Answer:
It should b KNO3
Explanation:
one Potassium (K) and three Nitrite (NO3)
The term that describes when a solvent is holding as much solute in solution as it is able for a given temperature is called supersaturated solution. A little disturbance to this solution some of the solute will crystallize or precipitate out since this solution is not stable.
The molecular formula of glucose:
C₆H₁₂O₆
The enthalpy change is negative.
The other statements are false because:
Can take place without a catalyst
Energy is given out to the surroundings.
Kinetic energy of products is higher.
Answer: The vapor pressure of a solution in which the mole fraction of the solute is 0.200 is 80.0 torr
Explanation:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= vapor pressure of pure solvent = 100.0 torr
= vapor pressure of solution = ?
i = Van'T Hoff factor = 1 for nonvolatile, nonelectrolyte solute
= mole fraction of solute = 0.200
The vapor pressure of a solution in which the mole fraction of the solute is 0.200 is 80.0 torr
