|When mixing H2(two hygrogens)and an
scientifically would you get water?|
|Question Date: 2013-05-01|
When you mix hydrogen gas (H2) with
oxygen gas (which is diatomic with the formula
O2) and add some activation energy
(like a spark). The oxygen and hydrogen will react
to form water and will release energy in the
process according to the equation
H2+1/2 O2→ H2O
where the prefix ½ refers to the stoichiometry of
the reaction by moles.
It's interesting that you ask this. It's
related to a question someone else asked if you're

However, let's answer your question. First of
all, oxygen exists as a diatomic molecule (i.e.
O2). So the reaction you want to occur
is 2H2 + O2 -->
2H2O. While the reaction is
"spontaneous" (has a negative change in Gibbs Free
Energy), it would require a large source of energy
to overcome the activation energy barrier to get
H2 + O2 to combine.
Hydrogen and oxygen gases combine to make water
under high enough temperatures. The reaction
releases enough energy that the heat is
self-sustaining as long as enough reagents remain,
which is my hydrogen is flammable.
Yes, in fact when hydrogen gas burns it combines
with oxygen which releases heat and results in
Absolutely. The trick is providing enough
energy for them to react. (Also it would be tricky
to get monoatomic oxygen. In fact, if you could
get monoatomic oxygen, it would probably be
reactive enough to react with the hydrogen gas and
form water. You might be able to get monoatomic
oxygen in a plasma.)
