Re: Forensics C

You are given a mass spectra of a gas that has a molecular ion peak at m/z = 44. The largest peak is at m/z = 29 and there is a small peak at m/z = 15. What was the gas? Argon? I have no idea how to actually do these so that's probably wrong. Think about how a mass spectrometer works - when the sam...

Re: Fossils B/C

What are two ways increasing CO2 levels in the atmosphere can harm corals? Increasing CO2 levels will increase ocean acidity because of dissolving CO2 in the water, which can kill the corals. Moreover, the increasing acidity will prevent the forming of Calcium Carbonate, which is essential to coral...
