# Writing Cell Reaction from Diagram with Unknown Metal Ions

CHEM-NBAS42

Consider the galvanic cell above with unknown metals $X$ and $Y$.

What is the balanced reaction for this cell?

A

$X_{(s)}+{Y^+}_{(aq)} \rightarrow Y_{(s)} + {X^{3+}}_{(aq)}$

B

$X_{(s)}+3{Y^+}_{(aq)} \rightarrow 3Y_{(s)} + {X^{3+}}_{(aq)}$

C

${X^{3+}}_{(aq)}+ 3Y_{(s)}\rightarrow 3{Y^+}_{(aq)}+ X_{(s)}$

D

${X^{3+}}_{(aq)}+ 3Y_{(s)}+3e^-\rightarrow 3{Y^+}_{(aq)}+ X_{(s)}+3e^-$

E

$3X_{(s)}+{Y^+}_{(aq)} \rightarrow Y_{(s)} + 3{X^{3+}}_{(aq)}$

F

$3{X^{3+}}_{(aq)}+ Y_{(s)}\rightarrow {Y^+}_{(aq)}+3X_{(s)}$
