Instant cold packs, often used to ice athletic injuries on the field, contain ammonium nitrate and water separated by a thin plastic divider. When the divider is broken, the ammonium nitrate dissolves according to the following endothermic reaction: NH4NO3(s)-->NH4 ^+(aq) + NO3^-(aq). In order to measure the enthalpy change for this reaction, 1.25 g of NH4NO3 is dissolved in enough water to make 25.0 mL of solution. The initial temperature is 25.8 degrees C and the final temperature (after the...

We did a lab where we dissolved calcium chloride and ammonium nitrate in water (calorimeter), and used the temperature change of the water to calculate the molar enthalpy of solution for each compound. I got -68.6kJ/mol for calcium chloride and +27.6kJ/mol for ammonium nitrate. There is a section in our lab report that states, "discuss the relationship between the responding and manipulated variable, and give reasons as to why this relationship exists." Our teacher told us that the manipulated variable...

Question 3 1 pts The heat of solution of ammonium nitrate is 26.2 kJ/mol. When ammonium nitrate solid is dissolved in water at room temperature the beaker containing the solution will start out getting colder, but will soon get very hot will likely feel warm to the touch will likely feel cold to the touch will need to be large enough to hold the extra heat. No transfer to heat

Suppose 0.756g of barium nitrate is dissolved in 200.mL of a 26.0mM aqueous solution of ammonium sulfate. Calculate the final molarity of nitrate anion in the solution. You can assume the volume of the solution doesn't change when the barium nitrate is dissolved in it. Be sure your answer has the correct number of significant digits. (M)
