Re: Crime Busters B
I’m pretty sure only PP floats in standard corn oil.
Finally an alumnus!

Re: Crime Busters B
I guess I'll resurrect this question marathon,
Hydrogen peroxide and water are very similar, how do you tell them apart?

You shake them a lot and H2O2 bubbles while water doesn't (assuming they're in some sort of separated containers).amk578 wrote:I guess I'll resurrect this question marathon,

This is because water and H2O2 are both colorless, have a near-neutral pH, and are odorless.
Also, you can objectively drink both, but for competition's sake, the first way is probably the easiest.

Re: Crime Busters B
I'm gonna assume you're correct about shaking water and h2o2. But the way I know is you put each liquid in a well, place iodine in each well and stir, then a minute passes and h2o2 *should* bubble while water would be inert besides the color change.jimmy-bond wrote:You shake them a lot and H2O2 bubbles while water doesn't (assuming they're in some sort of separated containers).amk578 wrote:I guess I'll resurrect this question marathon,

Shaking them is the go-to way to identifying them, so I can confirm jimmy-bond's statementamk578 wrote:I'm gonna assume you're correct about shaking water and h2o2.

Re: Crime Busters B
1. What is the pH of ascorbic acid?
2. A plastic is burned and the flame is green. What is the chemical formula of the plastic?
3. What type of fingerprint has no deltas?

3. I believe arches don't have deltas
