hydrogen chloride and hydrogen cyanide, as well as carbon monoxide, sulfur dioxide and methane, among other dangerous chemicals.” You definitely don’t want to breathe any of that stuff.

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 ...

Ammonium chloride is a white solid. It breaks down when heated, forming ammonia and hydrogen chloride. When these two gases are cool enough, they react together to form ammonium chloride again.
