Answer:

Explanation:
Molarity refers to a measure of concentration.
Molarity = moles of solute/Litres of solution
Molarity refers to number of moles of solute present in this solution.
In order to find a solution's molarity, use value for the number of moles of solute and the total volume of the solution expressed in liters
As molarity of 2.3 mol of Kl is dissolved in 0.5 L of water,
Molarity = 
<u>Answer:</u>
"Boyle's Law" is based on the graph that is shown below.
<u>Explanation:</u>
Boyle's law or Boyle – Mariotte law or Mariotte's law, is an experimental gas law that discusses how a gas's pressure tends to rise as the container volume start declining. This shows the relationship between pressure and volume for a fixed mass at a constant temperature, i.e., number of a gas molecules.This rule visualizes the actions of gas molecules in a confined space. This law can be understood from following equation:
p₁V₁ = p₂V₂
Above the product of the initial volume and pressure is equal to the product of the volume and pressure after a change.

Chemical reactions that release energy will not occur without a source of energy. So the answer is release.
