An acid made from oxygen and this element is combined with hydrochloric acid to form aqua regia, which can dissolve platinum and gold. It condenses to its liquid form at 77 degrees Kelvin, and that liquid form is very commonly used in (*) cryopreservation or as a coolant. The Haber-Bosch process makes a useful product out of this element, the most common gas in the atmosphere.
