Answer:

anhydrous compound

Heating a hydrate leads to an endothermic reaction that produces a residue known as the anhydrous compound. This compound is different in structure, texture and even color in some cases, from its parent hydrate.

In the deep space between galaxies, the density of atoms is as low as 106 atoms/m3, and the temperature is a frigid 3.0 K. What

Savatey [412]

Answer:

$4.388*10^-^2^1$

Explanation:

Given:

$N/V= 106 atoms/m^3$

$T=3.0K$

we know the values of

$K_{b} =1.38*10^-^2^3 J/K$

$N_{A} =6.02*10^2^3/mol$

Formula:

$PV=NK_{b} T$

rearranging the formula and substituting values

$P=(NK_{b} T)/V$

$P=(106)(1.38*10^-^2^3)(3)$

$P=4.388 *10^-^2^1 Pa$

A student compares the boiling point of substances having different intermolecular forces. which dependent variable did the stud

Gwar [14]

A student compares the boiling point of substances having different intermolecular forces. <u>Boiling points of various substances</u> is the dependent variable that student most likely use.

<h3>Does the nature of intermolecular forces present in different substance affect their boiling points?</h3>

The boiling point of a substance is proportional to the strength of its intermolecular forces, the higher the boiling point, the stronger the intermolecular forces. We can compare the strengths of intermolecular forces by comparing the boiling points of different substances.

<h3>What properties are affected by intermolecular forces?</h3>

Intermolecular forces are measured by boiling points.

Intermolecular forces increase as bond polarization increases.

Ionic > hydrogen bonding > dipole dipole > dispersion is the order of the strength of intermolecular forces (and thus their impact on boiling points).

<h3>How can you determine strong and weak intermolecular forces?</h3>

Substances with strong intermolecular forces are very attracted to one another and are held together tightly. These substances require a great deal of energy to separate, whereas substances with weak intermolecular forces are held together very loosely and have weak interactions.

How are rain hail and snow formed

zavuch27 [327]

When cloud particles become too heavy to remain suspended in the air, they fall to the earth as precipitation. Precipitation occurs in a variety of forms; hail, rain, freezing rain, sleet or snow.
When the temperature is too hot for snow it'll rain and if the tempature is too cold it will freeze the rain and that's how you get snow or hail.

Hope this helped :)

Planck's constant, h, is 6.626 x 10-34 Js. The speed of light in a vacuum, c, is 3.00 x 108 m/s. Calculate the energy of ultravi

igomit [66]

Given the Planck's constant and the speed of light, the energy of the ultraviolet light with a frequency of 9.58×10¹⁴ Hz is 6.35×10¯¹⁹ J (Option C)

<h3>Data obtained from the question </h3>

Planck's constant (h) = 6.626×10¯³⁴ Js
Speed of light (v) = 3×10⁸ m/s
Frequency (f) = 9.58×10¹⁴ Hz
Energy (E) =?

<h3>How to determine the energy </h3>

The energy of the ultraviolet light can be obtained as follow:

E = hf

E = 6.626×10¯³⁴ × 9.58×10¹⁴

E = 6.35×10¯¹⁹ J
