The equation Zn + Na2SO4 -> ZnSO4 + Na2

1. Detailed information about the equation Zn + Na₂SO₄ -> ZnSO₄ + Na₂:
   This is a chemical reaction between the metal zinc (Zn) and the salt sodium sulfate (Na₂SO₄) to form the salt zinc sulfate (ZnSO₄) and the metal sodium (Na₂).

2. Reaction conditions:
   This reaction needs to be performed under normal temperature and pressure conditions and requires the presence of a catalyst to accelerate the reaction.

3. Reaction process:
   When zinc reacts with sodium sulfate, the metal zinc will replace sodium in the sodium sulfate salt to form zinc sulfate salt and sodium metal.

4. Phenomenon occurs:
   When the reaction occurs, you will see the color of the mixture change. Zinc will gradually dissolve, forming a light blue solution – the color of zinc sulfate salt. Also, the formation of sodium metal will be observed.

However, we need to note that, in reality, this reaction is very difficult to occur because zinc is not capable enough to replace sodium in sodium sulfate salt. Sodium metal also very easily reacts with air, potentially causing fire or explosions.
