Which reaction best represents the complete combustion of ethane?

The chemical equation for the combustion of ethane is written below.

Explanation:

Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.

The chemical equation for the combustion of ethane follows:

By Stoichiometry of the reaction:

2 moles of ethane reacts with 7 moles of oxygen gas to produce 4 moles of carbon dioxide and 6 moles of water

Hence, the chemical equation for the combustion of ethane is written above.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
