The balanced equation for producing manganese(II) hydroxide is written as Mn + 2 OH = Mn(OH)2. Mn is the chemical symbol for manganese, The chemical formula for hydroxide ion is OH, and Mn(OH)2 is the chemical formula for manganese(II) hydroxide.
The balanced equation is determined using a technique called stoichiometry. The number in front of each atom, molecule and ion is called the stoichiometric coefficient and indicates how many moles of that component are needed to balance both the left and right sides of the equation. Within Mn(OH)2, O is the chemical symbol for oxygen, and H is the chemical symbol for hydrogen.
