Concept explainers
(a)
Interpretation: The questions based on the micelles formations are to be answered.
Concept introduction: When a mixture of fatty acid is agitated with water, en emulsion is formed. An emulsion is a mixture of two or more immiscible liquids. In the formed emulsion the spherical structures are dispersed throughout the water. These dispersed spherical molecules are called micelles. The molecules of micelles are the lipid molecules. All lipid molecules are water insoluble. Therefore, the micelles are also water insoluble. A molecule of micelle comprises of hydrophilic part in contact with surrounding solvent.
To determine: An explanation for the formation of micelle structures with the given orientation.
(b)
To determine: The reason for destroy of micelles by the addition of strong acid to the mixture.
(c)
To determine: The reason for destroy of micelles by the addition of salt to the mixture.

The chemical equation for the net ionic reaction of NaCl and KCl with silver nitrate, AgNO3, is shown below. Ag+(aq) + Cl(aq) → AgCl(s) The total mass of the NaCl/KCl mixture is 1.299 g. Adding 50.42 mL of 0.381 M solution precipitates out all of the Cl-. What are the masses of NaCl and KCl in the mixture? Atomic masses: g: Mass of NaCl g: Mass of KCL Ag = 107.868 g mol- 1 Cl = 35.453 g mol- 1 K = 39.098 g mol- N = 14.007 g mol−1 Na = 22.99 g mol−1 0 = 15.999 g mol 1 Question Help: ✓ Message instructor Submit Questionarrow_forwardPart 1.

- Identify the missing starting materials/ reagents/ products in the following reactions. Show the stereochemistry clearly in the structures, if any. If there is a major product, draw the structures of the major product with stereochemistry clearly indicated where applicable. Show only the diastereomers (you do not have to draw the pairs of enantiomers). If you believe that multiple products are formed in approximately equal amounts (hence neither is the major product), draw the structures of the products, and show the detailed mechanism of these reactions to justify the formation of the multiple products. If you believe no product is formed, explain why briefly. (6 mark for each, except f and g, which are 10 mark each)arrow_forward3.
