Answer:
Potential energy is energy due to an object's height above the ground.
Potential energy = mass x gravity x height
Kinetic energy is energy due to the motion of the object.
Kinetic energy = 1/2 x mass x velocity²

Answer:
24 a 2.85
Explanation:
HCl is a powerful acid so it completely ioniz in water
The given molarity of sodium hydroxide solution = 2.0 M
The required concentration of sodium hydroxide is 65 mL of 0.6 M NaOH
Converting 65 mL to L:

Calculating the moles of NaOH in the final solution:

Finding out the volume of 2.0 M solution taken to prepare the final solution:

Therefore, 19.5 mL of 2.0 M NaOH solution and make it up to 65 mL to prepare 0.6 M NaOH solution.
