The pH unit has 10x as many hydrogens ions as the unit above.
Ex: A pH of 5 would have 10x more hydrogen ions than a pH of 6
and 100x more than if it had a pH of 7.
With a pH of 9 and 3, this is equivalent to 10⁶
So your answer should be:
1,000,000
Answer:
C. T>617 K
Explanation:
We are given that
We have to find the temperature at which the reaction is spontaneous.
When
Therefore, the reaction is spontaneous at certain range of temperature.
Option A is not true.
When is negative, then the reaction is spontaneous.
When T<50
Suppose T=49 K
Therefore, .Hence, the reaction is not spontaneous.
Option B is wrong.
C.T>617K
Suppose T=618 K
Therefore, .Hence, the reaction is spontaneous.
So, option C is true.
D.T<617 K
Suppose T=616 K
Therefore, .Hence, the reaction is not spontaneous.
So, option D is not true.
Question: What is shown on the photo above?
Choices: A) An aquifer B) A sinkhole C) A watershed D) Karst topography
Answer: <u>It's C) A watershed because A. is where the water is underground, B. is a sinkhole and it has a big hole that is big or sometimes small, and D. Is where it has a little crack in it and it goes underground. </u>
