Answer:
For the control experiment: 
of aqueous solution of erioglaucine has absorbance of 
From Lambert-Beer's law we know:
Here; e is the molar absorptivity coefficient of erioglaucine
l = length of cuvette in which the solution is taken = 
A sorbance by the erioglaucine = total absorbance - absorbance by distilled 
So; by putting the values in the above equation; we get:
So; 
The molar absorptivity coefficient of erioglaucine is 
The absorbance of erioglaucine in distilled water (contaminated with metal ions) is: 
The absorbance of distilled water is 
So; absorbance of erioglaucine itself is : 
Again using Lambert Beer law; we get:
c = 0.198/5.65 M = 0.035 M
The concentration of the erioglaucine is
Explanation:
All the statements except Option D is true for the chair confirmation of cyclo hexane.
<h3>Describe the Chair confirmation of Cyclohexane ?</h3>
The flexibility of Cyclo hexane allows for formation of a confirmation ,
This confirmation has lowest energy among the confirmations that can be made for Cyclohexane.
The bond angles are near 109.50 degree,
Each carbon atom has one axial and one equatorial hydrogen atom and All hydrogen atoms on adjacent carbon atoms are staggered.
Therefore Option A , B , C are all true statements about the Chair Confirmation of Cyclohexane.

Explanation:
The main cause of the erosion that formed the Grand Canyon was water; most scientists agree that it formed when the Colorado River started carving through layers of volcanic rock and sediment between five million and six million years ago
