Chemistry

1. A 15.00 gram sample of ammonium chloride was dissolved in100.00 grams of water. How much heat is produced by the dissolution(absorbed from the solution) if the solution temperature goes from22.0 C to 1.0 C. The specific heat of the solution is 4.18J/gC
2. 300.0 mL of a 2.500 M Solution X was mixed with 300.0 mL of a2.500 M Solution Y in a calorimeter. Both of the solutions were atthe same temperature initially. Determine the heat ofneutralization (kj/mole) if the temperature goes from 12.0 C to29.0 C. Assume a molar ratio of 1:1. The specific heat of thesolution is 4.281 J/ gC. The density of the mixture is 1.050g/mL.
3. Sketch a crude time-temperature graph for an endothermicreaction
4. Why, on an exothermic time-temperature graph, does thetemperature eventually fall?
