The equation 2Zn3(PO4)2 -> 6ZnO + 4P2O5 + 2O2

  1. The chemical equation demonstrates the reaction process between Zinc Phosphate (Zn3(PO4)2) and Oxygen (O2). The result of this reaction is the formation of Zinc Oxide (ZnO) and Phosphorus pentoxide (P2O5).

  2. Reaction conditions: For the reaction to occur, Zinc Phosphate and Oxygen need to be placed under high temperature conditions. This helps stimulate the reaction process.

  3. Reaction process: When Zinc Phosphate is heated with Oxygen, it decomposes to form Zinc Oxide and Phosphorus pentoxide. This reaction is a type of chemical decomposition reaction, where a complex substance breaks down into simpler ones.

  4. Phenomena occurring: During the reaction process, there will be changes in colour and temperature. Zinc Phosphate is white, and when it reacts with Oxygen, the color changes to yellow due to the formation of Zinc Oxide. Furthermore, due to the release of heat, the system’s temperature will also increase.
