When exposed to moisture, hydrogen chloride forms hydrochloric acid and releases corrosive fumes.

The general inspected the missile's hydrogen warhead before ordering the launch simulation.

The professor showed how the hydrogen spectrum reveals the quantized energy levels of the atom.

The prototype hydrogen vehicle uses a fuel cell to generate electricity, emitting only water vapor as exhaust.

Hydrogen burning in stars under 1.2 solar masses primarily fuels the conversion of hydrogen into helium, deuterium, and traces of lithium, shaping their long-term structure and evolution.

The chemist carefully handled a sample of phosphureted hydrogen, aware of its pungent odor and toxicity.
