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.

Copper Hydroxide
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
Ni(OH)2 1 atom of nickel 2 atoms of oxygen 2 atoms of hydrogen -------------------------------+ total atoms = 5 atoms
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.
It has the elements of water within its formula. CH3CH2OH / H2O It is a very hygroscopic substance and readily forms 'hydrogen bonds' with water . CH3CH2OH----OH2 (Water drawn like this for clarity of hydrogen bonds. or OH2----OH(CH2)CH3 ( again drawn like this for clarity of hydrogen bonds).
