A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 107 g of solution. The reaction caused the temperature of the solution to rise from 21.00 to 24, 70 °C. What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water. Enter your answer in kilojoules per mole of compound to three significant figures. • View Available Hint(s) ΑΣΦ

O 26 of 42 Constants Periodic Table Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant- volume (or "bomb") calorimeters. Part A A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer; energy changes in a reaction are observed via a temperature change of the solution in the cup. Bomb calorimeters are used to measure A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 107 g of solution. The reaction caused the temperature of the solution to rise from 21.00 to 24,70 C. What is the enthalpy of this reaction?

Enter your answer in kilojoules per mole of compound to three significant figures. combustion and other gas-producing reactions, where the reaction is observed in a strong, sealed vessel. The idea behind calorimeters is that if they are sufficiently insulated from the outside environment, any energy gained or lost in the chemical reaction will be directly observable as a temperature and/or pressure change in the calorimeter • View Available Hint(s) ΔΗ- kJ/mol Submit Naxt> Provide Feedback roblemiD-174388853&offset-prev VINS /myct/itemView
