Answer:
The solubility product of calcium hydroxide is .
Explanation:
To calculate the concentration of acid, we use the equation given y neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is .
We are given:
Putting values in above equation, we get:
Molarity of calcium hydroxide solution = 0.01102 M
1 mole of calcium hydroxide gives 1 mole of calcium ions and 2 moles of hydroxide ions.
Solubility product is given by:
The solubility product of calcium hydroxide is .

The pressure of the compressed tank that was initially filled with hydrogen gas and has a pressure of 100kPa is pressure in the 250mL tank increases.
<h3>What is Boyle's law?</h3>
Boyle's law states that the observation that the pressure of an ideal gas is inversely proportional to its volume at constant temperature.
According to this question, a 1 L compressed tank is filled with hydrogen gas and has a pressure of 100kPa.
If all of the hydrogen gas is removed from the tank and pumped into a 250mL tank, which is smaller in volume, the pressure in the 250mL tank increases.
