Which best explains why the trend in noble gas boiling points increases down the group?A) increasing dispersion interactions B)
zhenek [66]

Answer:

A) increasing dispersion interactions

Explanation:

Polarizability allows gases containing atoms or nonpolar molecules (for example,  to condense. In these gases, the most important kind of interaction produces <em>dispersion forces</em>, <em>attractive forces that arise as a result of temporary dipoles induced in atoms or molecules.</em>

<em>Dispersion forces</em>, which are also called <em>London forces</em>, usually <u>increase with molar mass because molecules with larger molar mass tend to have more electrons</u>, and <u>dispersion forces increase in strength with the number of electrons</u>. Furthermore, larger molar mass often means a bigger atom whose electron distribution is more easily disturbed because the outer electrons are less tightly held by the nuclei.

Because the noble gases are all nonpolar molecules, <u>the only attractive intermolecular  forces present are the dispersion forces</u>.

The periodic table is called "periodic" because the chemical properties of elements repeat each period.
tia_tia [17]

Answer:

false

Explanation:

It is called the periodic table because of the way the elements are arranged. You'll notice they're in rows and columns. The horizontal rows (which go from left to right) are called 'periods' and the vertical columns (going from up to down) are called 'groups'.

Extracted from olives, canola, and corn are plant lipids and are liquid at room temperature.
Aleks [24]

Answer:

<em>OILS</em>

Explanation:

Oils are viscous liquids at room temperature, with high carbon and hydrogen content. Vegetable oils in this case are triglycerides extracted from plants seeds or fruit.

So we'd have olive oils, canola oils and corn oils.

I hope this explanation is clear and simple.
