Calculate how many moles of nh3 form when each quantity of reactant completely reacts according to the equation:
3n2h4(l)→4nh3(g)+n2(g)
2.6mol n2h4
4.05mol n2h4
63.8g n2h4

the answer would be a

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.
