CH3COOH < HF < HIO3 < HCl

<h3></h3><h3>What is Appendix C?</h3>

The appendix to this document known as Appendix C contains the technical requirements for evaluating the Facility in order to determine whether or not it complies with CEB's grid connection criteria.

acid strength -

The acid's potency changes depending on the solvent. An acid that is strong in water could be weak in a more basic solvent, and vice versa for an acid that is weak in water. The solvent S, which is more acidic than water, can take a proton, in accordance with the Brnsted-Lowry acid-base theory.

What happens when an electron absorbs energy?
kiruha [24]

Answer:

When an electron absorbs energy, it will move up from a lower energy level to a higher energy level, called the "excited state" of the negatively-charged subatomic particle.

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.

Which of the following would not cause an increase in the pressure inside a sealed container of neon gas?
r-ruslan [8.4K]

The pressure in a sealed container means the volume of container is fixed

so we cannot change the volume of container hence gas

The other factors which can affect the pressure are

a) moles of gas : if we increase the moles of gas the pressure of gas will increase

b) Temperature: if we increase the pressure of gas the pressure of gas will increase due to increase in kinetic energy

So the following cannot increase pressure

a) decrease in moles of gas

b) decrease in temperature of gas
