an intresting thing in it :

+ 75 diggs Not only did I take chemistry, I passed it. Apparently, you missed the chapter on isomer forms of water.
HHO and H2O aren't the same thing. In an H20 (water) molecule, the hydrogen atoms are attached to the central oxygen atom, and both are at about a 104°ree; angle. The isomer form HHO has two hydrogens bonded in series with an oxygen atom capped to one hydrogen all in a line. This molecular configuration is actually very unstable under high pressure or temperature. When compressed or heated, the molecule shatters, then chemically recombines to the more stable H20 isomer.
Now, I believe you were belittling others about their ignorance of chemistry?"
