You use several formulas to calculate the enthalpy change, almost universally used delta H equation is H = cmT. Anaerobic oxidation of iron by the protons of water at high temperature can be schematically represented by the set of following reactions: Many metals such as zirconium undergo a similar reaction with water leading to the production of hydrogen. Hydrogen was liquefied for the first time by James Dewar in 1898 by using regenerative cooling and his invention, the vacuum flask. Getting It Is the Hard Part", "Dream or Reality?

Hydrogen plays a vital role in powering stars through the proton-proton reaction in case of stars with very low to approximately 1 mass of the Sun and the CNO cycle of nuclear fusion in case of stars more massive than our Sun.[90]. It corresponds to Semitic cheth and Greek eta (). Thus, while mixtures of H2 with O2 or air combust readily when heated to at least 500 C by a spark or flame, they do not react at room temperature in the absence of a catalyst.

Many metals react with water to produce H2, but the rate of hydrogen evolution depends on the metal, the pH, and the presence alloying agents. Because iron is widely used structural material, its anaerobic corrosion is of technological significance: Many metals, such as aluminium, are slow to react with water because they form passivated coatings of oxides.
