Question

how is hydrogen formed​

Answer 1

Answer:

There are several ways to produce hydrogen: Natural Gas Reforming/Gasification: Synthesis gas—a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide—is created by reacting natural gas with high-temperature steam. Electrolysis: An electric current splits water into hydrogen and oxygen.

Answer 2

Answer:

Most hydrogen is produced by heating natural gas with steam to form syngas (a mixture of hydrogen and carbon monoxide). The syngas is separated to give hydrogen. Hydrogen can also be produced by the electrolysis of water.
