[Review Topics] [References] CHEMWORK A solution is made by dissolving 29.7 g urea (CH4N20), a nonelectrolyte, in 275 g water. Calculate the vapor pressure of this solution at 25°C and 45°C. vapor pressure of water 25°C 23.8 torr 45°C 71.9 torr vapor pressure at 25°C = torr vapor pressure at 45°C = torr Submit Show Hints

We utilise the phrase "like dissolves like" when choosing the correct solvent for the recrystallization technique. Which of the following sentences accurately describes this principle? A. two compounds with the same type and strength of intermolecular forces will likely dissolve in each other B. two substances with the same type of intermolecular forces but of different magnitude are likely to dissolve in each other C. two substances that contain in their structure the same skeleton, but different functional groups are likely to dissolve in each other. D. options B and C E. options A and B

powders and granules dosage forms have faster dissolution rate than capsules and tablets  ,why?

A mixture of copper and tin, commonly called bronze is a homogeneous mixture or a ____________ solution.

Why is it best to cool a solution slowly as a solid crystallizes? impurities are more likely to crystallize as well when done quickly the solid obtained will have a higher purity when done quickly no solid will form when done quickly the solvent could start to boil again when done quickly

Why are density and viscosity of a solution not considered colligative properties?
