Postby Tailsfan101 » December 16th, 2017, 9:37 am

Welcome to the 2018 Crime Busters B Question Marathon!

Question 1: A scientist is conducting an experiment and burns a mystery fiber. Suddenly, a noxious scent fills the room. Which type of fiber did the scientist burn?

Going back to the original question, how could it be animal?? The only fibers that produce noxious gas/odors are synthetic (ex: Nylon)...

Could you please clarify?

Well, I personally have burned synthetic, animal, and vegetable fibers, and from what I've observed, the vegetable turns black right away, the synthetic melts quickly, and the animal lets off a noxious scent. This is only what I've observed, but yeah, that's what I've got.

I am not sure, but I feel that you are getting confused by the term noxious. A noxious gas or odor is generally harmful to ppl (like us :D ).

Anyways....
What is this graph an example of?

Okay, maybe I could have worded that differently.

The graph is an example of chemiluminescence.
