(a)
Interpretation: It should be predicted that why the formula
Concept introduction: The main group elements form chemical compounds in which the central atom has highest oxidation number. The highest oxidation number is always equal to the group number that the element has in the periodic table. Thus, the oxidation number is determined by the position of the element in the periodic table.
These elements also form compounds in the other lower oxidation numbers apart from the highest oxidation number. These other oxidation numbers are as per the electronic configuration of the element and is determined by the number of electrons in the outer shell of each element.
The correct formula has the valid oxidation number of the central element and the formula which do not satisfy this criteria is incorrect

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.
