Answer: How long is the track?
Step-by-step explanation: Before you can know anything you need to know how long the track is so you can determine how many laps it will take to do a Kilometer.
PH
is a scale which measures the acidity or alkalinity of a solution. It ranges
from a level of 1 to 14. A pH which range from 1 to 6 represents an acidic
substance. At pH of 7, signifies the solution is neutral. And at a pH of 8-14
represents a basic solution. pH is expressed as the negative logarithm of the
concentration of hydronium ions. To determine the factor of how the pH will change, we use the definition of the pH.<span>
pH = -log [H+]
5.50 = -log [H+]
[H+] = 10^-5
2.00 = -log [H+]
[H+] = 10^-2
</span>10^-5 / 10^-2 = 0.001
The rate of reaction would change by a factor of 0.001 as the pH change from 5.5 to 2.0
