WebJan 2, 2015 · In the compound Al2O3 oxygen is oxidized to minus 2. You will note that two aluminum times plus 3 is 6, and 3 oxygen times minus 2 is minus 6; thus the combination of aluminum and oxygen... WebJan 7, 2024 · So it is characterized by the following chemical reactions: 1. the reaction of aluminum oxide with aluminum: 4Al + Al2O3 ⇄ Al2О (t = 1450 °C). The reaction produces aluminum oxide. 2. the reaction of aluminum oxide with carbon: 2Al2O3 + 9C → 2Al4С3 + 6СО (t = 1800 °C). The reaction produced a salt – carbide aluminium oxide and carbon.

WebWe know that the Oxygen in the Ozone ( O 3) is all different having -1, 0, and +1 as their oxidation state. Oxidation state of Oxygen = -1 + 1 + 0 So, the sum of Oxidation states of all the 3 Oxygen will be 0. Therefore, the Oxidation number of Oxygen atoms in Ozone ( O 3) is 0. 4 Download BYJU'S The Learning App WebMay 4, 2015 · Determine the oxidation state of oxygen in Al2O3 : Include the sign (+ or -) as needed.
