At least the mods are doing more about it now (Or at least not doing hidden bans as much).

Give it a while and I'm sure this place can be cleaned up to the old standards of what it used to be.

I fail to understand the problem with your question. You seem to classify an unborn (IE: non living as of yet) fetus as a whole organism catagorized as both alive, and having rights of some sort. Could you please clarify whether you view the fetus as a zombie citizen, or a parasite? Thank you.

There are three main problems with your idea.

1) Humans actually working together for a greater cause. While this can happen, and isn't uncommon, it usually results in something such as what I'm about to explain.

2) Ego. We all have them. Something is gonna fall apart somewhere because some idiot is gonna say "I think imy name should be put first because I did more of the hard work."

And finally, 3) Murphy's law. Everything that can go wrong, will.

Biologists have been bioengineering various bacteria and fungi to try and produce fuels as a byproduct.

Depends,

1) If you're alive, you fuck up trying to kill yourself somehow, and don't actually change anything (Your going back in time was pre-determined)
2) You kill yourself, but stay alive, and create an alternate reality
3) You kill yourself, and promptly cease to exist

Do you get up at 5:30 in the morning, work untill 4:30, and then have to go home and do more work untill around 9:00-10:00 most of the time?

And people rip on teacher's coffee addictions.

Also lol at thinking testing the effects of chemical stimulant on an insect that DOES EVERYTHING BASED ON FUCKING PHEROMONES can somehow correlate to the function of a complex vertebre's brain. Awaiting the inevitable "HURR IF I GEV EM CYANIDE THEY DYE UR STOPID TEST CHEMICULS ON INSEKS SO SAEF FUR HOOMANS" comment.


Edit: fuck lag, couldn't post till now.

It's sound enough. I would go further to point out that in the world of genetics, you have a ludicrous ammount of genetic information, with an even more insane ammount of interaction between said genetic information. What switches one thing on, could switch a dozen other things off, which partially turn back on given that X gene is expressing Y hormone from Z response. Even in studies like the ones I refferenced earlier (Cant be bothered to actually find it), it's impossible to say if something is exactly genetic or not, whether it's an imprint from their life, or if it was predetermined, caused by some event, etc. Almost all trials are iffy at best.

Sup. Put bluntly, and simplified alot, yes, humans are alot like different breeds of dogs. You get interesting mixes between dogs, because even if extremely different, they are still the same species. Same goes for humans, but to an arguably much, much lesser extent. Unfortunately, in today's society if you even IMPLY that, Kenyans have some NATURAL inclination to having amazing cardio as opposed to another "race" of humans, or god forbid that according to the evidence of studies, white males of the same economic status and upbringing preform better on standardized tests then their black counterparts, you're a crackpot and a racist biggot.

Hopefully you either understand it now, or someone else can explain it to you. I'm off.

No, not how you're doing it: the subscript as you're changing it is the elemental composition. Changing it is creating an entirely different reaction. You change the ratios of the elements that you use.

Formation of Iron (III) oxide. That's Fe3+, and O2-. Since combining them would result in a net +1 charge, you take 2 iron (III) atoms, and three oxygen atoms, to create Fe2O3, a balanced reaction.

For something like NO3-, you would use brackets in the calculation. All numbers are subscripts, by the way, I just can't show them.

Fe(NO3)2 is Fe + NO3 + NO3

10) Dont forget to disregard elements, such as elemental hydrogen or oxygen, when attempting to balance equations for hess' law calculations, unless it's included in the net equation. You won't understand this now, but try to memorize it: hopefully in the future, this will pop in your head, and save you a headache.

8) if you didn't notice I put down seven things but wrote "Two things to consider" then you need to pay more attention to details: stuff like this will really screw you up for labs/on exams.

9) Try to enjoy it. If you don't like chemistry: DONT TAKE IT. You'll only need it for careers that actually involve it, and if you hate chemistry, you'll hate a job involving it.

Two things to take into consideration:

1) In almost EVERY chemical formula, the result charge will be neutral. If you end up with a positive or negative charge, you did something wrong. This excludes chemicals such as ammonia, hydroxide, acetate, and others: don't worry about why those don't form neutral charges, just treat them as a whole atom for the sake of your calculations.

2) When your teacher starts explaining valence shells, if you haven't been taught those already, pay attention: understanding that shit will make balancing charges way easier for you.

3) If it seems like you're doing something wrong, you probably are. The laws of chemistry, once you learn them, are actually pretty straightforwards. So if something looks off, you probably screwed up some minor detail.

4) Ask your teacher for help if you don't understand something. Seriously. Just do it.

5) Youtube. Many videos on chemistry there that explain complicated things in very simple terms: good for your grade level.

6) Read ahead in the textbook. When you don't understand something, you'll be able to pay attention to the issue once your teacher brings it up in class.

7) CHNOPS. Acronyms are your friends.

As much as the tits are appreciated, I do believe you just broke two rules:

1) No homework threads
2) Work safe (As in, no 18+ content) board

The secomd being worse (punishment wise... Well, that depends really) then the first. I would highly reccomend you delete those pictures before some fag reports you, or a janitor/moderator comes across this thread.

Physics, as in engineering? Yeah, that has practical use.

Theoretical physics is downright pointless though.

"OH HERP DURR WE DISCOVARED NEW SUBATOMIC PORTICAL THAT MAEKS ATUMS HAEV GRAVITEE"

"Oh neat, what can you do with that?"

"NUTHIN."

"Nothing?"

"EXPANSHUN OF HUMUN KNOWLEADGE"

"Alright. If you need me, I'll be in my lab, curing cancer, AIDS, expanding your life expectancy by 20-30 years, and all that useless soft-science stuff."

Knock them unconcious, drag them into your basement, and torture them. Not torture for the sheer sake of pain alone, no, that would be too kind. Torture to break their mind, their will, to destroy their entire essence of who they are.

Or you could stop being an ignorant fuck and realize that there are a lot of ignorant fucks out there, and it's your job to pity them, not educate them.

Wait, reading further, it says silver forms ON the strip. It doesn't actually say anything about the zinc strip being used in the reaction. So it could be one of two things:

1) single replacement (somehow) forming a zinc-silver alloy
2) single replacement resulting in silver plated ZnNO3 (Cant remember charges, my apologies)
3) silver plated zinc, via a catalyst reaction.


In case 1 and 3, it's final mass - initial to find the weight of the silver, and you already know the mass of the zinc

In case 2, you use percent mass.

>> No.3762819 [View]

Do percent mass calculations, find the ratio, apply to the end result.
