A student dissolves 13.8 g of ammonium chloride (NH4Cl) in 250. g of water in a well-insulated open cup. She then observes the temperature of the water from 21.0 °C to 17.3 °C over the course of 6.3 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NH₂Cl(s) → NH(aq) + Cl¯ (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 t correct number of 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. Is this reaction exothermic, endothermic, or 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. Calculate the reaction enthalpy AH per mole of NH Cl.…
Adding 4.88 g of NH4NO3 (s) to 140 g of water in a coffee-cup calorimeter (with stirring to dissolve the salt) resulted in a decrease in temperature from 19.0 °C to 16.7 °C.
