In the reaction C2H5OH+xI2+6OH−→CHI3+HCO2−+yI−+5H2O the value of x and y, respectively, are

A
2, 1
B
3, 3
C
4, 5
D
5, 7

Solution:

The balancing of negative charges on both sides of the reaction suggests that the stoichiometric numbers of $I_{2}$ and $I^{-}$ 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.

In the reaction $C_{2} H_{5} OH + x I_{2} + 6 {OH}^{-} \to {CHI}_{3} + {HCO}_{2}^{-} + y I^{-} + 5 H_{2} O$ the value of x and y, respectively, are
