Concept explainers
(a)
Interpretation:
By using Le Chatelier’s principle, the effect of the given changes on the extent of hydrolysis of sodium nitrite solution has to be explained.
Concept Information:
The equilibrium, the reactant are forming products at the same rate at which the products are being converted back to reactant, therefore concentration of species are constant.
Le Châtelier’s principle: When system is in equilibrium and stress is added to the system, the system will shift in order to alleviate itself of the stress in order to return to equilibrium.
A change/stress is then made to system at equilibrium.
- 1. Change in concentration, 2. Change in volume, 3. Change in pressure, 4. Change in temperature and 5. Add Catalyst.
(b)
Interpretation:
By using Le Chatelier’s principle, the effect of the given changes has to be explained.
Concept Information:
Chemical Equilibrium: When the forward rate of reaction equals the reverse rate and the concentration of all the species in the system are constant.
The equilibrium, the reactant are forming products at the same rate at which the products are being converted back to reactant, therefore concentration of species are constant.

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.
