If the temperature of a solution after the dissolution of ammonium nitrate in 60 mL water drops to 0 oC inside a calorimeter, would the solution freeze? Why or why not?
Homework Answers
Answer:-
The solution will not freeze because due the non volatile solute i.e. ammonium nitrate there depression in the freezing point of the solution.

There are a smallpackage of ammonium nitrate (NH4NO3) in water. When the inside bag is broken, the solute dissolves in the water. This dissolution requires energy and the water cools and freezes. I have done many experiments to find the best packs, and the market leader uses 300 g of the solute and 300 mL of water. It reaches a final temperature of -2 C. If I assume the dissolution processis so fast that it can be modelled as adiabatic,...

Consider the dissolution of 1.50 grams of salt XY in 75.0 mL of water within a calorimeter. The temperature of the water decreased by 0.93 oC. The heat capacity of the calorimeter is 42.2 J/oC. The density of the water (and the solution) is 1.00 g/mL. The specific heat capacity of the solution is 4.184 J/goC. Identify the surroundings. Group of answer choices Salt dissolving in the water Calorimeter Water Solution and calorimeter

The change in enthalpy for dissolving ammonium nitrate in water is 26 kJ/mol. Determine the amount of ammonium nitrate (in grams) that was dissolved in water to make 50.0 mL of solution if the temperature of a coffee cup calorimeter changes from 25.3°C to 21.5°C. Assume the density of the solution is 1.0 g/mL and the heat capacity of the solution is 4.2 J/g°C.

The dissolution of ammonium nitrate (NH4NO3) in water is a classic example of a solute that has an endothermic enthalphy of solution (ΔHsolution). What is (are) the "driving force" (driving forces) for the dissolution of NH4NO3? Formation of ion-dipole interactions only. Increasing entropy only. Formation of ion-dipole interactions and decreasing entropy. Formation of dispersion interactions and increasing entropy. Formation of dispersion interactions only
