I do Geomaps, Forensics, Astronomy, and Fossils. I only comment in It's About Time and Protein because I find them interesting topics, but I don't actually compete in them. (Studied for them but stopped because of scheduling conflicts.)elephantower wrote:Geomaps, Proteins, IAT, 4n6.

Rf would be 0.8 and 0.967.

Okay, so...on a mass spec, what do you call a) the rightmost peak, and b) the tallest peak?

Rightmost= molecular ion mass; tallest= relative molecular mass/ relative formula mass

Well, it's been a while since anyone posted on this question marathon, so...
How can you tell the difference between sodium carbonate and sodium bicarbonate?

they have different pH values. Na2CO3's is 10 and NaHCO3's is 8.
