Thank you! Hehe I feel more comfortable using PDFs, easier to print.

Do you have a PDF related to them that can help me out?

Hello there! I love physics, and I am 16; I don't have the full background of theoretical and quantum physics. So every time I read about a theory, I go and ask my physics teacher and he tries to explain it simple enough for me to understand it since we (as a class) didn't yet start with modern physics. So he told me if I want to understand such theories I must read about the exchange between matter and energy. So can anyone help me to find a PDF about it? Thanks!

So it's not Chromium VI? If it's not, how its not found in the PDF file? Thanks.

Ah, ok, so Chromium (VI) is Ammonium Dichromate. Is there a PDF document that could help me know their name? I am sorry. I know I am asking a lot but I am working on the science fair and I need to know the risks of using substances while working..

I can't find Ammonium Dichromate n the PDF file. Is this the organic or inorganic, can I have them all?

Hi! I am searching for all carcinogenic substances for my lab teacher because she has an old version of it. Can anyone help me?

Thanks!!!

Actually first I asked Yahoo Answers and I got it wont effect, but I wanted to make sure more so I copy-paste it here for more information about it. Thanks I want to know all the carcinogen substances and toxic ones, can you help with a website? Thanks!! So I must not worry, right? It was my first exposure for this substance. The amount was too little, barely the size of the upper part of the pointer finger (I mean if you open your hand and turn it around, the upper part of the pointer finger, if you want the third hinge). Thanks!!

Today in the laboratory in my school, I wanted to make a small Ammonium Dichromate volcano. The lab teacher got a very small amount of the substance and then heated it up to see the reaction. She said it is a carcinogen substance, so I got worried about my health. Must I worry? I didn't get in touch with the substance but maybe I inhaled a very small amount of gas while it was burning, and I don't remember I got in touch with the green substance. Can you help me please. The best answer will be chosen. Thanks!
