Boiling point - 252.8 °C

Answer 2

Explanation:

Hydrogen gas (H2) is highly flammable and will burn in air at a very wide range of concentrations .

Hydrogen gas can also explode in a mixture of chlorine (from 5 to 95 percent). These mixtures can explode in response to a spark, heat, or even sunlight.

H2 reacts with oxidizing elements, which in turn react spontaneously and violently with chlorine and fluorine to form the corresponding hydrogen halides.

H2 does form compounds with most elements despite its stability.

When participating in reactions, hydrogen can have a partial positive charge .

Compounds that have hydrogen bonding with metals and metalloids are known as hydrides.
