2017年8月2日 · So $\ce{Fe3O4}$ contains both Fe(II) and Fe(III) ions; twice as much Fe(III) as Fe(II). In the picture below, showing the crystal structure, green atoms are Fe(II) and brown atoms Fe(III). All Fe(III) atoms are linked with six O atoms, sharing 'half an electron' with each oxygen; all Fe(II) atoms are linked with four O atoms, and all O atoms ...

2023年10月15日 · Ma et al state, that crystalline $\ce{Fe3O4}$ (magnetite) is thermodynamically more stable than amorphous $\ce{Fe(OH)2}$. BTW, the stability of magnetite, and its adherence to iron, is used to protect steel from rusting. "Blueing... creates a layer of magnetite over the metal to prevent rust." See also this question.

2024年4月25日 · Iron(II,III) oxide $\ce{Fe3O4}$:... has a cubic inverse spinel group structure which consists of a cubic close packed array of oxide ions where all of the $\ce{Fe^2+}$ ions occupy half of the octahedral sites and the $\ce{Fe^3+}$ are split evenly across the remaining octahedral sites and the tetrahedral sites.

According to the following reaction, how much energy is required to decompose 55.0 kg of Fe3O4? The molar mass of Fe3O4 is 231.55 g/mol. Fe3O4(s) ? 3 Fe(s) + 2 O2(g) ?H°rxn = +1118 kJ There are 2 steps to solve this one.

Given the following equation: 3 Fe + 4 H2O → Fe3O4 + 4 H2 What is the mass of Fe3O4 that can be produced when 4.7 g of Fe react with 7.4 g of H2O? Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.

2016年4月6日 · Actually, Fe3O4 has a crystal structure (an extended geometrically regular array) of Fe(III), Fe(II) and oxide ions in which the oxide ions exist in a cubic close packed pattern with the Fe(II) ions located at half of the octahedral sites and the Fe(III) ions distributed evenly between octrahedral and tetrahedral sites. $\endgroup$

2023年5月1日 · The fact a compound has mixed oxidation numbers like $\ce{Fe3O4}=\ce{Fe^{II}Fe^{III}2O4}$ or $\ce{Pb3O4}=\ce{Pb2^{II}[Pb^{IV}O4]}$, so it cannot be expressed by a single integer oxidation number, does not alone make the compound non-stoichiometric. But deviations in composition, leading to rational atom ratios, do make such a …
