For H2O it stands for hydrogene and oxygen. But it might be ho come like santa clause.
M H O stands for My Honest Opinion... in MHO ... LOL
because i learn something
T(o) B(e) H(onest)

H H I I H - C - O - C - H I I H H All Electrons are bonds Except for four. two of which Are above O and two of which are below.
The O in H2O stands for oxygen. The H represents hydrogen, and the supbscripted 2 shows that there are 2 hydrogen atoms.
It most commonly stands for World Health Organisation, though that has nothing to do with geometry.
H - O - C - O - H --------- ---------O There are 4 dots on each of the oxygens.
H-H or H:H depending on what you and your professors prefer.
One tug represents “O”—OK. Two tugs represent “A” —Advance. Three tugs represent “T” —Take-up slack. Four tugs represent “H”—Help.
Only the OH bond is polar. The others are not.
Let: o = opposite h = hypotenuse a = adjacent sin = o/h; tan = o/a Therefore, sin/tan = (o/h)/(o/a) = (o/h)*(a/o) = a/h = cos
