How many grams of BaCl2 can be made from 6 moles of Ba?

823.98

Explanation:

Since there is only one Ba per atom you simply times 1 by 6 to get the number of mols of Ba per atom, then you times this by the atomic mass of Ba on the periodic table

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.
