Explanation:
According to the Henderson-Hasselbalch equation,
pH = 
+ ![\frac{log[A^{-}]}{[HA]}](https://tex.z-dn.net/?f=%5Cfrac%7Blog%5BA%5E%7B-%7D%5D%7D%7B%5BHA%5D%7D)
Given values are pH = 6, = 8
Putting given values into the above equation as follows.
6 = 8 + ![\frac{log [A^{-}]}{[HA]}](https://tex.z-dn.net/?f=%5Cfrac%7Blog%20%5BA%5E%7B-%7D%5D%7D%7B%5BHA%5D%7D)
= -2
![\frac{[A^{-}]}{[HA]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BA%5E%7B-%7D%5D%7D%7B%5BHA%5D%7D)
= antilog -2
= 0.01
But according to the question, we need protonated to deprotonated ratio of ![\frac{[HA]}{[A^{-}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BHA%5D%7D%7B%5BA%5E%7B-%7D%5D%7D)
= 
= 100
Thus, we can conclude that ratio of the protonated to the deprotonated form of the acid is 
.
Answer:
E
Explanation:
The answer woul be E because elements are made of one type of atoms
The correct answer among the choices listed is option B. Most of the nonmetals found are found in the right side of the periodic table. There are seventeen nonmetal elements that can found on that side. Nonmetal elements are poor conductors of heat and electricity.
Answer:
36000 centimeters
Explanation:
If the average speed of a species of tortoise is 0.36 km/h, then it would be 36000 centimeters.
You don't "turn" it into energy; petroleum HAS stored energy (chemical energy).However, you can turn it into ANOTHER TYPE OF ENERGY; usually this is done by burning the petroleum, and using it to drive machinery.
Since burning fuels is wasteful (the efficiency is limited, in theory, to the Carnot efficiency of a heat engine), other options are being explored, such as chemical reactions in a fuel cell. But such technology is not yet used on a large scale.
