The bonding and antibonding molecular orbitals which form from liner combinations of the 2 p z atomic orbitals in a homonuclear diatomic molecule. (The 2 p z orbitals are those whose lobes are oriented perpendicular to the bonding axis.) And these molecular orbitals differ from those obtained from linear combinations of the 2 p y atomic orbitals. (The 2 p y orbitals are also oriented perpendicular to the bonding axis, but also perpendicular to the 2 p z orbitals.) Concept Introduction: When two 2 pz orbitals combine in a side-by-side orientation in a homonuclear diatomic molecule, two molecular orbitals are formed—bonding and antibonding.

Interpretation: The bonding and antibonding molecular orbitals which form from liner combinations of the 2pz atomic orbitals in a homonuclear diatomic molecule. (The 2pz orbitals are those whose lobes are oriented perpendicular to the bonding axis.) And these molecular orbitals differ from those obtained from linear combinations of the 2py atomic orbitals. (The 2py orbitals are also oriented perpendicular to the bonding axis, but also perpendicular to the 2pz orbitals.)

"Water gas" is an industrial fuel composed of a mixture of carbon monoxide and hydrogen gases. When this
fuel is burned, carbon dioxide and water result. From the information given below, write a balanced equation
and determine the enthalpy of this reaction:
CO(g) + O2(g) → CO₂(g) + 282.8 kJ
H2(g) + O2(g) → H₂O(g) + 241.8 kJ
