Al2Se3 + 3 H2O→ Al2O3 + 3 H2Se is the balanced and complete equation.
Aluminum selenide is a chemical compound that is also referred to as aluminum selenide or aluminum (III) selenide. Al2Se3 is its chemical composition. The +3-oxidation state of aluminum is present in it. Both aluminum and selenide ions are present. Al2Se3 is its chemical composition. The +3-oxidation state of aluminum is present in it. Both aluminum and selenide ions are present. Three electrons are lost by an aluminum atom when it transforms into an ion. Given that there are only 10 electrons, their value is deducted from the quantity of protons, leaving a positive three-digit difference. As a result, the positive charge of an aluminum ion is three, denoted by the symbol 3+.
