Help. What is the balanced chemical equation for the combustion of diesel?

The chemical equation of diesel fuel combustion is as follows, C13H28 + 20O2 → 13CO2 +14H2O. Combustion reactions are spontaneous yielding a -∆G. The reaction goes from 20 moles of O2 gas to 13 moles of CO2 yielding a -∆S. Combustion reactions break bonds between the molecules signaling an exothermic reaction or -∆H.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
