Think about your question you literally just asked. If the person is a non-English speaker than from where they come from it may mean something totally different to them than it does to us. It could also demonstrate a totally different way of saying the word as well.
Answer:
C
Explanation:
I believe the answer is C.
To write a balanced chemical equation for the given redox reaction, we need to know the half reactions of the substances involved. Redox reaction means oxidation-reduction reaction. Oxidation is when one loses electrons making it more positive while reduction is gaining electrons which makes it more negative. Iron here is being oxidized and will have the half reaction:
<span>Fe2+(aq) ---> Fe3+(aq) + e+
</span>
<span> S2O2−6 is being reduced in the process and will have a half reaction of:
</span>S2O2-6 + 4H+ + 2e- ----> <span>2H2SO3
</span>
Adding the two half reactions would yield to the balanced chemical equation. We do as follows:
2 (Fe2+ ---> Fe3+ + e+)
S2O2-6 + 4H+ + 2e- ----> 2H2SO3
----------------------------------------------------------------
2Fe2+ + S2O2-6 + 4H+ ----> 2Fe3+ + 2H2SO3 ( balanced oxidation - reduction reaction )
