At constant volume, the heat of combustion of a particular compound is –3791.0 kJ/mol. When 1.479 g of this compound (molar mass is 142.16 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 6.637 °C. What is the heat capacity of the calorimeter? heat capacity: kJC

Chemical energy stored in the reactants is released as heat when the reaction is exothermic. For an exothermic reaction, the enthalpy change for a reaction is negative. Enthalpy, represented as H, is the heat content of a system. As it is a state function, it depends on the state of the system; hence, it is calculated in the form of change in heat content. Heat change, or enthalpy change, is represented as ΔH; ΔH is a measure of the heat...

ReviewI Constants1 Periodic Table Part A A calorimeter is an insulated device in which a chemical reaction is contained By measuring the temperature change. ΔΤ, we can calculate the heat released or absorbed during the reaction using the following equation: A calorimeter contains 35.0 mL of water at 13.5 °C . when 1.20 g of X (a substance with a molar mass of 61.0 g/mol) is added, it dissolves via the reaction X+20)-X(ag) and the temperature of the solution increases...
