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?
Calculate, to 2 decimal places, the enthalpy change produced from the thermal decomposition of 126 g of magnesium carbonate, its molar mass is 84.313 g/mol, under constant pressure according to the given equation.
