Answer: Option (3) is the correct answer.
Explanation:
Arrhenius base are defined as the species which dissociate to give hydroxide or ions.
For example, when is dissolved in water then it dissociates into and ions.
Whereas , , and does not dissociate to give hydroxide ions.
Thus, we can conclude that compound is an Arrhenius base.
The resulting pressure of the gas after decreasing the initial volume is 3 atm.
<h3>What is
Boyle's Law?</h3>
According to the Boyle's Law at constant temperature, pressure of the gas is inversely proportional to the volume of the gas:
P ∝ 1/V
For the given question required equation is:
P₁V₁ = P₂V₂, where
P₁ = initial pressure = 1.5 atm
V₁ = initial volume = 2 L
P₂ = final pressure = ?
V₂ = final volume = 1 L
On putting all these values on the above equation, we get
P₂ = (1.5)(2) / (1) = 3atm
Hence required pressure is 3 atm.
