Hi I have some redox reactions that I do not know how to do.

1- 2 PbS + 3 O2 ----> 2 SO2 + 2 PbO

2- 2 H2 + O2 -----> 2 H2O

And I have one question, for H2 is it's charge +2 (because of the 2 , so 2*1) or +1?

Yes, one Hydrogen ion (actually one proton) has charge +1 and so two have charge +2.

That's good because that way "2 H2" has charge +4 while an Oxygen ion has charge -2 so that O2 has charge -4. - Jul 3rd 2013, 05:17 PMsakonpure6Re: Redox Reactions
can you please help me solve those two questions?

I guess then, the question is, what do you

**mean**by "solve them"? Show that they are valid? Start by showing that there are the same number of atoms of each element on the two sides. - Jul 3rd 2013, 09:17 PMShadowKnight8702Re: Redox Reactions
I assume by "solve", you mean find the net ionic equations. My suggestion for that would be the half-reaction method.

This podcast that I used in school tells everything you need to know about redox reactions: https://docs.google.com/file/d/0Bw9U...ZvTmF0Mlk/edit

Happy Studying.
