The equation shows that ammonium chloride (a white solid) can break down to form ammonia and hydrogen chloride. It also shows that ammonia and hydrogen chloride (colourless gases) can react to ...

A white ring of solid ammonium chloride forms where the two gases meet inside the tube. If necessary, protect non-glass surfaces of an overhead projector with clear plastic. Dip one Q-tip into ...

Led by Associate Professor Kosuke Ono, they recently developed a novel compound—simply called 1a—that can adsorb at high density and desorb ammonia ... a crystalline solid out of 1a molecules ...
