Answer:

-1

Explanation:

The oxidation number of Na in NaCl is +1 and that of Cl is -1.

For simple ions, the oxidation number is the charge they carry.

When NaCl is oxidized we have;

NaCl → Na⁺ + Cl⁻

In this process, Na will lose an electron to become Na⁺ and thus isoelectronic with Ne, Cl will gain the electrons to become Cl⁻ and thus isoelectronic with Argon.

frez [133]

Upstream speed = S - 1
Downstream speed = S + 1

Average speed = total distance / total time

Average speed = (S - 1) + (S + 1) / 2
= S

S = 6 miles / 4 hours
S = 1.5 miles per hour
