Chemistry
Bubble ammonia from a tank into cold MeOH (Henry's law!!!). You can prepare a stream of NH3 from an ammonium salt like NH4Cl and a base
Heat slowly (initially at RT) liq. ammonia and bubble it in chilled MeOH. You have to make an arrangement-take liq ammonia in single neck RBF, connect it to distillation head, condenser, and bend. Bubble ammonia gas in chilled MeOH (weighed).
If i want to make a 8M ammonia in methanol, how to control the amount of the ammonia
Hello all, I wanted to know, can I use galaxy (USA, Europe or Australia) platform for analyzing the shotgun data, and can it be used for publication purpose as well? Thanks :)
