How can an unknown Hreaction be determined using Hess's law?
Enthalpies from reaction steps are added to determine an unknown Hreaction
How can an unknown H reaction be determined using Hess law?
To use Hess Law, one simply uses the known equations and their respective ∆H values, rearranges them as necessary to arrive at the target equation (unknown ∆H) and then adds the ∆H values to obtain the value for the target equation. This is possible because Hess Law applies to state functions which are independent of the path.

How does the Hreaction relate to the Hf of molecules involved in a reaction?
The enthalpy change of a reaction (ΔHreaction) is related to the standard enthalpies of formation (ΔHf) of the molecules involved through Hess's Law. Hess's Law states that the overall enthalpy change for a reaction is the sum of the enthalpy changes for a series of reactions that add up to the overall reaction. The ΔHf values represent the enthalpy change when one mole of a compound is formed from its elements in their standard states.

What is Hess's family situation?
Family: Son of Leon Hess (business executive) and Norma (maiden name unknown); married Susan Elizabeth Kessler.
How can an unknown triangle H reaction be determined using Hess's law?
To determine the unknown reaction of triangle H using Hess's law, you would need to consider a series of known reactions that add up to the desired reaction. By manipulating and combining these known reactions, you can derive the overall reaction for triangle H. This involves balancing the equations and adjusting their coefficients to ensure the conservation of mass and energy.
How can an unknown deltaH reaction be determined using Hess's law?
By manipulating known reactions with known enthalpy changes to create a series of intermediate reactions that eventually add up to the desired reaction whose enthalpy change is unknown. By applying Hess's law, the sum of the enthalpy changes for the intermediate reactions will equal the enthalpy change of the desired reaction, allowing you to determine its enthalpy change.
