Explanation:
Tungsten is an chemical element
Answer:
A
Explanation:
You can see the top part looks kinda like methane, and the bottom part looks like hexane.
The pH of the solution of the given acid is 3.099
Let HX be the weak acid:
HX ⇌
+ 
For which:
= [
][
] / [HX]
If
lies in the range
we can assume that the equilibrium concentrations used in the expression are a good enough approximation to the initial concentrations.
Rearranging and taking negative logs of both sides gives:
pH = ![\frac{1}{2} [pK_{a} - loga]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5BpK_%7Ba%7D%20-%20loga%5D)
a is the concentration of the acid.
= -log (2×
) = 5.69
pH = ![\frac{1}{2} [5.69- (-0.508)]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5B5.69-%20%28-0.508%29%5D)
pH = 3.099
