Zinc metal reacts with hydrochloric acid to produce zinc chloride and hydrogen gas as seen in the chemical equations below: Zn(s) + 2HCl(aq) === ZnCl2(aq) + H2(g)

What type of equation is described above?

F. Double Replacement

G. Single Replacement

H. Decomposition

J. Synthesis

2b2t

explanation:

2b2t

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.
