What is the standard heat of formation for H2O?
The standard enthalpy of formation of H2O (l) is -286 kJ/mol and the standard enthalpy of combustion of ethane is -1560 kJ/mol.
How does H2SO4 dissociate in water?
When H2SO4 is dissolved in water it dissociates to produce ions. The H+ ions react with the water molecules to form the hydronium ions.
Why is Sulphuric acid formula?
Sulphuric acid is the most common acid that is used in various chemical experiments. It is a strong inorganic acid. The chemical formula of sulphuric acid is H2SO4. The molecular formula of sulphuric acid has 2 hydrogen atoms, 1 sulphur atom, and 4 oxygen atoms.
How do you find the heat of formation?
This equation essentially states that the standard enthalpy change of formation is equal to the sum of the standard enthalpies of formation of the products minus the sum of the standard enthalpies of formation of the reactants. and the standard enthalpy of formation values: ΔH fo[A] = 433 KJ/mol. ΔH fo[B] = -256 KJ/mol.
