Carbon (C) and hydrogen (H2) should at least be present, as in paraffin (CnH2n+2):
CnH2n+2 + (2n+1)O2 --> nCO2 + (n+1)H2O

Why water is called a compound and air a mixture?
Compound have constant composition whereas mixture have variable. Now, water made by constant composition of hydrogen and oxygen (two atoms of hydrogen and one atom of oxygen) whereas air have many elements with variable composition.
