In chemistry, pH<span> is a numeric scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the concentration of hydronium ions. We calculate as follows:
pH = -log [H3O+]
pH = -log[</span><span>5.45 × 10–5 M]
pH = 4.3</span>
Answer:
Cupid nitrate is what I'm going for
Answer: Friction.
Explanation: Even though the driver has taken the foot off thr gas pedal, the acceleration of the car decreases and the friction continues.
The car slows down because the opposite force of friction continues to act and the acceleration in forward direction is continuous decreasing. Hence, the car slows down.
