A student dissolves 10.7g of sodium chloride NaCl in 200.g of water in a well-insulated open cup. He then observes the temperature of the water fall from 22.0C to 21.1C over the course of 4 minutes.
Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction:
NaCl(s) Na+(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 1 significant digit.
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.
