The given options are;

(1)Oxygen has a melting point of 55 K.

(2) Oxygen can combine with a metal to produce a compound.

(3) Oxygen gas is slightly soluble in water.

(4) Oxygen gas can be compressed.

The statement that express the chemical property of oxygen from the question is that combination of Oxygen with a metal will  produce a compound.

  • Oxygen can be regarded as one of the non metal with chemical formula O2
  • One of the chemical property of oxygen (O2)  is it's reaction with metal, when reaction occurs between oxygen and a metal, a metal oxide will be formed.
  • The general equation goes thus

(metal + oxygen → metal oxide)

  • When reaction occur between oxygen and iron which is a metal, iron Oxide is formed, which is a compound the reaction goes thus

(4Fe+ 3O2 → 2Fe2O)

  • Rust is formed when there is exposure of iron to air.

Therefore, reaction of oxygen with metal will give a compound, hence option 2 is right
