A sample of a compound weighing 416 grams decomposes into 143 grams of iron and 273 grams of chlorine. The percent composition of these products is *blank* iron and *blank* chlorine. Using these values, we can determine that the empirical formula of the compound is Fe*blank* Cl *blank*

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.
