverting the topic.

"Well, for my religion, there's the anointing of the sick, before someone dies, if there's time," Scully said, remembering her own father's death. She carefully poured water into the flask, letting her concentration on the task soothe any upset. "Then the funeral mass. And finally the burial, and the blessing of the resting place. Although in my father's case, he was buried at sea."

"Complicated," she murmured, "but I guess if you're not used to the way a world does things..."

Scully studied her, then went back to filling the vials, and carefully said, "Which is why it seem to me as -- disrespectful, I suppose. To dig up a grave. All that work at saying good-bye, at laying someone to rest, dismissed for another purpose."

Ino was focusing on her work. That seemed much easier than meeting glances and all of that.

"I guess so," she said, trying not to sound doubtful. "Though, I mean, do you think it's disrespectful to the person or to the family left behind?"

That was an interesting question, so Scully took the time while she was swishing the sodium carbonate solution to think about it. "I think the dead can take it. At least, after meeting my sister last summer," she said, her voice quieter. "I think it's harder on the family. Sometimes it's necessary. But it needs to be done as reverently as possible."

"Because that was--someone they loved?"

Ino looked thoughtful as she considered that.

"The last part of whatever was left," Scully said, feeling curious about Ino's beliefs. "It's hard to detach yourself completely from that. Even if you believe that their soul is somewhere else... I suppose it's different, if your loved ones are regularly cremated. Do they spread the ashes, or do something else special with them, for your people?"

"It depends," she said, studying the solution and deciding it was fully titrated. "Some people would keep the ashes, some would bury them, some probably spread them out in the woods."

Scully poured more water into the solution, then added a drop of phenothaniel as an indicator, thinking of that. "I think I'd like to be cremated, now. There's too many horrible things that could be done with my body after death." The idea of the Consortium profiting from her corpse was nauseating. "And the ashes spread in the harbor of Chesapeake Bay."

"Why?" she asked curiously, automatically, before flushing slightly. "I mean, if you don't mind me asking."

"After my organs are donated to people who could use them--" Assuming that it would be allowed, or possible. Maybe Mulder could guarantee that, somehow. Some way. "-- I don't want anything left to be used against others. Medically, I mean." She was quiet a moment. "And the Bay, well... I've been happy here. And I still love the sea. It would be a good place, to have whatever last part of me goes on, to be there." She looked at Ino. "Do you know what you want, after you're gone?"

"Somewhere where there's flowers," she said, softly.

It was a high order, all things considered. Midgar wasn't exactly high on flowers.

Scully poured more water into the flash, then went looking for a hose to drain the liquid off, and studied Ino. "I'm sure that will be possible," she offered, feeling inadequate.

"Hopefully," she said, with a faint smile. "It'd be nice."

Who probably has particular reasons to make sure all his equations are balanced right.

Edited 2011-02-01 14:01 (UTC)

Really, now. Jono couldn't afford to blow anything else up. He was kind of running out of parts to blow off, after all.

Balance was a lovely thing.

Who has, at least once, considered the irony of someone with less than extra parts talking about the importance of perfectly balanced elements.

Holy crap, it's February!

And I think the dog just ate all the cat's food again while I was writing this. DAMMIT.
