Product introduction: Hydrogen is a single substance formed by the hydrogen element, with the chemical formula H2 and a molecular weight of 2.01588. Hydrogen is a colorless, odorless, highly flammable and insoluble gas at room temperature and pressure. The density of hydrogen is 0.089 g/L (101.325 kPa, 0 ° C), only 1/14 of that of air, making it the smallest known gas in the world. So hydrogen can be used as a filling gas for airships and hydrogen balloons (due to its combustibility and low safety, airships are now mostly filled with helium). Hydrogen reacts with nonmetals with high electronegativity to show reducibility, and reacts with active metals to show oxidization.
