Enthalpy of combusion is energy change when reacting with oxygen. Enthalpy of formation is energy change when forming a compound. But some enthalpies can be equal.ex-Combusion of H2 and formation of H2O is equal

How do i get the heat of combustion of c25h52?
You're gonna need an enthalpy change of formation table.
How is the enthalpy of reaction related to the enthalpies of formation for the products and reactants?
The difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
Equation for the heat of formation of carbon disulphide?
C + 2S -> CS2 Enthalpy of formation is the change in enthalpy for the formation of a substance from its elements.
What is the specific enthalpy of combustion of ethane?
-51.88 kJ/g

Why does oxygen gas not have an enthalpy of formation but ozone does?
Ozone gas has enthalpy of formation. It is due to the high altitude.
What does the negative sign on the value of an enthalpy of formation indicate?
A negative enthalpy of formation indicates that energy is evolved.
Which represent(s) a chemical property?
· General chemical properties: - Pauling electronegativity - Period - Group - Flammability - Corrosivity - Heat of combustion - Enthalpy of formation Valence (oxidation states)

Chemical properties of matter?
is seen when one substance reacts with another substance
What is Enthalpy of formation of chloroform?
There are several different measures of enthalpy. See link for some information.
How bond formation and bond breaking related to enthalpy?
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.
What is the experimental molar heat of combustion of methane?
The standard enthalpy of combustion for methane is -890 kJ/mol.
What is an example that shows that the combustion of methane produces 802 kJmol of energy?
The enthalpy of combustion is determined by calorimetry.
