dT = (i)(Kf)(m) is the equation that can be used to model the freezing point depression.
dT represents the change change in temperature.
i represents the amount of ions formed from the dissolution of the solute.
Kf represents the constant of the freezing point depression of water.
m is the molality of the solute in solution.
dT = (3)(1.86 degC/m)(2.65m)
dT = 14.8 degC
0-14.8 degC = -14.8 degC
So the freezing point is -14.8 degrees C. The reason why this value was subtracted from zero is because the presence of a solute lowers the freezing point.

What is the freezing point of an aqueous 2.65 m calcium chloride CaCl2 solution?
-14.8
What ions are present in what ratio in a solution of aqueous calcium chloride?
The ions are: Ca2+ and Cl-; the ratio chloride ions/calcium ions is 2.
A precipitate will be formed when an aqueous carbonic acid solution is added to an aqueous solution of?
calcium hydroxide
What does the aq stand for?
Aqueous. (Dissolved in water) Example: CaCl2(aq)= Aqueous Calcium Chloride.
When anhydrous calcium chloride is kept in open air it forms an aqueous solution why?
CaCl2 is a hygroscopic substance that, if left open with oxygen, will absorb all the H2O from the atmosphere.
What is the freezing point of an aqueous 2.65 m calcium chloride CaCl2 solution?
-14.8
What is the balanced chemical equation for the reaction of aqueous calcium chloride with aqueous sodium carbonate to produce calcium carbonate precipitate in an aqueous sodium chloride solution?
The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl
What if an aqueous solution of sodium carbonate is reacted with an aqueous solution of calcium chloride balanced in standard form?
2NaCO3 + CaCl2 < > Ca(CO3)2 + 2NaCl
What is the freezing point of an aqueous 265 m calcium chloride CaCI2 solution the freezing point of pure water is 00 degrees Celsius and kf of pure water is -186 degrees Celsius over m?
-14.8 Celsius
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
What is the freezing point of an aquerous 2.65m calcium chloride Solution?
-14.8 degrees Celsius
What ions are present in what ratio in a solution of aqueous calcium chloride?
The ions are: Ca2+ and Cl-; the ratio chloride ions/calcium ions is 2.
An aqueous solution of calcium nitrate is mixed with an aqueous solution of sodium phosphate?
jj
What happen of mixed calcium chloride solution and sodium carbonate solution filtering and wash the residue with distilled water allow to dry adding hydrochloric acid?
Carbon dioxide gas is given out! Explanation: calcium carbonate precipitates from mixing calcium chloride solution and sodium carbonate solution, because it has low solubility in water. When it meets strong acid (HCl), it reacts to give out carbon dioxide while forming calcium chloride in the aqueous solution.
A precipitate will be formed when an aqueous carbonic acid solution is added to an aqueous solution of?
calcium hydroxide
What does the aq stand for?
Aqueous. (Dissolved in water) Example: CaCl2(aq)= Aqueous Calcium Chloride.
What forms when calcium chloride and water is mixed?
A solution of calcium chloride is formed.
