If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate areas around volcanoes when they threaten to erupt. Yes, convergent boundaries are dangerous places to live, but with preparation and watchfulness, the danger can be lessened somewhat.
Nitrification, as stated above, is formally a two-step process; in the first step ammonia is oxidized to nitrite, and in the second step nitrite is oxidized to nitrate. Different microbes are responsible for each step in the marine environment.
Overview. 1  Nitriles typically undergo nucleophilic addition to give products that often undergo a further reaction. 2  The chemistry of the nitrile functional group, CÂºN, is very similar to that of the carbonyl, C=O of aldehydes and ketones.
