The equation Cr2O3 + 2Al -> 2Cr + Al2O3

The chemical equation Cr₂O₃ + 2Al -> 2Cr + 2Al₂O₃describesthereactionprocessbetweenchromiumoxide(Cr₂O₃)andaluminum(Al). The result of the reaction is the formation of chromium (Cr) and aluminum oxide (Al₂O₃).

Reaction condition: This reaction requires high temperature to proceed.

Reaction process: Initially, chromium oxide (Cr₂O₃) and aluminum (Al) are placed in a high-temperature container. When high-temperature gas is passed through, aluminum begins to react with chromium oxide, releasing heat and forming chromium and aluminum oxide.

Phenomena occur: When the reaction takes place, heat is released, making the reaction mixture very hot. The chromium product will rise to the surface of the reaction in the form of gray particles.
