Write the following inequality in interval notation 5

Attached is a word document that contains a picture of the drawing as well as the explanation.   let me know if the picture is not showing up or if my hand writing is too hard to read so that i can type the explanation in the comments for this answer. 

the major points for the answer was that the sn²⁺ is reduced while the cr is oxidized and that the sn electrode is the cathode while the cr electrode is the anode.   the electrons travel from the anode to the cathode while the anions travel from the cathode to the anode.

i hope this .   let me know if anything is unclear or if you want me to explain anything further.

Add them all together then u will get your answer
