Ksp for Pbl2 is (7.1 x 10^-9) at 298 K. Calculate this salt's solubilty and the molarities of the ions in a saturated solution. Then use this information in the previous problem to find the solubilty of Pbl2 in a 0.10 M solution of Nal. Please show all work step by step.
suppose that a 5.0X10^-5 M solution of Ba(OH)2 is prepared. What is the pH of the solution?
During the late 1800's, hard rock miners replaced candles with carbide lamps for work in mine shafts. The lamps worked by dripping water onto calcium carbide that generated acetylene gas (H2C2) that was burned.
The resulting equilibrium solution has a pH of 10.56. What is the Ksp of the salt at 22 °C?
Considering the molecule HOOH. What happens to the overlap in the σ bond between the 2 O atoms as one hydroxyl group is rotated in a clockwise relative to the other hydroxyl group?
Given that the partition coefficient for a solute is K in a water-ether solvent extraction system, is it more effective to do one extraction with V mL of ether or three extractions with V/3 mL of ether
A hypothetical metal has a face-centered cubic unit cell and a density of 6.12 g/cm3. The molar mass of the metal is 143.2 g/mol. What is the atomic radius of this metal?
What volume (in mL) of a 1.420M NaOH solution is required to titrate 25.0mL of 4.50M HCl solution.
Following the equation for the combustion of 2C3H6O+8O2----->6CO2+6H2O+853.6 kcal. How much heat will be given off if 0.48 mol of acetone is burned completely?
Im really confused about spectroscopy and need an introduction on what it is and what these types of problems mean.
