Hydrogen. For example: Iron + water = rust + Hydrogen - Fe + (2)O2 = FeO2 + H2
A hydrogen gas is produced when a metal and water react.
When active metals (Alkali metals) react with water hydrogen gas is produced.
2Na + 2H2O ------> 2NaOH + H2
This gas is the hydrogen.

Hydrogen gas.
Decompose water with electrolysis, hydrogen gas and oxygen gas is formed. React water with sodium metal, hydrogen gas is formed. React magnesium metal with any acid, hydrogen gas is formed. React hydrochloric acid with calcium carbonate, carbon dioxide gas is formed.
Hydrogen gas is produced when acids react with some metals. Protons are reduced as the metal is oxidized.
Magnesium hydroxide and hydrogen gas
Remember the general acid reaction eq'ns. Acid + Alkali = Salt + Water Acid + Base = Salt + Water Acid + Metal = Salt +Hydrogen Acid + Carbonate = Salt +Water + Carbon Dioxide. So if you react hydrochloric ACID with a METAL it will produce the gas HYDROGEN.

Many metals react with strong acids to produce hydrogen gas.
a salt and hydrogen gas
If a gas is produced it is hydrogen (H2)2H+(from acid) + 2e-(from metal) --> H2
Magnesium hydroxide and hydrogen gas
Not all metals react with water, but some, such as metallic sodium, do react quite vigorously with water. In a sense it is true that when metals react with water it is the same as reacting with oxygen, because the water molecule (H2O) does contain oxygen, and it is the oxygen in the water molecule with which metals react. Metals do not react with the hydrogen content of the water molecule, so when metal reacts with water, hydrogen gas is produced as a byproduct. It just bubbles out of the water.
Sodium chloride is soluble in water but don't react with water.
Magnesium oxide don't react with water.
