Answer:

The answer to your question is:

Explanation:

1) Increasing atomic radius:

Oxygen 74

Aluminum 143

Potasium 227

2) Increasing electronegativity

Neon -

Aluminum 1.61

Sulfur 2.58

Oxygen 3.44

3.-

Electronegativity: is the measure of the tendency of an atom to attract a pair of electrons.

Ionization energy: is the quantity of energy that an isolated, gaseous atom must absorb to discharged an electron, resulting in a cation.

4.-

Atomic radius increases as we move down on the periodic table.

Atomic radius is the distance from the center of a nucleus to the outer most shell containing electrons.

5.-

Sulfur = 1s² 2s² 2p⁶ 3s² 3p⁴

Neon = 1s² 2s² 2p⁶

Lilit [14]

Answer:It is necessary to use Kelvin for the temperature and it is conventional to use the SI unit of liters for the volume.

Explanation:

However, pressure is commonly measured in one of three units: kPa, atm, or mmHg. Therefore, can have three different values.

At 189k a sample of gas has a volume of 32.0cm. what does the gas occupy at 242k

sattari [20]

<h2>Answer:</h2>

At 189 K volume = 32.0 cm

As volume of gas is directly proportional to temperature.

As the temperature increase the volume of gas will also increase.

Volume at 1 K = 32/189

Volume at 242 K = 32/189 * 242 = 40.97 cm.

Gas occupy 40.97 cm volume at 242 K.

Explanation:

Given parameters:

Volume to Temperature ratio = 1.75

Temperature = 300k

Unknown:

Volume of the gas = ?

Solution:

We must carefully analyze and comprehend the detailed description of this experiment:

It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.

This implies that the pressure in the vessel is constant

This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.

Mathematically;

$\frac{V1}{T1} = \frac{V2}{T2}$
