if 5.50 L of water vaporat 50.2 °C and 0.121 atm reacts with an excess of iron to produce iron(III)oxide and hydrogen gas, how many grams of iron(II) oxide will be produced? Enter your answer as a numerical value with no units.

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.

it is reliable if two scientists recorded it
