Consider the reaction below. Zn(s) + Cu2+ (aq)--->Zn2+ (aq) + Cu(s)
Which half reaction correctly describes the oxidation that is taking place?
A)Zn(s)--->Zn2+ (aq) +e
B)Zn(s)--->Zn2+ (aq) + 2e-
C)Cu2+ (aq) + 2e--->Cu(s)
D)Cu2+ (aq)e Cuis)

B

Explanation:

Oxidation

Zn---> Zn2+ 2e

Reduction

Cu2+ + 2e >Cu

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
