A student dissolves 12.3 g of ammonium nitrate (NH, NO,) in 300. g of water in a well-insulated open cup. She then observes the temperature of the water fall from 22.0 °C to 18.4 °C over the course of 8.1 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NH,NO, (s) NH (aq) + NO, (aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to 2 significant digits. Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known and published values for this reaction. O exothermic Is this reaction exothermic, endothermic, or neither? O endothermic O neither If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case. | kJ kJ Calculate the reaction enthalpy AHvn per mole of NH¼NO3: mol
