The equation 4Ca3(PO4)2 -> 6CaO + 4P2O5 + O2

  1. Detailed information about the equation 4Ca3(PO4)2 -> 6CaO + 4P2O5 + O2 -> :
    The equation shows the decomposition of calcium phosphate (Ca3(PO4)2) when heated, forming calcium oxide (CaO), phosphorus pentoxide (P2O5), and oxygen gas (O2).

  2. Reaction conditions:
    The necessary condition for the reaction to occur is high enough temperature. Typically, the reaction takes place when the temperature reaches about 1676 °C (3050 °F).

  3. Reaction process:
    When calcium phosphate is heated to the required temperature, it decomposes to calcium oxide, phosphorus pentoxide, and oxygen gas. This reaction is a thermal decomposition reaction, which means a reaction in which a substance decomposes into two or more other substances due to heat.

  4. Observable phenomena:
    During the reaction, changes in the color and shape of the reactants can be observed, from the white solid of calcium phosphate to the white solids of calcium oxide and phosphorus pentoxide, along with the release of oxygen gas.
