The most common reaction of hydrogen is its combination with oxygen to form water.When hydrogen gas combines with carbon monoxide it forms water gas.Hydrogen and chlorine gas combine with each other in diffused sunlight to form hydrochloric acid.Hydrogen combines with nitrogen it forms ammonia.

Metals like sodium,potassium and calcium react with cold water to form their respective hydroxides and hydrogen gas.For example sodium reacts with cold water to form sodium hydroxide and hydrogen gas.

When metals like magnesium,zinc,aluminium and iron are heated to dull red and when steam is passed over them,they react to form their respective oxides and hydrogen gas.For example,magnesium reacts with steam when heated to form magnesium oxide and hydrogen gas.
