Explanation:
having no strongly marked or positive characteristics or features.
Combustion is a chemical reaction in which a hydrocarbon reacts with oxygen to form carbon dioxide (CO2) and water (H2O). In other words, all the carbons get converted to CO2 while all the hydrogens get converted into H2O.
Incomplete combustion however, results in the formation of carbon monoxide (CO) and H2O.
Methane is a hydrocarbon with a molecular formula CH4. Thus complete combustion of methane can be expressed as-
CH4 + 2O2 → CO2 + 2H2O
Ans (C)

Answer:
An area around a molecule that describes a region of space where the electrons that are shared between bonded atoms can reside
Explanation:
A molecular orbital is an area around a molecule that describes a region of space where the electrons that are shared between bonded atoms can reside.
Molecular orbitals are formed by linear combination of atomic orbitals of about the same energy. The number of atomic orbitals that are combined to give molecular orbitals is the same as the number of molecular orbitals formed. The build up of electrons in molecular orbitals also follow the Aufbau principle, Hund's rule and Pauli exclusion principle.
