What is the standard enthalpy of formation for N2 gas?
The standard enthalpy of formation for N2 gas is 0 kJ/mol.
What is the relationship between the standard enthalpy of formation and the standard enthalpy of reaction in chemical reactions?
The standard enthalpy of formation is the energy change when one mole of a compound is formed from its elements in their standard states. The standard enthalpy of reaction is the energy change for a reaction under standard conditions. The relationship between the two is that the standard enthalpy of reaction is the sum of the standard enthalpies of formation of the products minus the sum of the standard enthalpies of formation of the reactants.
What is the standard enthalpy for sodium sulfate?
The standard enthalpy for sodium sulphate is -1387kJ/mol.
What is the difference of enthalpy of formation and the enthalpy of combustion?
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
Calculate standard enthalpy of formation of FeO?
You shouldn't "calculate" a standard enthalpy of formation. The beauty of standard enthalpies of formation is that they are already calculated for you. That is why they are delineated by the term "standard" - they are standards that were figured out by chemists some time ago, that never change, and can be found in tables usually in textbooks and even on Wikipedia. If you need to know the standard enthalpy of formation of FeO, Google it. And let me know what you find...because I can't seem to find a set answer either. I have found one site that lists the standard enthalpy of formation of FeO to be 271.9 kJ/mol. But it hasn't been so evident in other places. No wonder you were confused! Good luck.

Why does oxygen gas not have an enthalpy of formation but ozone does?
Oxygen gas (O2) does not have an enthalpy of formation because it is an element in its standard state, which has an enthalpy of formation of zero by definition. Ozone (O3), on the other hand, is a compound and has a defined enthalpy of formation because it is formed from its elements in their standard states.
What is the standard enthalpy for sodium sulfate?
The standard enthalpy for sodium sulphate is -1387kJ/mol.
What is the standard enthalpy of formation of coconut oil?
The standard enthalpy of formation of coconut oil is not a well-defined value as it is a complex mixture of triglycerides, which are composed of various fatty acids. The enthalpy of formation of each individual fatty acid can be determined, but not for coconut oil as a whole.

What is the best definition of the enthalpy of formation Hf?
The enthalpy of formation (ΔHf) is the heat associated with the formation of one mole of a compound from its elements in their standard states. It represents the energy change when the compound is formed from its constituent elements under standard conditions.
Why is water identical to the standard enthalpy change of combustion of hydrogen.?
Water is identical to the standard enthalpy change of combustion of hydrogen because the combustion of hydrogen involves its reaction with oxygen to form water. The standard enthalpy change of this reaction is defined by the energy released when hydrogen combusts completely, which results in the formation of water as a product. Thus, the formation of water from hydrogen and oxygen under standard conditions directly correlates to the enthalpy change associated with the combustion process. Hence, the enthalpy change for the formation of water from its elemental components is equivalent to the enthalpy change of hydrogen combustion.
What is the difference between the enthalpy of formation and the enthalpy of reaction, and how do they relate to each other in chemical reactions?
The enthalpy of formation is the energy change when one mole of a compound is formed from its elements in their standard states. The enthalpy of reaction is the energy change in a chemical reaction. The enthalpy of reaction can be calculated by subtracting the sum of the enthalpies of formation of the reactants from the sum of the enthalpies of formation of the products.
