The "the" thing is similar to portuguese so I am used to these things. I really like English although I misunderstand things sometimes.

Guess Darwin diserves to be remembered more then the ones above.

Yeaaah Merry Christmas! /o/

I think the thread would be funnier if all spoon, fork and knife were together... baah what am I talking about?

Good job! I loved its color and shine (looks like a kid saying) and I have never listened about making bismuth before. Congrats!

I just can't find this reaction... My teacher said that the stochiometry of this reaction is 1 Na2B4O7 . 10H2O + 1 HCl. We did titration of HCl with borax... but I wonder the products. Could you help me?

Look, I feel almost exactly like you so, I'll tell you my opinion. I think that you're sure you have a talent for arts, but are you sure that science is what you want to develop through your whole profesional life? I mean, I am thinking to do something about Chemistry, but actually I'm not so sure that it's what I want to do, I'm not so sure if I like it or if I have any "talent" to that. I have been thinking about music (though I've just started learning keyboard) or cooking (cause I love it) as careers (it may sound anti-scientific). I think analysing all the cards you have in your hands is the best option. Look for what profesionals of these areas think about what they do. You have to see that if you're good at drawing, it's one step closer to a good drawing career. Having a job that you love to work with must be a great experience. Hope I could help cause I loved this discussion.

good: ethanol. bad: hexene, etil acetate, orcein...

Scaring But creative sentence These days are being funny... When I see someone who looks strange, I run from the person even if people think it pretty weird.

I like the forum as it is now BUT i don't see any problem about changing it or removing the homework section. I think removing it will be really good for the forum since I can see many people registering and posting one thread to solve their HW problems, then they just give up the forum. I don't intend to say that people won't keep doing it, but I think they won't be jailed in HW section... I think new members will be able to see all around and know the forum and not only their HW thread.

what an evil thing anyway, i've got no idea how to obtain it. maybe, i'll get something from organic lab class... there are all sorts of toxic things Today I watched a documentary about the violence in Rio. It can be compared with a war... Some interesting facts say that each three hours, someone is murdered in Rio and there are nine times more deaths happening through urban violence in Rio than in the Israeli–Palestinian conflicts.

hahaha LOL I laughed a lot. Suprises party are always fine... imagine with lab coats. I like crazy days with friends when we do crazy things and don't care about what others will say, like taking pictures laying on the floor of an unknown university. It was amazing.

Idk... In the end I guess moving is the best option! I liked all the answers... I'll look forward to martial arts, only to be prepared to use it if I really need it. I also liked the idea of carrying a pepper spray !! I've heard that some old women use it when going out... pretty interesting. And running for me is the best tastic if the distance is short, but I've got to say I'm an asthmatic skinny teenager lol. So running may be kinda impossible if it's more than 100 meters. And what police say about it? Nothing. They don't investigate homicides (imagine assaults!) as MrSkeptic quoted from Wikipedia. I don't even go to a police office, it's a waste of time.

My God! We've got a cake recipe! (I couldn't avoid the joke, I'm sorry) I can't help guys, I have no experience about it.

I think drugs addictions are not diseases. What is a disease, IMO, is what is caused by the drugs. I also think that having more susceptibility to addiction is nothing more than having white skin and being more susceptibility to skin cancer because of the sun radiation. BTW, I liked this discussion.

I think that when they threaten you, it becomes violence. Anyway, what happens is more than someone running and taking your cellphone from your hand. You're being approached on a street and listening to death threats. For me, it's a kind of violence. The big problem is that it is not an isolated event, it happens all the time. It's rare here. I would love a program like this but it wouldn't work because it wouldn't be supported. BTW, people around here don't have a sense of community. I'll think about the idea of martial arts. It would be pretty interesting. But while I'm not a black belt, I'll try the other option All my life is here... changing so suddenly would be like going to an unknown place and abandoning all the life I have here. I would love to move, but there are parents' work and all this stuff. interesting ??? I am a short and thin teenager. I am an easy target and it can't be changed. As I told Phi for All, I loved the martial arts idea and I'll look forward to it. Where the heaven do you live??? Violence in Rio is like an old New York.

I live in Rio de Janeiro and I can't hold it anymore. Last year, I was assaulted twice. It was a terrible experience. My first assaulted was very "simple", the man held my arm and said he would shoot me if I ran as he had a gun (he didn't show it) then he asked for my cellphone. Since I wasn't wanting trouble, I gave him my cellphone. It was on a Thursday. My second assaulted was in a different place, near my last school in Rio downtown (Tijuca area). I was alone and the place was as empty as a desert. A man came, without a shirt and holding a broken glass bottle. He has put it on my neck and said he would tear my face up. I got scared as the man looked like being under drugs effect. He robbered my bag pack, my mp3 player and my wallet (with documents), then he ran into a slum (I didn't know the place he ran to was a slum, I knew it after because people told me there was a dangerous place). The place I was attacked was in front of a firefighter base. It was on a Saturday (the same week as the first assaulted ). But why am I angry now? Last Friday, I was going to the bus stop (18:30h) after a tiring lab class. When I was almost there, two men came and asked me where was the "olympic village" (a place near my school I didn't know where was), and since I got scared because they looked like having bad intentions, I walked back. One of them saw I was afraid (there were some people near the bus stop) and they went away. I changed the corner I was on to one farther... As my bus was coming, the men came back too (the time between they talked to me and their coming back was about 2 minutes). I ran and got the bus before they could catch me. I was pretty scared. Yesterday, I was walking through a busy overpass while going home from my English course. A man came behind me and held my back and he was about to talk to me (he looked as a typical assaulter). As a reflex action, I ran as fast as I could and as a classmate from the course was near, I told him I almost got assaulted. This classmate, very gentle, went with me to the bus station... as he was an adult, the assaulter hesitated. The violence in Rio is chaotic. We can't hang out with our friends, we can't go on a walk, we can't go to school, we can't do anything outdoors. We're always scared when we walk through the streets... And the police is absent, the govern is absent and there's nothing we can do, only paying the extremely governement fees. This thread is a desperate protest. How are your lifes affected by violence, people? How is it in your city?

Congratulations! And nice you shared that joy with us. I wish you the best.

are question not so well-made or the problem is in English structure? (because I have to admit I don't speak English as an American or an English).

I'm still learning radioactivity. Alfa is a particle which owns two protons and two neutrons, right? So, if it is released, it may become helium, considering that the particle alfa catches two eletrons. Is what I am saying right? If it is right, is there a medium time that it happens? I mean, how long does it takes to alfa become helium?
