WebOct 18, 2024 · Al2O3(s) → 2Al(s) + 3 2O2(g) ;ΔH ∘ rxn = 1676 ⋅ kJ ⋅ mol−1 Explanation: Of course the enthalpy is quoted per moles of reaction of written. And another way I could represent this is as...... Al2O3(s) + 1676 ⋅ kJ → 2Al(s) + 3 2O2(g) WebAluminum Oxide = Al2O3 This means every mole of aluminum oxide contains two moles of aluminum. We must first convert our mass of aluminum oxide to moles of aluminum oxide: The molar mass of Al2O3 is 101.96 g/mole. We can divide the mass of our sample by the molar mass of the material to get the number of moles Al2O3.
Webal和浓硫酸反应方程式和钝化反应 2Al + 6H2SO4 → Al2 (SO4)3 + 3H2↑ 在这个方程式中，我们可以看出铝原子愿意失去三个电子，变成3+的离子状态，与硫酸根离子形成相应的盐。 同时，六分子的浓硫酸可以在这个反应中释放出六分子的氢离子，因此在反应中产生了三分子的氧化剂硫酸和三分子的还原剂氢气，氢气以气体的方式溢出容器。 4Al + 3O2 → …
