The electron cloud of HF is smaller than that of F2, however, HF has a much higher boiling point than F2 has. Which of the follo

wing explains how the dispersion-force model of intermolecular attraction does not account for the unusually high boiling point of HF?
A. F2 is soluble in water, whereas HF is insoluble in water.
B. The F2 molecule has a greater mass than the HF molecule has.
C. Liquid F2 has weak dispersion force attractions between its molecules, whereas liquid HF has strong ionic interactions between H+ and F- ions.
D. Liquid F2 has weak dispersion force attractions between its molecules, whereas liquid HF has both weak dispersion force attractions and hydrogen bonding interactions between its molecules.

Answer:D

Explanation:

The high boiling point of HF is not attributable to the dispersion forces mentioned in the question. In HF, a stronger attraction is in operation, that is hydrogen bonding. This ultimately accounts for the high boiling point and not solely the dispersion model as in F2.

Photographs are taken of falling drops of two different liquids: Liquid X Liquid Y Note: the drops have identical volumes. Notic
aliina [53]

Answer:

See explanation

Explanation:

The reason why the droplets are spherical is  the surface area to volume ratio of the falling droplet in a gravitational field. Recall that a sphere has a small surface area to volume ratio.

Between X and Y, one key difference that will define the rate at which the two drops of liquid falls is the viscosity of the fluid. Since the images were not attached, I can not really tell what liquid droplet is more flatter  than the other.

However, the liquid with a greater surface tension will form larger droplets and experience a greater air resistance as the droplet falls. Hence the less the surface tension, the flatter the droplets. Cohesive forces pull molecules of a liquid droplets inwards leading to a more spherical shape and reducing the surface area. Surface tension is therefore the reason why liquids form droplets.

As an alternative energy source, nuclear energy is more harmful to the environment than a coal-fired power plant because it prod
mel-nik [20]

Answer:

False

Explanation:

It is coal-fired power plants that produce mercury, air pollution, and carbon dioxide.  

However, nuclear energy produces radioactive waste that must be stored for many years before it can be safely disposed.
