How long will it take until 99% of the reactant have reacted? a galvanic cell has the following cell reaction: (c) dy (s) + 2 zn2+ (aq) → 2 zn (s) + dy+ (aq) ecell = 0.18 v (1) is this reaction spontaneous? which equation allows you to decide this? [1 mark] (ii) which compound is the anode? write the half reaction

the atomic mass is the bottom number on the element.

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.
