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.

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?
