A student dissalves 10.4g of sodium chioride ( NaCl) in 250.g of water in a well-insulated open cup. He then observes the temperature of the water fall from 23.0. C to-22.1 C over the course of 4.6 minutes. Use this data; and any intormation 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 pubished values for this reaction. \begin{tabular}{|l|c|} \hline Is uvis reaction exothermic, endothermic, or neither? & exothermic \\ \hline & endothermic \\ \hline 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 \\ \hline Calculate the reactien enthalpy Hmin per mole of NaCl. & kJ \\ \hline \end{tabular}
