Calculate the enthalpy of neutralization
WebWith Hess's Law though, it works two ways: 1. You use the molar enthalpies of the products and reactions with the number of molecules in the balanced equation to find the change in enthalpy of the reaction. That's what you were thinking of- subtracting the change of the products from the change of the reactants. 2. http://faculty.cbu.ca/chowley/chem1104lab/CalorimetryHO.pdf

If 50 m l of 1.6 M N a O H at 25.15 ∘ C is added to 25 m l of 1.79 M H C l at 26.34 ∘ C in a plastic foam cup calorimeter, what will be solution temperature be immediately after the ... WebThe enthalpy change of neutralization can be measured using a calorimeter, which is a device that measures the heat produced or absorbed during a chemical reaction. When an acid and a base are mixed in a calorimeter, the heat produced or absorbed during the reaction can be measured and used to calculate the enthalpy change of neutralization.
