How many grams of hydrogen are produced if 120g of Na and 80.0 g of H2O are available​

i'm not sure

explanation:

i'll try whatever you got

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.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
