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.

One can determine the charge for an unknown material by using negligible friction. One will then be able to compare reactions between different charges that are brought near the unknown material.

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.

The rate of a reaction is calculated using the concentrations of reactants.
Resistance can be determined by measuring the voltage across a component and the current flowing through it, then using Ohm's Law (R = V/I) to calculate the resistance. Alternatively, resistance can be determined by using a multimeter set to the resistance measurement mode to directly read the resistance value.
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.
