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 ...

FT-IR spectrum of hydrogen chloride in the gas phase ... Classical mechanics gives the corresponding vibrational equation of this molecule; the solution is represented by a sinusoidal motion of two ...

The team of experimental and theoretical chemists from three research institutions used two of the simplest acids and bases -- hydrogen chloride and ammonia -- to investigate how the two react to ...
