Question
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.
