Ocean water typically contains approximately 35 moles of salt ions dissolves in each 1000 moles of water. Assuming that ocean water has the same density as pure water, use this ratio to determine the molarity of the solution and then calculate the osmotic pressure between ocean water and pure water at 25 degrees Celsius.
Consider a saturated solution of calcium fluoride in 0.075 M potassium nitrate. Complete the following tasks, and then answer the question. (Note: Your textbook may not employ the terms Kspo and Ksp'. Please refer to the lecture notes.)
describe the mechanism of the reaction for the production of tetrachloromethane
Use the values of Ka1 = 0.056 and Ka2 = 5.4 x 10-5 to calculate the [OH-] in a 0.898 M solution of oxalic acid (H2C2O4). Use E notation and 3 significant figures.
Heat is now added until the water reaches a saturated vapor state. Find the initial volume, final pressure, work, and heat transfer. Any help would be appreciated, thanks in advance.
