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!

How is thermochemical equation different from a balanced chemical equation?
They specify heat flow for the reaction.
What is the difference between a thermochemical equation and a traditional chemical equation?
Thermochemical equation includes enthalpy ( ΔH ) change in it.
What is the balanced thermochemical equation for SO2?
1/8 S8 + O2 --> SO2 , delta H degree f = -296.9 kJ
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is directly proportional to the number of moles in substances undergoing a change.
What information can you determine from the coefficients in this balanced chemical equation?
What information can you determine from the coefficients in this balanced chemical equation? Mg + 2HCl → MgCl2 + H2

Why is it important to keep balance in an equation?
Because if it is not balanced it is not a true equation.
What is the thermochemical equation for endothermic changes?
A + B + Heat → C, ΔH > 0
What is the thermochemical equation for the formation of 1.00 mol of liquid water?
H2 + 1/2o2 --> h2o
What information In a balanced chemical equation shows how many moles of a reactant are involved in the reactant?
In a balanced chemical equation the number of molecules or atoms are specified.
What information does the coefficients provide in a balanced equation?
The coefficient in a balanced equation tells you the ratio of moles/molecules/etc of one reactant to the other reactants, and to the products. It gives you the stoichiometry of the reactions.
