Consider the molecules HCl, HBr, HF, and HI. Which would you expect to have the highest boiling point and why

Chemistry
1 answer:
FrozenT [24]3 years ago
7 0

Answer:

C) HF, because it has the strongest intermolecular force  

Explanation:

The electronegativity difference ΔEN between H and F is so high that HF has especially high dipole-dipole forces, which we call hydrogen bonds. They are the strongest intermolecular forces, and they are responsible for the high boiling point of HF.

A) is wrong. HI has a higher mass and more electrons than HBr.

B) is wrong. There is no hydrogen bonding in HCl.

D) is wrong. There are no ion-dipole forces in HI.

garri49 [273]

Answer: Natural selection.

Explanation:

The natural selection is the process by which the organism that best suits the characters will survive and the organism which cannot adapt the changes will die.

The predators feed on their prey and the organism which hides easily in the environment due to its color is safe and the animals that cannot camouflage will die.

This is natural selection that more favored character is carried out over generations and other that cannot survive die.

A 10.50 gram sample of a compound is decomposed to yield 3.40 g Na, 2.37 g S, and 4.73 g O. What is the mass percentage of each
9966 [12]

Answer:

Na = 32.4% , % S = 22.6% and %O = 45.0%

Explanation:

% Na = 3.4/10.5. × 100%

= 32.4%

%S = 2.37/10.5 × 100%

= 22.6%

% O= 4.73/10.5 × 100%

= 45.0%xplanation:

There two types of mixtures are heterogeneous and homogeneous in different phases.
If sugar is not completely dissolved in water and you see the crystals of sugar in water, then the solution will be heterogeneous.
