Hi, I understand that these are probably easy questions, but I have attempted them and do not understand how to work them out. Any help will be great, thanks

In the equation below, which atoms are being oxidised and reduced?
4FeS
(s) + 11O
2(g) ![right arrow :rarrow:](https://www.chemicalforums.com/Smileys/classic/rarrow.png)
2Fe
2O
3(s)+8SO
2(g)I attempted it and got 2 atoms being oxidised and that cannot be right.
![Huh ???](https://www.chemicalforums.com/Smileys/classic/huh.gif)
What is the oxidation and reduction half equation for:
4FeS
2(s)+14O
2(g)+4H
2O
(l) ![right arrow :rarrow:](https://www.chemicalforums.com/Smileys/classic/rarrow.png)
4Fe
4+(aq)+8SO
42-(aq)+8H
+(aq)I'm unsure about how to write the oxidation half equation.
thanks
