18. Which of the following solutions has the lowest freezing point?lowest freezing point. which of the following aqueous liquids will have the lowestfreezing point? A. pure water..(the freezing point is 0 C right?) but anyway,it has 3 ions i think.B. sucrose is a molecule so it shouldn't matter, but putting the.60m confuses me, same for E glucoseC.Calculate the freezing point of a 0.09500 m aqueous solution of glucose. The molal freezing-point-depression constant of water is 19. A 2.05 m aqueous solution of some unknown had a boiling point of 102.1 °C. Which one of the following could be the unknown compound?freezing point of water gets lowered by 1.86 degrees cellsius for each mole of solute particles in solution. At what temperature LPG Gas Freeze?8-27. Which of the following liquid systems would be expected to have the lowest vapor pressure at room temperature? Given that pure water freezes at 0°C and the kF for water is 1.86°C/m, which of the following expressions gives the freezing point depression of the aqueous ammonia solution?

lowest freezing point - HomeworkLib

The boiling-point elevation equation is as follows: where the variables are as described above. The important variable here is the van't Hoff factor, which is When we dissolve something in water then it will certainly lower its freezing point. This lowering in freezing point depends upon the number of...Which of the following liquids will freeze? FREEZING POINT Change in phase from liquid to solid Why? When energy is taken out from a liquid, particles slow down until forces of The freezing point of water becomes lower as more particles are added until the point where the salt stops dissolving.Depression in freezing point is a colligative property which depends upon the amount of the solute. ΔTf =i×kf ×m. where Tf is the change in freezing Also, 1% NaCl will have Van't Hoff factor 2 and 1 % CaCl2 will have Vant Hoff factor i as 3. Thus 1% CaCl2 produces most ions and thus lowers the...has the lowest freezing point due to the highest moles of ions in solution. Explanation: plzzzz mark me as brainleist and follow me.

Which of the following liquids will have the lowest freezing point...

The freezing point is the temperature at which the liquid changes to a solid. By knowing the molality of a solution and the number of particles a compound will dissolve to form, it is possible to predict which solution in a group will have the lowest freezing point.Colligative properties: Freezing point depression. The depression in freezing point will depend on the total number of particles present, and the molality of those particles. We are given the molarity (not molality) of the different solutions so we'd really need the density of these solutions to compute molality.6) Which of the following liquids will have the lowest freezing point? 21) A solution of unknown nonvolatile electolite was prepared by dissolving 0.250 g of the substances in 40.0 g of CCl4. The boiing point of the resultant solution was 0.357 oC higher than the pure solvent .This is a step by step verification of the answer by our certified expert. What is the magnitude of the a) electric force, and b) gravitational force exerted by one proton on the other proton if the two particles are 3.80 x 10-10 m apart?the highest freezing point of the resulting solution? ammonium nitrate, cobalt(lll) acetate, aluminum sulfate, lead(ll) chlorate Here is the full question as it reads on my paper: The freezing I want to know what substance has the lowest freezing point that is liquid at room temperature. Thanks in advance.

According to colligative homes of solutes, melancholy of freezing point follows the number of particles produced upon solubilization. It is determined by the concentration of #CdI_2 #, which is 0.39 molal.

Theoretically #CdI_2# giving 3 ions consistent with system when dissolved in water, will have to give the second best possible freezing melancholy, at that concentration.

On the different hand #LiF# is in truth sparingly soluble in water (about 0.071 M), and cannot be dissolved at 0.sixty five molal.

So the resolution depends upon whether or not we need to constitute physical reality or resolution a theoretical query. [Sucrose and glucose give only one particle according to molecule.]
