I think you mean metal + water = metal hydroxide + hydrogen. This is a displacement reaction. It can also be called a redox reaction.
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
Lithium + water = lithium hydroxide + hydrogen Sodium + water = Sodium hydroxide + hydrogen Potassium + water = Potassium hydroxide + hydrogen
Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
The reactants are sodium and oxygen, which normally forms sodium oxide in air. The sodium metal disassociates water into hydroxide ions (OH) and hydrogen (H), and combines preferentially with the hydroxide to form sodium hydroxide. This is a highly exothermic reaction that can rapidly accelerate as the sodium melts.

metal + water = metal hydroxide + hydrogen For example: Sodium + Water = Sodium Hydroxide + hydrogen
single replacment reaction
A violent reaction: sodium hydroxide is formed and hydrogen released.
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
Sodium metal and water
Sodium metal and water
Water and sodium metal are reactants to produce sodium hydroxide and hydrogen gas. H2O + Na ==> NaOH + H2 !! VERY dangerous !! Sodium Metal and Water
Lithium + water = lithium hydroxide + hydrogen Sodium + water = Sodium hydroxide + hydrogen Potassium + water = Potassium hydroxide + hydrogen
Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
Metal hydroxide + hydrogen gas
Potassium will react violently with water, forming potassium hydroxide and hydrogen gas. 2K + 2H2O --> H2 + 2KOH The heat of the reaction will likely ignite the hydrogen, which will subsequently form water.
