What are ionic compounds typically composed of?

Mashcka [7]

Ionic compounds are compound that contains ions held together by ionic bonds. They are made up of particles that are arranged in a repeating pattern. Ions are said to be packed in a regular crystalline structures in an arrangement with the least energy.

The temperature of a 5.00-L container of N2 gas is increased from 20 ∘C to 250 ∘C. If the volume is held constant, predict quali

Lana71 [14]

Answer: The average kinetic energy of the molecules will increase.

Explanation: We are given a container having fixed volume of 5.00L and there is an increase in the temperature of the cotainer from 20°C to 250°C.

The average kinetic energy is directly related to the temperature of the gas.

Mathematically,

$K.E._{avg}=\frac{3R}{2N_A}T$

From the above expression, as we increase the temperature of the gas, the average kinetic energy of the gas increases and vice-versa.

In the given question, the temperature of the gas is increasing and hence, the average kinetic energy of the molecules will also increase.
