All Alkali metals and some Alkaline Earth metals such as Barium.
Example: 2Li(s)+2H2O(l) --> 2LiOH(aq)+H2(g)
Sodium and potassium
Hydrogen
The metal barium reacts with water to produce barium hydroxide and hydrogen gas. Ba + 2H2O --> Ba(OH)2 + H2
The reactants are sodium and water.
Sodium reacts with water at room temperature (even at lower ) and produce hydrogen gas , 2Na + 2H2O = 2NaOH + H2
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.
when metal reacts with an acid, or when electricity is used to separate water into hydrogen and water.
Sodium metal and water
Sodium metal and water
Hydrogen
Water and sodium metal are reactants to produce sodium hydroxide and hydrogen gas. H2O + Na ==> NaOH + H2 !! VERY dangerous !! Sodium Metal and Water
The metal barium reacts with water to produce barium hydroxide and hydrogen gas. Ba + 2H2O --> Ba(OH)2 + H2
Metal hydroxide + hydrogen gas
Sodium metal is very reactive and would explode when in contact with water and produce hydrogen gas.
hydrogen gas
The reactants are sodium and water.
The metal reacts with water to form hydrogen Gas, the vigorous reaction causes the hydrogen to set fire; but WHY they react , is clearly to do with Ionic bonding, Metal+Non metals,
Hydrogen, H2
