Two students were asked to determine the Kb of an unknown base. They were given a bottle with a solution in it. The bottle was labeled aqueous solution of a monoprotic strong acid. They were also given a pH meter, a buret, and an appropriate indicator. They reported the following data: volume of acid required for neutralization = 21.0 mL pH after 7.00 mL of strong acid added = 8.95 Use the students' data to determme the Kb of the unknown base.

In the year 1980, countries near the United States experienced an increase in acid precipi- tation. During this same year, the United States had an increase in the burning of fossil fu- els to power homes and vehicles. Which statement best describes how these two occurrences are related? The United States' emissions of sulfur dioxide and nitrogen dioxide increased as a result of a decrease in the burning of fossil fuels to power homes and vehicles, and wind pat- terns caused these emissions to travel, leading to the formation of acid precipitation in other areas. The United States' emissions of sulfur dioxide and nitrogen dioxide increased as a result of an increase in the burning of fossil fuels to power homes and vehicles, and wind pat- terns caused these emissions to travel, leading to the formation of acid precipitation in other areas.

To simplify the measurement of the acidity or basicity of a solution, the pH (hydrogen potential) measure was developed. The pH is given by the formula pH = - log H ], where H* is the concentration of hydrogen ions in moles per liter in the solution. Find the pH value of a solution for which H =0.0000375. The pH value of a solution is approximately | (Round to the nearest tenth as needed.)
If the pH and pOH values are the same, what is the mole fraction of HCI in the solution if the density of the solution is 1.07 g/mL? MW: MW: Cl-35.45 g/mol; H=1.01 g/mol; O=16 g/mol Express your answer in scientific notation with 4 decimal places using e. (Example: 0.0001 can be written as 1.0000e-4 or as 1.0000E-4. Spaces are not allowed.)
