A thermochemical equation shows the amount of heat given out or taken in when the reaction occurs.
CH4 + 2O2 = CO2 +2H2O, deltaH = -890 kJ/mol
Note delta H is negative when heat is given out, exothermic and +ve when endothermic.
Sorry can't do delta symbol - its a triangle!
A thermochemical equation includes information about the energy changes associated with a chemical reaction, such as enthalpy changes. A balanced chemical equation shows the reactants and products involved in a chemical reaction in their correct proportions. While a balanced chemical equation gives the stoichiometry of the reaction, a thermochemical equation provides additional information about the heat flow during the reaction.
1/8 S8 + O2 --> SO2 , delta H degree f = -296.9 kJ
A thermochemical equation includes the enthalpy change of a reaction, whereas a traditional chemical equation only shows the reactants and products involved in a reaction without considering energy changes. Thermochemical equations provide information about the heat absorbed or released during a reaction, while traditional chemical equations focus on the chemical identities of the species involved.
Including the physical states of reactants and products in a thermochemical equation is important because it provides additional information about the conditions under which the reaction occurs. The physical state can impact the enthalpy change of the reaction, as different phases have different enthalpies of formation. It helps to ensure that the reaction is balanced and allows for a more accurate determination of the heat transferred in the reaction.
The change in energy represented by a thermochemical equation is always given in units of energy, typically kilojoules (kJ) or kilocalories (kcal), and can be either exothermic (releasing heat) or endothermic (absorbing heat).

Because if it is not balanced it is not a true equation.
The reaction shown in the thermochemical equation is an exothermic reaction. This is because heat is a reactant (on the left side of the equation) and is released during the reaction.
The change in energy represented by a thermochemical equation is always given in units of energy, typically kilojoules (kJ) or kilocalories (kcal), and can be either exothermic (releasing heat) or endothermic (absorbing heat).
A + B + Heat → C, ΔH > 0
In a balanced chemical equation the number of molecules or atoms are specified.
A balanced chemical equation conveys the correct molar ratios of reactants and products in a reaction. Balancing a chemical equation upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed.
