A student dissolves 11.5 g of ammonium nitrate (NH4NO3) in 200. g of water in a well-insulated open cup. She then observes the temperature of the water fall from 20.0 °C to 16.6 °C over the course of 4 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NH4NO3(s) NH(aq) + NO, (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 the correct number of 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.

Alkali metals are often used to remove traces of water from organic solvents, such as diethyl ether. Because the reaction (see below) releases heat, care must be taken to make sure that the solvent does not "boil over". 2 Na(s) + 2 H₂O(1) ➜ 2 NaOH(aq) + H₂(g) a) Determine the standard enthalpy change for this reaction. Comment on the relative strength of bonding and/or interactions in the products vs reactants, and briefly explain how you decided this. Substance Na(s) H₂O(1) NaOH(aq) H₂(g) AHºf (kJ/mol) 0 -285.83 -469.15 0 b) How much heat (in kJ) is released via the reaction of 1.00 g of sodium metal with water? If this much heat is released into 275 g of diethyl ether initially at 25°C, will the solvent reach its boiling point? If so, how many grams of the ether will evaporate?
