POST LABORATORY QUESTIONS
1. Specific to this experiment, list two reasons why your data contains an experimental
error.
a.
b.
2. A 15.00 gram sample of ammonium chloride (NH4CI) was dissolved in 100.00 grams
of water. How much heat is produced by the dissolution (absorbed from the solution) if
the solution temperature goes from 22.0 oC to 1.0 oC. The specific heat of the solution
is 4.18 J/g °C
3. 300.0 mL of a 2.500 M solution X was mixed with 300.0 mL of a 2.500 M solution Y
in a calorimeter. Both of the solutions were at the same temperature initially. Determine
the heat of neutralization (kJ/mole) if the temperature goes from 12.0 °C to 29.0 °C.
Assume a molar ratio of 1:1.The specific heat of the solution is 4.281 J/g °C. The
density of the mixture is 1.050 g/mL.
4. Sketch a crude time-temperature graph for an endothermic reaction.
