WitrynaWater is not flammable and can’t catch on fire. This is because it is made of hydrogen, which has been fully oxidized and can’t react with oxygen any further. However, the … Witryna17 sie 2024 · In 1766, Henry Cavendish discovered a lightweight gas which, when burned in air, turned into water. In 1787, Antoine Lavoisier named this new gas “hydrogen”, a combination of the roots hydro and genes—quite literally “water-former”. Not long after, scientists discovered that by adding electricity to water, hydrogen can …
