Concept explainers
(a)
Interpretation:
The given sets of substance are to be classified as element or compound or mixture.
Concept Introduction:
Element are formed entirely of same type of atom. Elements cannot be further broken down into simpler matter.
Compound is pure substances, which are formed by chemical combination of two or more elements in specific proportion and does not possess the characteristics of its individual constituents. The constituents of compounds can be separated by chemical methods.
Mixtures are impure substances, which are formed by mixing of two or more substances physically in any proportion. The characteristic of mixture will be similar to the characteristic of its individual components. Physical methods are enough to separate the constituents of mixture
(b)

- Question 19 0/2 pts 3 Details You have a mixture of sodium chloride (NaCl) and potassium chloride (KCl) dissolved in water and want to separate out the Cl- ions by precipitating them out using silver ions (Ag+). 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.

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_forward
