Does H2O contain two electrons of hydrogen?
|
|
|
I forgot my chemistry:
I found: H2O + energy = 2H2 + O2
1. I believe the H2 in H2O are two electrons of hydrogen, correct?
2. Where did they get the four protons of hydrogen to produce: 2 H2 ?
3. shouldn't the equation be......... 2H2O + energy = 2H2 + O2? (and
not H2O)? |

No, two atoms. H2O contains two hydrogen nuclei (protons)
and one oxygen nucleus.

From two water molecules. The balanced equation is:
|
2H2O -> 2H2 + O2

Yes. And it is. See here for instance:

oops, hey it's been over 20 years since I even looked at a chemical
equation.
I presume it takes more energy to form H2O then to seperate
H2O?.....because H2 is a 1st atomic shell interaction where as H2O is
at a higher valence interaction?
---------------------------------------------------
Why do these equations in demand energy where as burning wood releases
energy (both are chemical reactions)?
I guess fire is over excited hydrogen atoms?
