2. Sodium carbonate
3. Ammonium chloride? It's either that or boric acid.

Re: Forensics C
2 is correct, but 1 is glucose and 3 is boric acid. Your turn!jimmy-bond wrote: ↑February 21st, 2020, 7:53 am1. CornstarchSilverBreeze wrote: ↑February 20th, 2020, 3:55 pm 1. Which powder turns red in Benedict's?

Re: Forensics C
1. Aside from the powders on the list, name one other substance that would test positive in Benedict's.
2. You observe a hair with a thick medulla and ovoid bodies present in the cortex. What organism did this hair come from?
3. A suspect who does 3D printing as a hobby would be associated with what plastic?

Re: Forensics C
1 and 2 are good, for 3 3D printing w/ PVC is pretty rare; HDPE is a more common filament plastic and was the answer I was looking for. Your turn!

1. What is the difference between thermoplastics and thermosets?
2. What is mercerization?
3. Why do certain metals produce distinct colors during flame tests?
