Not sure how to complete this chemical reaction:
Li + Fe(NO3)3 --->

Frankly, I don't think it will go but I think the spirit of the question is
3Li + Fe(NO3)3 ==> 3LiNO3 + Fe

The reason I don't think this will happen is that if we do it as solids, like this
3Li(s) + Fe(NO3)3(s) ==> no reaction because the solids will not react.

If you put them in solution, the
3Li(s) + Fe(NO3)3(aq) ==>
The Li reacts with H2O before it reacts with the Fe(NO3)3
I think the author of the problem just didn't think through the equation. But I suspect the lesson is for the activity series and as such Li is above Fe and it will replace Fe^3+

Ok thank you. Yes i wasn't sure which way to do it. I was thinking of following the activity series

But in the question it says Li is a solid and Fe(NO3)3 is aqueous
Answered by DrBob222
If your question says Li is a solid and the ferric nitrate is a solid (which isn't in the initial post) then I would write no reaction because the two solids will not react. It was I that wrote in the (s) and (aq). However, in the case that it is in your problem as
Li(s) + Fe(NO3)3 --> then I would write the rxn between Li and water.
2Li + 2H2O ==> 2LiOH + H2

I am not understanding what you are saying? So what would be the answer? Li is a solid and Fe(NO3)3 is aqueous
