Answer 1

The charges present on the following ionic compounds are Ca²⁺, Mg²⁺, Cs⁺, Sc⁺, Al³⁺, S²⁻, F⁻, O²⁻, Cl⁻.

Ionic compounds are held together by ionic bonds are classed as ionic compounds. Elements can gain or lose electrons in order to attain their nearest noble gas configuration. The formation of ions (either by gaining or losing electrons) for the completion of octet helps them gain stability.

In a reaction between metals and non-metals, metals generally loose electrons to complete their octet while non-metals gain electrons to complete their octet. Metals and non-metals generally react to form ionic compounds.

Ionic compounds include salts, oxides, hydroxides, sulphides, and the majority of inorganic compounds. Ionic solids are held together by the electrostatic attraction between the positive and negative ions.

A gas at a pressure of 2.0 atm occupies a volume of 20 liters. If the volume is decreased to 10 liters and the pressure is increased to 4.0 atm, what will be the final volume of the gas?

Answers

The initial condition of the gas can be expressed using the combined gas law:

P1V1 / T1 = P2V2 / T2

where P1 = 2.0 atm, V1 = 20 L, and T1 is the initial temperature (which we will assume remains constant).

If the volume is decreased to 10 L and the pressure is increased to 4.0 atm, the new conditions can be expressed as:

P2 = 4.0 atm, V2 = ?, and T2 = T1

We can rearrange the combined gas law to solve for V2:

V2 = (P1V1T2) / (P2T1)

Plugging in the given values, we get:

V2 = (2.0 atm x 20 L x T1) / (4.0 atm x T1) = 10 L

Therefore, the final volume of the gas is 10 liters.
