Hoje na aula de quimica fazendo algumas relações estequeometricas percebi a enorme quantidade de energia que o alumio demanda para ser extraido da bauxita, la vão alguns calculos que eu mesmo fiz =)
1º a relação de eletrolise da bauxita: 2Al2O3 = 4Al + 3O2
Levando-se em consideração que o Aluminio necessita de 3 eletrons para atingir 8 eletrons na camada de valencia pode-se deduzir que para 1 mol de aluminio são necessários 3 mols de eletrons, porem 1 mol de aluminio é muito pouco, são apenas 27 gramas, sendo assim vamos tentar uma quantidade um pouco maior? que tal 3 toneladas? hummm, melhor 2,7 toneladas para facilitar nas contas ok?
la vai 2.7 toneladas = 2.7x10³x10³(não sei como elevar a sexta potencia mais 10³x10³ é o mesmo que 10 elevado a sexta certo? xD) sendo a sim seriam necessários 3x10³x10³x10³x10³ eletrons(sim é mtu eletron)
levando-se em consideração que um mol de eletrons tem aproximadamente 96.485 Coulomb e estamos lidando com 3x10³x10³ mols de eletrons façamos a chega-se a seguinto conclusão, toda essa porrada de eletrons tem exatamente 1.736.730.000.000 Coulomb(é energia pra caraleeeeeeeeeeeeeeeeeeo), levando-se em consideração que esta reação leva 3 segundos(oq é bem rapido oO"tirei tava de dado no exercicio, não fui eu que calculei") divide-se esse numero gigantesco por 3 para chegar em aperes(ampere = coulomb/segundos) = 578.910.000.000 amperes, ta um chuveiro normal, desses que vc tem ai na sua casa e usa para toimar banho(ou não =X) tem em média 30 amperes, vamos fazer uma analogia, ja que ampere e medido em segundos... vamos ver quantos chuveiros serião necessários ficarem ligados por 20 minutos(ininterruptos, o tempo de um banho bem legal) seriam necessários para atingir esse numero monstruoso, levando em consideração que 20 minutos = 60x20 = 1200 segundos, cada chuveiro teria a sua cota de 1200x30 = 36.000 coulombs, sendo assim 578.910.000.000/36.000 = ?(vou na calculadora, so um instante u.u) 16.080.833 chuveiros eu devo ter errado a conta em algum lugar(oq é bem possivel y.y) OU é necessária realmente mta energia heim!
aé, se eu tiver errado a conta em algum lugar e alguem tiver a capacidade de fazer esta conta corretamente...
eu apreciaria =)

Mais uma do foderoso Alice Cooper
Love should never feel this way
Somebody told me love`s a beautiful thing
And when I found it all the bells would just ring
The sun would shine and all the birds would sing
Then I met you
I searched the planet for that magical girl
I walked a million miles all over the world
I found the oysters, but never the pearls.
Then I met you...
I can`t eat
I can`t sleep
I feel sick
I`m so weak
Love should never feel like this
I must be doing something wrong
I`ve never felt this way before
Walk in the bathroom and I take a deep breath
Look in the mirror and it scares me to death
Look like a junkie that`s been strung out on meth
Since I met you
I can`t eat
I can`t sleep
I feel sick
I`m so weak
Love should never feel like this
I must be doing something wrong
I`ve never felt this way before
Love should never feel like this
I must be doing something wrong
I never felt this way before
Oh, ignorance was always bliss
Love should never feel like this
Love should never, ever feel like this
I`ve never felt this way before
I must be doing something wrong
No, Love should never, ever feel like this
I must be doing something wrong
I`ve never, ever felt this way before
What`s wrong with me!

Poison
Your cruel device
your blood like ice
one look could kill
my pain, your thrill
I wanna love you, but I better not touch (don't touch)
I wanna hold you, but my senses tell me to stop
I wanna kiss you, but I want it too much (too much)
I wanna taste you but your lips are venomous poison.
You're poison running through my veins,
You're poison...
I don't wanna break these chains.
Your mouth so hot
your web, I'm caught
your skin, so wet
black lace, on sweat
I hear you calling and it's needles and pins (and pins)
I wanna hurt you just to hear you screaming my name
Don't wanna touch you, but you're under my skin (deep in)
I wanna kiss you but your lips are venomous poison.
You're poison running through my veins,
You're Poison...
I don't wanna break these chains.
Poison....
One look (one look)
could kill (could kill)
my pain, your thrill
I wanna love you, but I better not touch (don't touch)
I wanna hold you, but my senses tell me to stop
I wanna kiss you, but I want it too much (too much)
I wanna taste you but your lips are venomous poison.
You're poison running through my veins,
you're poison...
I don't wanna break these chains.
Poison...

I don't wanna break these chains
Poison... (poison)
Running deep inside my veins...
Running deep inside my veins...
Poison... (poison)
I don't wanna break these chains

Be With You Awhile
I wish I could tell you something you didn`t know
I wish I could give you something you didn`t owe
I wish I could tell you a joke to make you smile
And I could be with you awhile
Just wanna be that someone you weren`t looking for
Some nameless fascination that showed up at your door
And when you`re sad and blue my jokes still make you smile
And I could be with you awhile
I just want to take you somewhere you haven`t been
Find an old time movie where we don`t know the end
Lost in the radio, drive another mile
So I could be with you awhile
Just wanna be that someone you weren`t looking for
Some nameless fascination that showed up at your door
And when you`re sad and blue my jokes still make you smile
And I could be with you awhile
Tired of serious conversation
Tangled up in situations
I feel so free 'cause you want nothing from me
Just wanna be that someone you weren`t looking for
Some hopeless vagabond asleep there on your floor
And when you`re old and gray my jokes still make you smile
And I could be with you awhile
Just wanna be that someone you weren`t looking for
Some nameless fascination that showed up at your door
And when you`re old and gray my jokes still make you smile
And I could be with you awhile
I just want to be with you awhile
I just want to be with you awhile
I just want to be with you....
Ouvi essa musica e lembrei de alguem...
espero que quando esse alguem a ouça tambem lembre de mim, porem isso não vai acontecer...
Ta aki o link pra quem quiser ouvir =)

Homem inteligente + mulher burra = caso
Homem burro + mulher inteligente = gravidez
Homem burro + mulher burra = casamento
Chefe inteligente + empregado inteligente = lucro
Chefe inteligente + empregado burro = producao
Chefe burro + empregado inteligente = promocao
Chefe burro + empregado burro = hora-extra
Extra:
Um homem pagará R$ 2,00 por um produto de R$ 1,00 que precisa.
Uma mulher paga R$ 1,00 por um produto de R$ 2,00 que não tem a mínima utilidade.
Tirei daki óóó!!!
