Why fe3o4 is formed?
Production of Iron (II, III) oxide: Schikorr reaction – This reaction is to convert iron(II) hydroxide (Fe(OH)2) into iron(II,III) oxide (Fe3O4). Under anaerobic conditions, ferrous hydroxide (Fe(OH)2) undergoes oxidation with water to form magnetite and molecular hydrogen.
What is the enthalpy of h2?
H(g) – 218 kJ/mol.

What is the symbol for standard enthalpy of formation?
ΔH f
The standard enthalpy of formation is a measure of the energy released or consumed when one mole of a substance is created under standard conditions from its pure elements. The symbol of the standard enthalpy of formation is ΔH f.
How do you calculate the standard enthalpy change of 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.
What is meant by enthalpy of reaction?
The Heat of Reaction (also known and Enthalpy of Reaction) is the change in the enthalpy of a chemical reaction that occurs at a constant pressure. It is a thermodynamic unit of measurement useful for calculating the amount of energy per mole either released or produced in a reaction.
What is the standard enthalpy of formation of Fe2O3?
Determine the standard enthalpy of formation of Fe 2 O 3 (s) given the thermochemical equations below. Fe (s) + 3 H 2 O (l) → Fe (OH) 3 (s) + 3/2 H 2 (g) Δ rH ° = +160.9 kJ/mol-rxn
What is the formula for the compound Fe2O3?
Iron (III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron (II) oxide (FeO) the rarer form, and iron (II,III) oxide (Fe3O4) which naturally as magnetite. InChI=1S/2Fe.3O
What is the standard state equation for F e2o3?
For F e2O3 the Standard State Equation would be represented as follows… 2F eo(s) + 3 2O2(g) => F e2O3(s); ΔH o f = −824.2 Kj mole For the reaction in the post it is showing 2 moles of F e2O3. Therefore, the ΔH o Rxn = 2 × ΔH o f = 2moles(− 824.2 Kj mole) = −1648.4Kj
