The volume of an ideal gas in a container is 2.0 L what will be the volume of the gas if the pressure on the container is doubled while the temperature is reduced from 400 K to 200 K

0.5L

Explanation:

To undestand this question you must know two laws: Boyle's law and Charle's law.

Boyle's law states the pressure of an ideal gas is inversely proportional to volume it occupies.

Charle's law states the volume of an ideal gas is directely proportional to absolute temperature.

Thus, when the pressure of 2.0L of gas is doubled, the volume is halved to 1.0 L. Then as the temperature is decreased also in halved from 400K to 200K, the volume is halved from 1.0L to 0.5L

is there any options? maybe im just not seeing them but i need the options to

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
