http://www.dynamicscience.com.au/tester/solutions1/chemistry/energy/hesslawcoppersulfateactivity.html WebI got so confused with the moles etc with this Q that I gave up But the Hess's cycle has to have the same products-just difference in moles: the Bicarbonate has to be x 2 when you work out the number of moles. So instead of dividing the mass you have by only 84 you divide it by 168. then what you do is: You use the equation for the Hess's cyle: * D …
WebIt can be considered as enthalpy of solvation with the solvent being water. Hydration enthalpy is also called hydration energy and its values are always negative. For a … WebConstruct a Hess cycle for the dissolving of calcium nitrate. Use the cycle to calculate the lattice enthalpy of Ca(NO3)2. (The Hess cycle could also be drawn with the reaction representing lattice enthalpy going along the top line, as this is the unknown.) (LEH(Ca(NO3)2) = (hydH(Ca2+) + 2 × (hydH(NO3–) – (solH(Ca(NO3)2)
