Question

What is this balanced equation? MnO₄⁻(aq) + I⁻(aq)  I₂(s) + MnO₂(s)

Calculate values for the following cells. Which reactions are spontaneous as written (under standard conditions)? Balance the equations. Standard reduction potentials are found in the Standard Reduction Potentials table. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)

Your answer contains improper superscript or subscript formatting.

I got 2MnO₄^-(aq) + 6I^-(aq) + 4H₂O(l)  ⇌  3I₂(s) + 2MnO₂(s) + 8OH^-(aq)

but webassign is saying it's wrong.

edit: nevermind, figured it out. 2 MnO₄^-(aq) + 8 H⁺(aq) + 6I^-(aq)  ⇌  3 I₂(s) + 2 MnO₂(s) + 4 H₂O(l)
