Chemistry: Noble metals, big need of fast help

In summary, the conversation is about someone seeking help with a lab report and asking for clarification on questions related to writing equations, the reducing ability of precious metals, and the practical use of knowing the reactivity series of metals and hydrogen. The conversation ends with the person thanking others for their help and asking for clarification on the use of Zn in the reaction.

Hi!
I'm writing a lab report and have some questions that I can't find the answer of... I really hope that someone can help me.

Homework Statement


1. First of... I'm having a small problem with writing an equation for Zn reacting with a HCl solution (only H+ should be in the equation).

2. In genereal, would you say that the so-called precious metals (noble) have high or low recuding ability? Explain your answer

3. What practical use is there in knowing the reactivity series of the metals and of hydrogen?

Homework Equations





The Attempt at a Solution


1. Zn (s) + 2H+ (aq) -> Zn (s) + H'2 (gas) hmm?
2. Haven't found anything...
3. To know what metals that oxidies?... or?... someone that can develope my answer if it's right?


Please, I'm desperate right now... I have to go to sleep soon and need this to be done... many thanks.

I think you mean:
Zn + 2HCl -> ZnCl2 + H2 (g)

or if you prefer as a redox
Zn + 2H+ -> Zn2+ + H2 (g)

thank you, anyone that can clarify the rest?
and should Zn be aq in the reaction?
