A reaction between Mg and aqueous hydrochloric acid was performed to determine the heat of the reaction. A calorimeter with a heat capacity of 6.5 J/K was used. To the calorimeter 50.0 mL of 1.0 M HCI was added, the initial temperature was recorded and then 0.250 g of magnesium metal was added. The final temperature was then recorded. (Assume density of the solution is 1.03 g/mL; q = MCAT ; molar mass Mg = 24.31 g/mol; specific heat capacity of water = 4.184 J/g.K; q calorimeter = heat capacity x AT). The following data was recorded:Initial temperature:21.5°c ; Final Temperature: 45.1°c Calculate calorimeter (J) q solution (J) total amount of heat released (J), mol Mg, enthalpy of reaction in kJ/molor (q total/mol Mg). Just put the numerical values since units are already indicated. For the question, amount of heat released, there is no need to put the negative sign.
Your job is to design a cold pack using the endothermic process of dissolving NH4NO3. The dissolving process has a delta H value of +26.2kJ/mole. If you wanted to create a cold pack that contained 35g of H2O and that would drop in temperature by 5 degree C, how much NH4NO3 in grams would you have to use?

A 8.27 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72°C. After the salt has completely dissolved, the temperature of the solution is 28.54°C.

In an endothermic reaction the enthalpy of the reactants is greater than the enthalpy of the products. In an endothermic reaction, the energy required to break existing bonds is more than the energy released when new bonds form. In an exothermic reaction the energy required to break existing bonds is less than energy released when new bonds form. In an exothermic reaction the potential energy of the reactants is higher than the potential energy of the products and the energy term would be written on the product side of the equation.
