In the reaction c5h8 + __o2 → 8h2o + 5co2, what coefficient should be placed in front of o2 to balance the reaction? 5 8 9 no coefficient is needed

it is actually nine

screening

explanation:

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.
