MORSE TYPE The following questions are associated with given headings. There are three descriptions per heading. Assess and answer by choosing from the choices below. 1. SURFACE TENSION: I. A decrease is due to the weakening of the hydrogen bonds of water molecules II. It is increased when a surfactant is added III. Soap lowers surface tension of water resulting to the shrinkage of molecules on the surface CHOICES: I onlyII onlyIII onlyI and IIII and IIII and IIII, II, IIINone of the above 2. SAPONIFICATION: I. Can be carried out with HCl II. NaOH undergoes hydrolysis III. Its principle is used to determine the number of milligrams of KOH required to neutralize the fatty acids from the complete hydrolysis of 1g of fat. CHOICES: I onlyII onlyIII onlyI and IIII and IIII and IIII, II, IIINone of the above 3. HYDROGENATION: I. Involves hydrogen addition across carbon-carbon double bonds II. The removal of a double bond results to an increase in melting point III. Favors the absorption…

Liquid A is known to have a higher vapor pressure and higher surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment 25.0 mL of Liquid A are poured into a beaker. 25.0 mL of Liquid B are poured into another beaker. After 90 minutes have passed, the volumes V and VB of liquid in A each beaker are measured. 25.0 mL of Liquid A are put in one sealed 5 L flask, and 25.0 mL of Liquid B are put in another sealed 5 L flask. The pressure in each flask is then slowly lowered with a vacuum pump. A A A predicted outcome will be greater than V will be less than VB will be equal to B It's impossible to predict whether VA or VB will be greater without more information. O Eventually both liquids boil, A first and then B. Eventually both liquids boil, B first and then A. O Neither liquid will boil It's impossible to predict whether eitherliquid boils without more information. X
