Silver tarnishes when exposed to oxygen and dihydrogen mono sulfide, The chemical reaction is as follows: 4Ag(s) + 2H2S(g) + O2--->2Ag2S(s) + 2H2O(l) Every household has some H2S in the air (it smells like rotting eggs), but there is usually only a small quantity. H2S is almost always a limiting reaction, If a silver spoon has 0.0030 moles of tarnish on it, how many moles of H2S was it exposed to?

ill try to . no promises tho.

explanation:

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.

your answer is c) plasma
