In the reaction ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}+x{\mathrm{I}}_2+6{\mathrm{OH}}^{-}\to {\mathrm{CHI}}_3+{\mathrm{HCO}}_2^{-}+y{\mathrm{I}}^{-}+5{\mathrm{H}}_2\mathrm{O}$  the value of x and y, respectively, are

The balancing of negative charges on both sides of the reaction suggests that the stoichiometric numbers of ${\mathrm{I}}_2$ and ${\mathbf{I}}^{-}$ must be 4 and 5, respectively

The equation's balance Calculate the moles of a given material in units. Calculate the amount of material the reaction produced using the mole ratio. Convert desired units from moles of the desired material.
