In addition, a chemical reaction requires a very elevated or very low PH level in order to create this alkaline or acidic condition.
No, chemical reactions can take place at literally any pH. Try again.
There claim comes from the "in order to create this alkaline or acidic condition" part. Yes, chemical reactions can occur at any pH, however, by definition, alkaline means high pH and acidic means low pH. So, yes, in order for the given conditions, the pH must be very high or very low.
As far as this comment:
See, um, I'm no physicist, but I do know that in a galvanic cell, the metals most definitely do NOT touch each other. There is no metal-to-metal contact. None. The metal electrodes only interact through an electrolytic medium which carries ions between the two of them.
The metals do touch each other, it just so happens that one of the metals is in solution, part of the liquid. In order for the transferance of IONs in a galvanization reaction (aka an oxidation-reduction reaction), the metals must touch. Either the oxidizing or reducing agent, in the aqueous solution that comprises a galvanization reaction for batteries and the like, must be aqueous itself, part of the solution that the other metal is submersed in.
So far, two for two.
Last one: A chemical reaction requires hours if not days to manifest.
Try telling that to someone who works with high explosives. Or, if you don't believe me, go to your kitchen and add some vinegar to some baking soda. It won't take hours to react, but see for yourself if you're unsure.
Chemical reactions *can* take hours or days to manifest, if not for catalysts. Example, the decompisition of elements is a chemical reaction and could take up to years or even centuries for it to reach it's half-life, and that is, by definition, only when half of it has decomposed.
All sounds fair.
