In a synthesis reaction one reactant contains 346 j of chemical energy and one reactant contains 153 j of chemical energy. the product contains 435 j of chemical energy. because energy is conserved. what energy change occurs during the reaction? a) 64 j of energy is released b) 242 j of energy is absorbed c) 64 j is absorbed d) 242 j of energy is released

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.
