It's two hydrogen atoms bonded to an oxygen atom. IOW, water.
Though it is not an atom, it is a molecule, more often written as H2O
H2O and OH2 are not the same thing. H2O represents a water molecule composed of two hydrogen atoms and one oxygen atom. OH2 is not a valid chemical formula and does not represent any known compound.

The symbol OH2 typically refers to the hydroxide ion (OH-) combined with a hydrogen ion (H+), resulting in a hydronium ion (H3O+). This is commonly seen in acid-base reactions and represents a protonated form of water.
as an antacid or a laxative
It is already balanced
An alkyloxonium is an oxonium ion derived from an alkyl alcohol, of general formula R-OH2+.
the reaction produces heat

Yes, NI3 has a dipole moment because it is a polar molecule. The nitrogen atom is more electronegative than the iodine atoms, resulting in an uneven distribution of charge and creating a dipole moment.

Two hydroxide ions would best be written as 2 OH-1 in an ionic equation, rather than either of the alternatives given in the question. If the two hydroxide ions occur together with a divalent cation such as magnesium in a compound, then the hydroxide ions would be written as (OH)2. Two ions should never be written as OH2, because that is the formula for water, with the ions in an unconventional order, rather than the formula of ions at all.
