A student dissolves 11.3 g of sodium hydroxide (NaOH)in 300. g of water in a well-insulated open cup. She then observes the temperature of the water rise from 22.0 °c to 31.5 °C over the course of 8.9 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 te using measured data are digits.
