Homework Help: Chemistry

Posted by Alyson on Sunday, May 15, 2011 at 9:26pm.

I need to explain which species is oxidized and reduced, what the reducing agent and oxidizing is, and explain why for each of the following equations. One of them is not a reduction-oxidization problem and I need to explain why.

1. 2Na + Cl2 --> 2NaCl
2. Pb(NO3)2 + 2NaCl --> PbCl2 + 2NaNO3
3. 2PbS + 3O2 --> 2SO2

Thank you so much!!
