The chemical equation Cu + 2HgI2 -> CuI2 + 2Hg

Detailed information about the chemical equation:
The above chemical equation describes the reaction process between copper (Cu) and mercuric iodide (HgI₂). The result is the formation of copper iodide (CuI₂) and mercury (Hg).

Reaction conditions:
The specific conditions for this reaction may vary based on factors such as temperature, pressure, and the reaction environment. Typically, this reaction requires sufficiently high temperature and pressure.

Reaction process:

• Initially, copper and mercuric iodide are combined in a suitable reaction environment.
• With enough temperature and pressure, copper starts to react with mercuric iodide.
• The result is the formation of copper iodide and mercury.

Phenomena observed:
During the reaction process, changes in the color of the reaction environment can be observed. Copper (red) and mercuric iodide (red) combine to form copper iodide (black) and mercury (silvery white).
