Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."
One example is potassium phosphate, which can be formed by the reaction: 3 K2O + P2O5 => 2 K3PO4
Ternary Salt
synthesis
Carbon is a nonmetal. Thus this is a nonmetal oxide.

Phosphorus is not an oxide. It is an element. It is a nonmetal.
No potassium OXIDE is not: IT IS A METAL. IT IS A METAL.And it is not a NONmetal either.Potassium OXIDE K2O is a basic oxide: with water it forms (only) potassium hydroxide, KOHPotassium (elemental) is a alkali metal
Metal oxide reacting with a nonmetal oxide produces a salt.Examples:CaO + CO2 --> CaCO3PbO + SO3 --> PbSO42 NaO + H2O --> 2 NaOH
Metal oxide reacting with a nonmetal oxide makes a salt.Examples:CaO + CO2 --> CaCO3PbO + SO3 --> PbSO42 NaO + H2O --> 2 NaOH
