![A student dissolves 11.8 g of potassium chloride (KCl) in 200. g of water in a well-insulated open cup. He then observes the temperature of the water fall
from 20.0 °C to 16.8 °C over the course of 3.5 minutes.
Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction:
KCI(s)
K"(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 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.
