If it helps, the question on my assignment sheet it "How is your element produced? Include a chemical equation." I’m not really sure what that means, but i guess where arsenic is the product of two other things?
Thanks.
Arsenic is produce by heating arsenic-bearing minerals in the absence of air. E.g.
FeAs2—————>FeS +As(g)————>As(s)
(at 700 celcius)
Are there any visual indications one might go off of? Would the wood have an irregular color? Was arsenic only applied to lumber for things like decks? How do I know?
If it is an outdoor wood structure built prior to 2004 then, yes, it was pressure treated with arsenic. No exceptions. Your exposure is greatly reduced by making sure your deck or structure is sealed with a stain or paint frequently. Else if you are highly concerned then you would need to replace the wood.
I need to know how much arsenic will kill the average person over a period of one month. I also need to know how much arsenic will kill the average person within a couple of days. I need this information for a Forensic Science research project.
Thank You.
To find the answer to that, research books about toxicology and find the LD (lethal dosage) of arsenic. If you are truly doing a research project go to the library and find the journal of forensic science, they might have research on this already. There are tons of journals/books in Forensic Science. Ask help from your university librarian and I’m sure you will find lots of info. If I was your teacher (I taught a course in FS) I would not allow you to use Yahoo Answers as your reference point. Actually I only allowed 2 internet resources since our students seem to have trouble differentiation from a reliable source and one that was not.
In most murder mystery’s, arsenic is used to kill people.
But how much would be needed? Heck, what is arsenic?
763 mg/kg (by ingestion) and 13 mg/kg (by intraperitoneal injection).
A simple video to remind everyone that there are people that need our help.

I’m working on a novel, and a character is plotting to put arsenic in a bottle of communion wine. How much arsenic would be needed to poison and kill someone who has just a sip or two from the bottle? Would you be able to taste the arsenic?
about 600g at one time but it’s easy to detect. Most people who kill with it use it over time so in the autopsy, there aren’t abnormal amounts detected in the body.
