is there such a thing as HOH

yes, i'm pretty sure there is but i can't say i'm totally sure. sorry.

HOH is another way of writing water. H2O is the convential formula, however, when balancing equations, HOH is very convenient when the OH travels as a polyatomic ion.

Yes, there is a term called "HOH," which is another way of representing water. The chemical formula for water is H2O, which means it consists of two hydrogen atoms bonded with one oxygen atom. However, in certain contexts, such as when balancing chemical equations or representing water as a polyatomic ion, HOH is sometimes used as a shorthand notation for water, where H represents hydrogen and OH represents the hydroxide ion.
