QuestionAnswer
osmotic pressure is ? a/ a light saber----b/pressure applied to a solution to prevent osmosis----c/pressure applied to a solution that decreases the boiling point of the osmosis-----d/depression constant b/pressure applied to a solution to prevent osmosis
The freezing point, boiling point, and osmotic pressure are called ?--- a/molal properties---b/colligative properties---c/ residual properties---d/klingon properties b/colligative properties
What is the freezing poin tof a solution that contains one mole of MgBr2?----a/0.00 oC----b/-1.86 oC----c/ -3.72 oC-----d/ -5.58 oC d/ -5.58 oC
As the molality of a solution increses, its osmatic pressure? a/ increases-----b/ decreses----c/ remains the same b/ decreses
what is the boiling point of a 2 m NaCl?----- a) 301 degrees fahrenheit-----b) 208 oCdegrees celsius ---- c)OCC kalvin------d)108 degrees celsius b) 208 oC
What is osmosis?---a/mass mass volume---/b the movement of solvent molecules form an area of high solvent concentration to an area of low solvent cocentration---c/the pressure that must be applied to a solution to prevent osmosis b/ the movement of solvent molecules form an area of high solvent concentration to an area of low solvent cocentration--
What is the molal boiling point elevation constant?---a/ mass of hydrogen squared---b/altitude of the sun --c/ amount a one molal solution of non electrolyte wil raise the boiling point of a solution d/ energy equals mass times the speed of light c/ amount a one molal solution of non electrolyte wil raise the boiling point of a solution
