A student dissolves 12.7 g of sodium hydroxide (NAOH) in 200. g of water in a well-insulated open cup. She then observes the temperature of the water rise from 22.0 °C to 39.5 °C over the course of 6.8 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NaOH(s) → Na (aq) + OH (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 3 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.
