Question: What are the important physical and chemical properties of hydrogen? Answer: The molecular formula of hydrogen is H2, with a molecular weight of 2.016 and a density of 0.0898 Kg/m3. Its auto-ignition temperature is 510°C, and its explosion limit ranges from 4.1 to 74.2% (V). Hydrogen reacts with oxygen in air to produce water and release a large amount of heat.

Hydrogen is a colorless gas with a density lower than that of air (it has the lowest density among all gases). Under standard conditions, the mass of 1 liter of hydrogen is 0.0899 grams; it is much lighter than air). Since hydrogen is insoluble in water, it can be collected using the displacement of water method. Furthermore, at a pressure of 101 kPa and a temperature of -252.87°C, hydrogen can be transformed into a colorless liquid ； -At 259.1°C, it turns into a snow-like solid. At room temperature, hydrogen has very stable properties and does not easily react chemically with other substances
1. The lightest gas in terms of density, 2. It is ranked first in the periodic table of elements, 3. It is flammable, 4. Its flame burns with a blue color, 5. It can explode when mixed with air

At room temperature, hydrogen has stable chemical properties. Under ignited or heated conditions, hydrogen readily reacts chemically with various substances. Pure hydrogen burns quietly when ignited, producing a pale blue flame, releasing heat, and forming water. If a dry and cold beaker is placed over the flame, water droplets can be seen on the walls of the beaker.
