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 is a titration carried out?
In a titration, a solution of known concentration (the titrant) is slowly added to a solution of unknown concentration until the reaction is complete. This reaction can be monitored using an indicator that changes color when the reaction is complete. The volume of titrant required to complete the reaction can then be used to determine the concentration of the unknown solution.
How can a titration help you to determine the concentration of an unknown substance?
In a titration, a known concentration of a substance (titrant) is added to the unknown substance until a chemical reaction reaches completion. By measuring the volume of titrant required to reach a specific endpoint, the concentration of the unknown substance can be calculated using the stoichiometry of the reaction.
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.

What is a titration reaction?
A titration reaction is a chemical technique used to determine the concentration of a substance in a solution. It involves the gradual addition of a known concentration of another substance, called the titrant, to the solution until a reaction is complete. The endpoint of the reaction is usually detected using an indicator or an instrument, allowing for the calculation of the concentration of the unknown substance.

How can one determine the equilibrium concentration from the initial concentration in a chemical reaction?
To determine the equilibrium concentration from the initial concentration in a chemical reaction, one can use the equilibrium constant (K) and the stoichiometry of the reaction. The equilibrium concentration can be calculated by setting up an ICE (Initial, Change, Equilibrium) table and solving for the unknown concentration at equilibrium using the given initial concentration and the equilibrium constant.
