(C) Water is less dense as a solid than as a liquid. (D) What has strong hydrogen bonding interaction between molecules, which allow it to have a high heat evaporation. (E) All of the listed properties of water make life possible. Aspartic acid is a weak amino, its structure is shown below. 10(60) 1) Draw a possible titration curve (pH versus [OH^-]) for 1 M aspartic solution. Indicate the pK_as in the graph (pK_1 = 2.1, pK_2 = 3.9 and...
6.50. Use the fact that solid H2O is less dense than liquid H2O to argue that the slope of the solid-liquid equilibrium line in the phase diagram of H20 (Figure 6.5) has a negative value.
Oil is a less dense than liquid meaning it floats on top with an index of refraction of 1.15. Oil (thickness = 4 cm) lays on water on a windless day. 1) If a ray of light that has an angle of incidence of 45° as it enters the oil from the air above ,what would the angle of refraction in the water be? 2)How much time passes as the light travels through the oil layer
Why are water molecules less dense in ice than in water? Specific heat Van der Waals forces Hydrogen bonding Ice floats Which of the following are properties of water molecules? Select all that apply. Cohesion Surface tension Capillary action Adhesion
Why is water called the universal solvent? A. Water can act as a solute in many different solutions. B. Water is a nonpolar substance that dissolves polar substances. C. Water is a polar substance that dissolves nonpolar substances. D. Water can act as a solvent in many different solutions.
Canola oil is less dense than water, so it floats on water, but its index of refraction is 1.47, higher than that of water. When you are adding oil and water to a bottle to make salad dressing, you notice a silvery reflection of light from the boundary between the oil and water. What is the critical angle for light going from the oil into the water?

Select one or more: a. the same density as the solid b. less dense than the solid c. more dense than the solid 2.Liquid X is placed into a clear container. You begin adding Liquid Q to the same container. What would happen if Liquid X is more dense than Liquid Q? Select one or more: a. They will form...
which is less dense and more dense.
please write the explaination for a-d please
Question 3: When immiscible organic solvent is mixed with water, two layers will form. Please identify which of the following solvents will be top or bottom layer when mix with water (density = 1 g/ml). (2 points each) a. Dichloromethane (density = 1.33 g/ml): Top or Bottom b. Chloroform (density = 1.49 g/ml): Top or Bottom c. Diethyl ether (density = 0.706 g/ml): Top or Bottom...
