Q1:
When solid ammonium nitrate dissolves in water, the solution becomes cold.
This is the basis for an “instant ice pack”:
When 3.21 g
of solid dissolves in
50.0 g of water
at
in a calorimeter, the temperature decreases to .
Assuming that the water has a specific heat capacity of :
Calculate the value of q for this reaction
What is the molar enthalpy for the dissolution of ammonium nitrate in water?
