fe2o3 + hcl co fe2o3 While iron can have oxidation states ranging from − 4 to + 7, its most common oxidation states are + 2 and + 3. When forming ions, iron will lose two electrons from the 4s subshell, but it can also lose a third electron from its paired 3d orbital resulting in a + 3 oxidation state
fe2o3 + h2 The construction of p-n heterostructure caused by Fe-S bonds led to the close contact between α-Fe2O3 and MoS2, in which α-Fe2O3 was capped with few MoS2 layers, and enhanced the segregation and
fe2o3+co - Tác dụng với chất khử như H2, CO, Al, C… FeO + H2 → Fe + H2O. FeO + CO → Fe + CO2. 3FeO + 2Al → Al2O3 + 3Fe. 5.3 Tính khử - FeO là chất khử khi tác dụng với các chất có tính oxi hóa mạnh: 3FeO + 10HNO3 loãng → 3FeNO33 + NO + 5H2O. 2FeO + 4H2SO4 đặc → Fe2SO43 + SO2 + 4H2O. 6. Tính chất
