Delta G (written triangle G) = Delta H -T Delta S
Enthalpy is the measurement of total energy change of a reaction. The energy of bond formation and bond breaking can be used to calculate the bond enthalpy of the reaction. Bond enthalpy is the enthalphy change when 1 mol of bond is broken. Therefore the general equation to calculate the enthalpy change is energy of bond broken subtract by energy of bond formation.
The change in enthalpy between products and reactants in a reaction
The change in energy represented by a thermochemical equation is directly proportional to the number of moles in substances undergoing a change.
There is no equation, the law simply states that energy is not created or lost during anything.
Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be: A + B --> AB + Heat The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be: AB + Heat --> A + B To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.

If you consider the equation, E=mc2, you can see that an amount of mass can be considered as equal to an amount of energy. In other words, we could take all the mass in a nuclear reaction and figure out how much energy that represents. If you add that to the amount of energy present at the same time, you get a summation of energy (some of which is mass represented as energy). That amount of energy does not change in a nuclear reaction.

There are different types of equations to calculate different types of energy.
according to energy heat equation e=mc^2 where c is speed we can calculate energy
The change in energy represented by a thermochemical equation is directly proportional to the number of moles in substances undergoing a change.
In general, cooling a solution slows the reaction. You can use the Arrhenius equation to figure out what effect a given temperature will have on a particular reaction (you'll need to know the activation energy).
The reaction in which energy is being released, and the overall energy change (enthalpy) is negative.
