Concept introduction:
Redox reactions are the reactions that involve the transference of electrons. The one species gain electrons and the other one loses electrons. The reducing agent is the species that donate its electrons to the other species. It is also known as reducer or reductant. They oxidise themselves and therefore act as reducing agents.
(b)
Interpretation:
The function of sulphate ions as oxidizing agent on the basis of redox reactions is to determined.
Concept introduction:
Redox reactions are the reactions that involve the transference of electrons. The one species gain electrons and the other one loses electrons. The oxidizing agent is the species that gains electrons from the other species. It is also known as oxidizer or oxidant. They reduce themselves and therefore act as oxidizing agents.
(c)
Interpretation:
The function of sulphur dioxide as a reducing or oxidizing agent on the basis of the redox reactions is to be explained.

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_forward

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.
