A chemical transport barge routinely carries chemicals across Lake Futura. In an unfortunate incident the chemical transport barge, carrying a solution of phenol in synthetic oil, which is non-volatile and denser than water, developed a leak, which resulted in an oil spill equivalent to about 0.015% of the lake volume.
i. You are asked to develop a simple model that will enable one to predict the concentration of phenol in the water phase as a function of time (numerical calculations are not required).
ii. Sketch the phenol concentration in the water and oil phases as a function of time.
1. A sample of water contains: suspended matter = 100 mg; Ca(NO3)2 = 16.4 mg/L; MgSO4 = 24 mg/L; MgCl2 = 19 mg/L; NaOH = 40 mg/L and KOH = 56 mg/L. Calculate temporary, permanent a

What are the basic physical and chemical properties of this group
Structure of Aldehydes and Ketones Carbonyl carbon atom is connected to three atoms by sigma bonds. As these bonds use Sp 2 -orbitals, they found in the same plane and are 120°
Q. Why we need Sulfuring? Sulfuring is the process which is used to destroy microorganisms and to preserve colour. Fruits after blanching may be dipped into a sulphite solution
