1. Detailed information about the equation 2Hg₃Sb₂ -> 2Hg₂Sb₂ + Sb₂ + O₂ -> :
   The aforementioned chemical equation illustrates the decomposition of the mercury and antimony compound (Hg₃Sb₂) into another compound of mercury and antimony (Hg₂Sb₂), antimony (Sb₂), and oxygen gas (O₂).

2. Reaction conditions:
   The reaction typically occurs when subjected to high temperatures to accelerate the reaction rate.

3. Reaction Process:
   Upon heating, the Hg₃Sb₂ compound will decompose into Hg₂Sb₂, Sb₂, and O₂.

4. Phenomena observed:
   During the reaction process, the generation of O₂ gas can be observed. The reaction products are new mercury and antimony compounds along with free antimony.

Note: This reaction needs to be conducted under strict control as both mercury and antimony are toxic substances, harmful to human health if directly exposed.

1. The above chemical equation shows the reaction between 2 molecules of Hg₃Sb₂ compound (Mercury Antimonit) to produce 2 molecules of Hg₂Sb₂ compound (Mercury Antimon), one molecule of Sb₂ compound (Antimon) and one molecule of O₂ compound (Oxygen).

2. Reaction conditions: This reaction requires heat and light to proceed, and is usually carried out at high temperatures.

3. Reaction process: When the temperature is raised, the Hg₃Sb₂ molecules will start to decompose, creating Hg₂Sb₂, Sb₂, and O₂ molecules. When the reaction is complete, we will obtain the compounds that have been produced.

4. Observed phenomena: During the reaction, a change in color can be observed, from the gray of Hg₃Sb₂ to the red of Hg₂Sb₂. Additionally, there may be smoke or steam rising from the reaction due to the release of heat and oxygen.

Note: This equation is not common and not often used in practical chemistry.
