Hess's Law says the totalenthalpy changedoes not rely on the path taken from beginning to end. Enthalpy can be calculated in one grand step or multiple smaller steps. To solve this type of problem, organize the givenchemical reactionswhere the total effect yields the reaction needed. There ar...

Thank you everybody. I have tried to come up with some equationsbut when I test them the results never came out correctly. If the equation work on one alloy then it will not work on different alloy if the content of the element change or included in the alloy (such as W, Ti). ...
If the enthalpies of formation of propane, carbon dioxide, and water vapor are -103.9 kJ/mol, -393.5 kJ/mol, and -241.8 kJ/mol, what is the molar enthalpy change of reaction of propane? C3H8(g)+5O2(g)→3CO2(g)+4H2O(g)19
The work done by the compressor per unit mass of fluid equals the enthalpy change through the compressor. From the definition of enthalpy, calculate the specific work done by knowing the temperature change and the specific heat of the fluid at constant pressure: ...
Once the change in enthalpy is calculated, the routine TFIND can find the outlet temperatures. Since the recuperator heat transfer is dependent on the outlet temperatures through DTLM, HEATEX iterates between calculation of QREG using DTLM, and the revision of the outlet temperatures based on ...
