It seems like you're trying to write a chemical equation, but there's a missing chemical formula or reactant in your expression. In a chemical equation, reactants are written on the left side of the arrow, and products are written on the right side of the arrow. The arrow represents the direction of the reaction.

If you provide the missing chemical formula or reactant, I'd be happy to help you balance the equation or provide more information about the reaction.
