I do believe the answer is cell
Answer:
(i) +3.
(ii) Mn.
Explanation:
Hello,
(i)
Based on the diatomic ion, we solve for the unknown oxidation state of carbon, assuming that the oxygen works with -2, by a change balance:
![(C_2O_4)^{-2}\\(C_2^{x} O_4^{-2} )^{-2}\\\\2x-8=-2\\x=+3](https://tex.z-dn.net/?f=%28C_2O_4%29%5E%7B-2%7D%5C%5C%28C_2%5E%7Bx%7D%20O_4%5E%7B-2%7D%20%29%5E%7B-2%7D%5C%5C%5C%5C2x-8%3D-2%5C%5Cx%3D%2B3)
(ii)
We first must each ion's oxidation states as follows:
![2H^{+} Cl^{-}+ 2K^{+}Mn^{+7}O^{-2}_4 + 3H_2^{+}C_2^{+3}O_4^{-2} --> 6C^{+4}O^{-2}_2 +2Mn^{+4}O_2^{-2} + 2K^{+}Cl^{-} + 4H_2^{+}O^{-2}](https://tex.z-dn.net/?f=2H%5E%7B%2B%7D%20Cl%5E%7B-%7D%2B%202K%5E%7B%2B%7DMn%5E%7B%2B7%7DO%5E%7B-2%7D_4%20%2B%203H_2%5E%7B%2B%7DC_2%5E%7B%2B3%7DO_4%5E%7B-2%7D%20--%3E%206C%5E%7B%2B4%7DO%5E%7B-2%7D_2%20%2B2Mn%5E%7B%2B4%7DO_2%5E%7B-2%7D%20%2B%202K%5E%7B%2B%7DCl%5E%7B-%7D%20%2B%204H_2%5E%7B%2B%7DO%5E%7B-2%7D)
Then, for the reduction half reaction we identify the manganese as the element decreasing its oxidation state based on:
![Mn^{+7} +3e^{-}-->Mn^{+4}](https://tex.z-dn.net/?f=Mn%5E%7B%2B7%7D%20%2B3e%5E%7B-%7D--%3EMn%5E%7B%2B4%7D)
In addition, the carbon is oxidized from +3 to +4 (increase the oxidation state).
Kind regards.

Answer:
I don't understand the question
Explanation:
what is your name
Sound waves need to travel through a medium such as a solid, liquid, or gas. The sound waves move through each of these mediums by vibrating the molecules in the matter. If you need more explained ust ask and I an give it more detailed :)
