please use the photo attached for the information A student dissolves 12.9 g of ammonium chloride (\( \text{NH}_4\text{Cl} \)) in 300. g of water in a well-insulated open cup. She then observes the temperature of the water fall from 20.0 °C to 16.9 °C over the course of 4.6 minutes.Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction:\[ \text{NH}_4\text{Cl} (s) \rightarrow \text{NH}_4^+ (aq) + \text{Cl}^- (aq) \]You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to 2 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.*---**Is this reaction exothermic, endothermic, or neither?**- [ ] exothermic- [ ] endothermic- [ ] neither---**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.**\[ \_\_\_\_ \, \text{kJ} \]---**Calculate the reaction enthalpy \( \Delta H_{\text{rxn}} \) per mole of \( \text{NH}_4\text{Cl} \).**\[ \frac{\_\_\_\_ \, \text{kJ}}{\text{mol}} \]
