1. Zn  +  CuCl2
2. Au  +  CuCl2
3. Na  +  KCl
4. Zn  +  MgCl2
5. Ag  +  CuCl2
6. Fe +  KCl
7. Pt  +  AgCl
8. Sn  +  CuCl2
9. Al +  CuI2

Now, I'm not just looking for answers (though that would be nice lol), I'm trying to understand how to determine which formulas would create a spontaneous reaction.

Thing is, due to my aforementioned (in my first thread) lack of Grade 11/12 science/chemistry, I have no clue what I'm looking at whatsoever.

I mean, I can tell that obviously Zn is Zinc, Fe is Iron, etc....but other than that, I'm drawing a blank.

It is about reactivity series (google if you have no idea).

Alrighty, so I found that. Thing is, it doesn't show anything regarding Chlorine on the table at the top. May have to google that to find a better table.

I'm still confused though, but I'm gonna keep reading.

Chlorine doesn't change. Actually it is not chlorine - these are chloride ions. They will just float in the solution.

Alright, so I've got the table. How do I determine what kind of reaction is spontaneous, so I can then figure out which formula will not cause a reaction?

It's written on the page you linked to: http://en.wikipedia.org/wiki/Reactivity_series#Single_displacement_reactions

Also look up single displacement reactions.

So single displacement reactions = spontaneous, and anything else = non spontaneous?

Is that what it says in the article?

Uhhh...yes? I see something about "thermite reaction" which even with my grade 10 science skills, I believe is a spontaneous reaction....correct me if I'm wrong.

Uhhh...yes?

Can you quote the text that actually says that all single displacement reactions are spontaneous?

Did you look up single displacement reactions for further reading?

Hmm...I don't think I can. I'm going to have to look up YouTube videos on this subject.

YouTube was no help, constantly pointing me towards the Gibbs Free Energy equation.

Can someone just come out of the woodworks and tell me how to find out which formulas are spontaneous or non so I can finally move onto the next chapter of this coursework?

You can't predict the spontaneity without Gibbs Free Energy, just like you can't dig a hole in the ground just by staring at a spade.

Well s#*$. How do I find the needed values for the equation, i.e. what the hell is "Delta" and how do you calculate it. How do I get the temperature value and the enthalpy and entropy values? For example Zinc. I've looked on the Wikipedia article of Zinc and I see two or three different temperature values, and nothing about enthalpy and entropy.

I am entirely confused.

There are usually tables with standard Gibbs energies. Alternatively, since these are oxidation/reduction reactions, you can use standard oxidation and reduction potentials, which are widely available.  Using the Nernst equation you can easily convert these to Gibbs energies.
