A 1.00 L solution contains 0.050 M NaCl and 0.050 NaBr. What is the solution concentration of chloride if 0.040 moles of AgNO3 is added? Assume that the total solution volume remains constant and Ksp AgCl = 1.77 x 10-10 and Ksp AgBr = 5.4 x 10-13. Our teacher never gave us a problem that had two Ksp, kinda threw me off.
The minimum frequency of light needed to eject electrons from a metal is called the threshold frequency, ?0. Find the minimum energy needed to eject electrons from a metal with a threshold frequency of 5.73 × 10^14 s-1.
solution of a weak monoprotic acid, pKa 2.346, is mixed with 37.3 ml of 0.0832M sodium hydroxide. What is the pH of the resulting not a simple buffer solution?
For example if your compound is water and you have the information the boiling point, Tb=(99.98 C), the enthalpy of vaporization= (40.65 kJ/mol) and the molar mass= 18.02g/mol.
Given that mercury has a Hvap of 59.11 kJ/mol and its normal boiling point is 356.7°C, calculate the vapor pressure in mm Hg at room temperature, 25°C.
