What is the relationship between the change in enthalpy (H), specific heat capacity (Cp), and temperature change (T) in a system?
The relationship between the change in enthalpy (H), specific heat capacity (Cp), and temperature change (T) in a system is described by the equation H Cp T. This equation shows that the change in enthalpy is directly proportional to the specific heat capacity and the temperature change in the system.

What is the relationship between enthalpy, entropy, and free energy in a chemical reaction?
In a chemical reaction, enthalpy, entropy, and free energy are related. Enthalpy is the heat energy exchanged during a reaction, entropy is the measure of disorder or randomness, and free energy is the energy available to do work. The relationship between these three factors is described by the Gibbs free energy equation: G H - TS, where G is the change in free energy, H is the change in enthalpy, S is the change in entropy, and T is the temperature in Kelvin. This equation shows that for a reaction to be spontaneous, the change in free energy must be negative, meaning that the enthalpy change and entropy change must work together in the right direction.
How do you solve Hess's law problems?
write out the balanced equation that you need then write out formation equations (2-4) that will give you those reactants and products. manipulate the equations by reversing them or multiplying or dividing by whatever number. until you have what you need for the original equation. whatever you do to the equation, do it to the enthalpy for that equation. everything should add or cancel until you have the equation needed and you can add the enthalpies to get the enthalpy for that equation

What is melting equation?
The melting equation describes the phase transition of a substance from solid to liquid as it absorbs heat. It typically involves the relationship between temperature and pressure, often represented in the context of the Gibbs free energy, where the change in enthalpy equals the product of temperature and change in entropy. The equation can be expressed as ( \Delta G = \Delta H - T\Delta S ), where ( \Delta G ) is the change in Gibbs free energy, ( \Delta H ) is the change in enthalpy, and ( \Delta S ) is the change in entropy. At the melting point, the Gibbs free energy change is zero, indicating equilibrium between the solid and liquid phases.
