1. Detailed information about the equation 2Hg₃P₂ -> 2Hg₂P₂ + P₂ + O₂ ->

This is a balanced chemical equation, representing the reaction process between the compound Mercury (II) Phosphide (Hg₃P₂) and Oxygen to form the compound Mercury (I) Phosphide (Hg₂P₂), Phosphorus (P₂) and Oxygen (O₂).

2. Reaction conditions

This reaction occurs when supplied with high temperature or high pressure.

3. Reaction process

When 2 molecules of Mercury (II) Phosphide (Hg₃P₂) react with Oxygen, they will dissociate and recombine to form 2 molecules of Mercury (I) Phosphide (Hg₂P₂), Phosphorus (P₂) and Oxygen (O₂).

4. Occurring phenomena

During the reaction process, it can be observed that the color of the reacting substance changes. Specifically, the white Mercury (II) Phosphide (Hg₃P₂) will turn into the black-gray color of Mercury (I) Phosphide (Hg₂P₂). Meanwhile, if the reaction happens in air conditions, it can be observed that combustion takes place, accompanied by the release of heat and light.

Note: The above is just an assumption about the reaction process based on the given chemical formula, the reality may have differences.

Regrettably, the information you requested is incorrect. The chemical equation you provided is unbalanced and does not involve O₂. You may be confusing different reactions.

The balanced chemical equation for the reaction between hydrargyrum phosphide (Hg₃P₂) and oxygen (O₂) to form mercury(II) phosphide (Hg₂P₂) and phosphorus (P) would be: 2Hg₃P₂ + O₂ -> 2Hg₂P₂ + P₂

1. This equation describes the oxidation reaction of hydrargyrum phosphide (Hg₃P₂) in the presence of O₂ to form mercury(II) phosphide (Hg₂P₂) and phosphorus (P₂).

2. Reaction conditions: The presence of oxygen is required, usually occurs at high temperatures.

3. Reaction process: Hg₃P₂ is oxidized by O₂, then forms Hg₂P₂ and P₂.

4. Phenomena occurring: During the reaction process, there will be a color change from the original substance to the reaction products. However, the specific phenomena depend on the actual conditions of the reaction.

Note: All chemical experiments should be conducted under the supervision of a specialist and comply with all safety rules.
