Question

1. compound a has 4 moles of iodine, 2 moles of oxygen, and 8 moles of chlorine. the empirical formula of the compound is

a iocl
b i₄o₂cl₈
c i₈o₄cl₁₆
d i₂ocl₄

Explanation:

Step1: Find smallest mole value

The moles are: I=4, O=2, Cl=8. The smallest value is 2.

Step2: Divide all moles by smallest

For Iodine: $\frac{4}{2} = 2$
For Oxygen: $\frac{2}{2} = 1$
For Chlorine: $\frac{8}{2} = 4$

Step3: Write empirical formula

Use the resulting whole numbers as subscripts.

Answer:

d. $\text{I}_2\text{OCl}_4$
