False because you have to take it out and do it right
The correct answer is A. The conservationist credited with founding the Wilderness Society is Bob Marshall.
Bob Marshall was an American forester, botanist, traveler, climber, writer and social activist who advocated the preservation of unspoiled wildlife.
He actively contributed to the development and adoption of environmental regulations prohibiting the construction of roads in vast federal specially protected natural areas. In 1935 he became one of the founders of the public environmental organization The Wilderness Society and its main sponsor.
Today Bob Marshall is considered one of the main initiators of the wildlife movement in the United States. Several geographic features are named after him, including the Bob Marshall Wilderness Nature Reserve in Montana and the Marshall Mountain on the Adirondack Ridge.

<u>Answer:</u> The pH of the buffer is 4.61
<u>Explanation:</u>
To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:
![pH=pK_a+\log(\frac{[\text{conjuagate base}]}{[\text{acid}]})](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%28%5Cfrac%7B%5B%5Ctext%7Bconjuagate%20base%7D%5D%7D%7B%5B%5Ctext%7Bacid%7D%5D%7D%29)
We are given:
= negative logarithm of acid dissociation constant of weak acid = 4.70
![[\text{conjuagate base}]}](https://tex.z-dn.net/?f=%5B%5Ctext%7Bconjuagate%20base%7D%5D%7D)
= moles of conjugate base = 3.25 moles
![[\text{acid}]](https://tex.z-dn.net/?f=%5B%5Ctext%7Bacid%7D%5D)
= Moles of acid = 4.00 moles
pH = ?
Putting values in above equation, we get:
Hence, the pH of the buffer is 4.61
