First, let's define kinetic energy and potential energy.
<u>Kinetic</u>
- energy an object has due to motion
<u>Potential</u>
- energy an object has stored due to its position, charge, arrangement or other factors
Since the boy is walking down the street, the boy is in motion. Therefore, the energy must be <em>kinetic energy.</em>

Answer:
4.77 is the pH of the given buffer .
Explanation:
To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:
We are given:
= Dissociation constant of propanoic acid =
pH = ?
Putting values in above equation, we get:
pH = 4.77
4.77 is the pH of the given buffer .
