Some sports ‘cold packs’ use the dissolution of ammonium nitrate as the cooling source.Here the solid ammonium nitrate package is broken, and cools as it dissolves. Calculate the final temperature of a cold pack which contains 100 g of NH4NO3 and 400 g water at 25 °C.Assume the specific heat of the ammonium nitrate solution is 4.0 J/g-C. NH4NO3 80.0 g/mol. NH4NO3(s) → NH4NO3(aq) DrHo = +25.7 kJ/mol

PLEASE ANSWER BOTH :) 11. Commercial cold packs consist of solid NH4NO3 and water. In a coffee-cup calorimeter, 5.60 g NH4NO3 is dissolved in 100.0 g of water at 22.0°C; the temperature falls to 17.9°C. Assuming that the specific heat capacity of the solution is 4.18 J/(g·K), calculate the enthalpy of dissolution of NH4NO3, in kJ/mol. Assume that the heat capacity of the calorimeter is negligible. (1) 24.5 kJ/mol           (2) −24.5 kJ/mol        (3) 25.9 kJ/mol          (4) −25.9 kJ/mol       ...

Compound Δ Hrxn (kJ/mol) NH4NO3 + 25.7 KCl + 17.2 NaOH -44.5 KOH -57.6 You are given 6.7 grams of an unknown salt. You dissolve it in 54.1 mL of water. As the salt dissolves, the temperature of the solution changes from an initial temperature of 26.9°C to a final temperature of 53.9°C. Based on the chart of ΔH values and the temperature change, you can determine which salt you have. What is the temperature change? Δ T = o...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...
