Acidity of lactic acid = pKa = 3.85
Ca = 0.13M
Cs = 0.11M
<span>Henderson-Hasselbalch equation:</span>
pH = pKa + log(Cs/Ca)
pH = 3.85 + log(0.11M/0.13M) = 3.85 + log0,846 = 3.85 - 0.073 = <u>3.777</u>
Explanation: When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object. ... Thus, it is concluded that kinetic energy is the energy an object has due to its motion.
The answer would be 1.15 kilojoules. ope this helps.
