An acid with a p K a of 8.0 is present in a solution with a pH of 6.0. What is the ratio of the protonated to the deprotonated f
olga2289 [7]

Explanation:

According to the Henderson-Hasselbalch equation,

                  pH = pK_{a} + \frac{log[A^{-}]}{[HA]}

Given values are pH = 6, pK_{a} = 8

Putting given values into the above equation as follows.

                   6 = 8 + \frac{log [A^{-}]}{[HA]}

                   \frac{log[A^{-}]}{[HA]} = -2

                   \frac{[A^{-}]}{[HA]} = antilog -2

                                         = 0.01

But according to the question, we need protonated to deprotonated ratio of \frac{[HA]}{[A^{-}]}

            \frac{[HA]}{[A^{-}]} = \frac{1}{0.01}

                     \frac{[HA]}{[A^{-}]} = 100

Thus, we can conclude that ratio of the protonated to the deprotonated form of the acid is \frac{100}{1}.

ahrayia [7]

24

Explanation:

An atom is the smallest indivisible particle of any matter. Atoms are distinct and distinguishable from one another and are called elements:

                             CH₃(CH₂)₅0CH₃

 There are 3 different kinds of atoms in the compound above called  

elements

                               Carbon

                               Hydrogen

                               Oxygen

 In the compound the subscripts gives the number of atoms:

                                C - 7

                                H - 16

                                0 - 1

    Number of atoms in the compound is 24.
