The equation 2Hg2Br2 -> 4Hg + 2Br2

1. Detailed information about the equation 2Hg₂Br₂ -> 4Hg + 2Br₂ ->

The above equation represents the decomposition reaction of the compound mercury bromide (Hg₂Br₂) into mercury (Hg) and bromine (Br₂).

2. Reaction conditions

This reaction requires high temperature or exposure to light to stimulate. This is because mercury bromide has high chemical stability and is difficult to decompose under normal conditions.

3. Reaction process

When heated or exposed to light, the Hg₂Br₂ molecules will receive energy and decompose into mercury and bromine.

4. Phenomena that occur

In reality, this reaction is quite difficult to observe directly, because both mercury bromide and mercury do not have characteristic colors. However, you can see the transformation from the solid state of mercury bromide to the solid state of mercury and the characteristic brown color of bromine gas.
