The oxidation-reduction reaction between iron metal and aqueous permanganate ions in acidic solution is 16 H + ( aq ) + 5 Fe ( s ) + 2 MnO 4 − ( aq ) → 2 Mn 2 + ( aq ) + 5 Fe 2 + + 8 H 2 O ( l ) At some temperature, the reaction proceeds at such a rate that 1.00 millimole of H + is consumed in 2 minutes 33.8 seconds. What is the (invariant) rate of this reaction in units of moles per second?

Definition Definition Chemical reactions involving both oxidation and reduction processes. During a redox reaction, electron transfer takes place in such a way that one chemical compound gets reduced and the other gets oxidized.
How many signals do you expect in the H NMR spectrum for this molecule?
Br Br
Write the answer below.
Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H
atoms that would contribute to the same signal as the H already highlighted red
Note for advanced students: In this question, any multiplet is counted as one signal.

Number of signals in the 'H NMR spectrum.
For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to
the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
