If a buffer solution is 0.220 M in a weak acid (Ka = 8.5 × 10-5) and 0.550 M in its conjugate base, what is the pH
Codeine, C18H21NO3, a commonly prescribed painkiller, is a weak base. A saturated aqueous solution contains 1.00 g codeine in 120 mL of solution and has a pH = 9.8. What is the Kb of codeine?
What would be the concentration of oxygen (in molarity units) if the gas had remained in the solution? C. Based on the above data, what is the rate of the reaction (in units of solution molarity per second)?
suppose .853L of H2 is collected at 15 degrees celcius and 782 mmHg. how much electricity in coulombs must have passed through the solution
Draw every stereoisomer for 1-bromo-2-chloro-1,2-difluorocyclopentane. Use wedge-and-dash bonds for the substituent groups, and be sure that they are drawn on the outside of the ring, adjacent to each other.
The amount of energy released by burning a fuel source, measured in energy per mass, is called the fuel value. If energy obtained from burning 1.23 pounds of butane (feul value is 10.85 kcal/g) is used to heat 126.5 kg of water at an initial tempe..
