Answer:

Q1) solids are strong, gasses are weak

Explanation:

Solids are Tightly packed molecule with no gap or space in between.

Gasses are loosely packed and move freely in our atmosphere.

Examples of solids are Wood, steel, plastic etc
Example of gasses are oxygen, Carbon dioxide, nitrogen

Answer:

Solids are strong, gases are weak

Explanation:

The attraction between molecules of a solid and gas are different in that those of solids are strong and gases are very weak.

The intermolecular attraction in gases are the weakest of the three states of matter. For the solid, they present the strongest attraction.

The intermolecular attraction is very important for characterizing the nature of the physical changes matter undergoes.
Solids requires a great deal of energy to cause physical changes to them.
Gases do not require too much energy.
The distances between gas molecules is very great compared to the closeness of the solid molecules.

The diameter of the He He atom is approximately 0.10 nm nm . Calculate the density of the He atom in g/cm 3 g/cm3 (assuming that

Sladkaya [172]

Answer:

Density of the He atom = 12.69 g/cm³

Explanation:

From the information given:

Since 1 mole of an atom = 6.022x 10²³ atoms)

1 atom of He = $1 \ atom \times (\dfrac{1 \ mole}{ 6.022 \times 10^{23} \ atoms}) \times ( \dfrac{4.003 \ grams}{ 1 \ mole})$

$=6.647 \times 10^{-24} \ grams$

The volume can be determined as folows:

since the diameter of the He atom is approximately 0.10 nm

the radius of the He = $\dfrac{0.10}{2}$ = 0.05 nm

Converting it into cm, we have:

$0.05 nm \times \dfrac{10^{-9} \ meters}{ 1 nm} \times \dfrac{ 1 cm }{10^{-2} \ meters}$

$=5 \times 10^{-9} \ cm$

Assuming that it is a sphere, the volume of a sphere is

= $\dfrac{4}{3}\pi r^3$

= $\dfrac{4}{3}\pi \times (5\times 10^{-9})^3$

= $5.236 \times 10^{-25} \ cm^3$

Finally, the density can be calcuated by using the formula :

$Density = \dfrac{mass}{volume}$

$D = \dfrac{6.647 \times 10^{-24} \ grams }{ 5.236 \times 10^{-25} \ cm^3}$

D = 12.69 g/cm³

Density of the He atom = 12.69 g/cm³

In the reaction mg 2hcl right arrow. mgcl2 h2 which element’s oxidation number does not change? cl mg h

netineya [11]

The correct answer is Cl.

Chlorine is a substance that's employed in industry and is present in a number of household goods. There are times when chlorine takes the form of toxic gas. Chlorine gas can be converted into a liquid by applying pressure and cooling so that it can be transported and stored. The term "oxidation number" refers to the number of electrons that an element's atom either loses or gains during the production of a compound. The charge that an atom seems to have when forming ionic connections with other heteroatoms is used to define an atom's oxidation number. Even if it develops a covalent bond, an atom with a higher electronegativity is given a negative oxidation state.

A researcher wants to test the solubility (property of being dissolved) of salt in water as the temperature of the water increas

aev [14]

Have about 5 beakers all with different temperatures of water. Put in a teaspoon of salt at a time and when it stops dissolving stop adding and record how much salt it took. It should be more salt as the temperature rises. The independent variable is the waters temperature. The dependent variable is how much salt is used. Make sure that there is the same amount of water in each beaker. Or else it won’t work.
