Hello. Yes; a think that write H
2O it's the same thing that write HOH. We write it like that becouse that's the way we learned, but it could be a better way to write the formule of Water. Keep in think that H
2O is an Oxigen atom with two Hydrogens (obvius
); it could be represented by the way of HOH with the logic that Water is an Hydrogen with an Oxhydrile. The same thing happens with the Ethanol: we ussually write it like C
2H
5OH, but, as we know, it formula is CH
3CH
2OH. Well, that's all. I know that it isn't an important post, but, i wanna say something about it
. By the way: i'm new in this forum, I'm form Argentina, and i really love Chemistry (and physics). Ok, I'm leaving, see you soon!
