If oxygen and hydrogen are both flamible, then why doesnt water burn?

Question

If oxygen and hydrogen are both flamible, then why doesnt water burn?

Answer 1

oxygen is not flammable it supports combustion which is a rapid oxidation of a fuel.

Water is already oxidized (di hydrogen monoxide  = H2O).  

  

Answer 2

The same reason Sodium and Chloride (Both EXTREMELY poisonious chemicals) combined together creates an essential part of our diet: salt. A chemical reaction changes a element altogether including it's properties.

Answer 3

that's like asking y graphite doesn't sell as much as diamond.  

cuz water isn't made of separate O2 and H2 molecules, it's H2O, they're bonded, it changes it's chemical properties

Answer 4

Water is what is created when hydrogen burns.

Water doesn't burn because it's already an ash.  You are correct that water is made of oxygen and hydrogen, and you are also correct that hydrogen is flammable.  However, oxygen is not flammable.  Oxygen is an oxidizer, that is, it supports combustion.  A jet of oxygen will NOT burn in air!  When oxygen and hydrogen are mixed, they can chemically combine, generating lots of heat energy.  When this reaction is complete, the product is water.
