Which occurs in the half-reaction Na(s) → Na+ + e−? *

A. Na(s) is reduced
B. Na(s) is oxidized
C. Na(s) gains electrons
D. Na+ is oxidized

A. Na(s) is reduced

Explanation:

In order for reduction to occur, the atom must gain an electron. And in this reaction, the Na(s) went from a 0 to +1

**Remember: Lose Electrons = Oxidized and Gain Electrons = Reduced

the dissolution of polymer can be thermodynamically described in 2 steps.

you need to stop taking that class
