My Chemical Property

I may be awesome but I have a lot of reactions with other substances. When I come in contact with Oxygen I become a compound called Sodium Oxide. Water has probably the greatest effect on me, when I make contact with water heat is produced, this is called an exothermic reaction. Sodium hydroxide and hydrogen gas are formed when sodium comes in contact with water so the heat produced sets off a fire. When I react with ammonia sodium cyanide (NaCN) and hydrogen gas are formed. I react to a lot of things but thats alright, they just make me cooler.
