It should be the answer b but I’m not to sure
It has the slowest rotation of all planets.
like 240 earth days...in retrograde clockwise turns
Answer:
decreased by a factor of 10
Explanation:
pH is defined in such a way that;
pH= −log10(H)
Where H represents the concentration of Hydronium or Hydrogen ions
Given that pH is changed from 1 to 2,
By rearranging the above formula , we get 10−pH = H
- if pH=1,H=10−1=0.1M
- if pH=2,H=10−2=0.01M
Therefore, 0.1/0.01 = 10 and 0.1 > 0.01
Hence, the concentration of hydronium ions in the solution is decreased by a factor of 10
The answer you are looking for is A. If you need me to show you how I got the answer let me know. :)
C. C and Pb; Carbon and Lead being in the same group.
