Exam Review

11)      You know a solute has formed when the solute and the substance are at an equilibrium, meaning no more substance an be dissolved in the solution.  To create a supersaturated solution, a solution that can hold more crystals than the original equilibrium,  you have to first heat the solution to boiling point then add more substance while stirring.  This will allow the solution to hold more of the substance.  There are three factors that affect solubility, the polarity of the substance and the polarity of the solvent, temperature (the higher the temperature the more it can hold),  Pressure (the higher pressure can hold more solute in the solution)

31)    Draw and explain how a nuclear facility works.
