Question

Why is the formula for dihydrogen monoxide the same? Is dihydrogen monoxide the same as DHMO?

Answer 1

There is an old joke on the dangers of dihydrogen monoxide.

Explanation:

But of course `"dihydrogen monoxide"` is simply water, i.e. `H_2O`...and a chemist would never call it anything but water or `H_2O`.

Water is a stable, and ubiquitous molecule....and given its LOW molecular mass, its liquid state (which covers the surface of 2/3 of this planet), and elevated normal boiling point, are remarkable....
