The chemical equation Cu + HgBr2 -> CuBr2 + Hg

Detailed information about the reaction Cu + HgBr₂ -> CuBr₂ + Hg:
The above equation represents a chemical reaction between copper (Cu) and mercury(II) bromide (HgBr₂) resulting in the formation of copper(II) bromide (CuBr₂) and mercury (Hg).

Reaction conditions:
For the reaction to occur, direct contact between the substances listed in the reaction equation is necessary. Simultaneously, it is important to ensure suitable conditions such as temperature, pressure, pH level, and reaction environment.
Typically, this reaction takes place at room temperature and standard pressure.

Reaction process:
Copper (Cu) and mercury(II) bromide (HgBr₂) begin to react once they come into contact with each other. This process leads to the conversion of copper into copper(II) bromide (CuBr₂) and the release of mercury (Hg).

Observable phenomena:
When the reaction takes place, changes in the color of the reactant mixture can be observed. Copper(II) bromide (CuBr₂) has a light green color that is easy to see. Mercury (Hg), a metal with a bright silver color, appears in the form of small droplets or precipitates.
