The equation 2Cr2O3 + 3SO2 -> 4CrSO4

1. Detailed information about the chemical equation:

The chemical equation 2Cr₂O₃ + 3SO₂ -> 4CrSO₄describesthereactionbetweenchromiumoxideCr₂O₃andsulfurdioxideSO₂toformchromiumsulfateCrSO₄.

2. Reaction conditions:

To occur, the reaction requires appropriate temperature and pressure conditions. In this case, the reaction typically happens at high temperatures and in an alkaline environment.

3. Reaction Process:

In this reaction, each Cr₂O₃ molecule reacts with an SO₂ molecule to form two CrSO₄ molecules.

Specifically, the reaction process could be described as follows:

• First, the Cr₂O₃ and SO₂ molecules come into contact with each other in the reaction environment.
• Next, these molecules react with each other, creating CrSO₄ molecules.

4. Occurring phenomena:

During the reaction, there could be changes in color, temperature, and/or mass of the reactants. The color of the reaction mixture may change due to the formation of chromium sulfate.
