The oxidation number of what atom or ion decreases in the following reaction?
Flauer [41]

The oxidation number of I (iodine) decreases the in the described chemical reaction from 0 to -1.

Explanation:

We have the following chemical reaction:

I₂ + 2 KCl → KI + Cl₂

The following atoms have a change in the oxidation number:

I with a 0 oxidation number (in I₂) goes to I with -1 oxidation number (in KI) by receiving 1 electron.

Cl with a -1 oxidation number (in KCl) goes to I with 0 oxidation number (in Cl₂) by losing 1 electron.

At a certain temperature the vapor pressure of pure heptane (C_7 H_16) is measured to be 170. torr. Suppose a solution is prepar
steposvetlana [31]

Explanation:

The given data is as follows.

       Pressure (P) = 170 torr,      mass of heptane (m) = 86.7 g

First, we will calculate the number of moles as follows.

          No. of moles = \frac{mass}{\text{molar mass}}

                        = \frac{86.7 g}{100 g/mol}

                        = 0.867 mol

Now, the number of moles of CH_{3}COBr are calculated as follows.

     No. of moles =  \frac{mass}{\text{molar mass}}

                           =  \frac{125}{122.9}    

                           = 1.07

Therefore, mole fraction of heptane will be calculated as follows.

     Mole fraction = \frac{\text{moles of heptane}}{\text{total moles}}

                           = \frac{0.867}{0.867 + 1.07}

                           = \frac{0.867}{1.937}

                           = 0.445

Now, we will calculate the partial pressure of heptane as follows.

            P_{A} = x_{A}P^{o}_{A}

                 = 170 \times 0.445      

                 = 75.65 torr

Thus, we can conclude that the partial pressure of heptane vapor above this solution is 75.65 torr.
