A balanced equation that represents an overall cell reaction is shown. Choose the cell notation which corresponds to the electrochemical cell that is described by this equation.

a) Sn2+(aq) + 2Cu+(aq) → Sn4+(aq) + 2Cu(s)

b) Pt(s) l Sn2+(aq), Sn4+(aq) ll Cu+(aq) l Cu(s)

c) Pt(s) l Sn2+(aq), Sn4+(aq) ll Cu+(aq), Cu(s)

d) Cu(s) l Cu+(aq) ll Sn2+(aq), Sn4+(aq) l Pt(s)

e) Pt(s) l Sn2+(aq), Sn4+(aq) ll Cu+(aq) l Pt(s)

i think that its a or b but im not suree

**** oops a is the actual reaction it should actually say:

Sn2+(aq) + 2Cu+(aq) → Sn4+(aq) + 2Cu(s)

a) Pt(s) l Sn2+(aq), Sn4+(aq) ll Cu+(aq) l Cu(s)

b) Pt(s) l Sn2+(aq), Sn4+(aq) ll Cu+(aq), Cu(s)

c) Cu(s) l Cu+(aq) ll Sn2+(aq), Sn4+(aq) l Pt(s)

d) Pt(s) l Sn2+(aq), Sn4+(aq) ll Cu+(aq) l Pt(s)
nvm i got it its a :)
