cause the molecules in the metal are squeezed tight together
A wire that has been coated with zinc tends to be protected from "galvanic corrosion", meaning that it will be less likely to corrode. The wire could be "hot dip" galvanized or it could be electro-plate galvanized to be considered a galvinized wire.
Fake gold is the type that is most likely to corrode. Real gold does not corrode.
Yes, both HCl and Acetic acid will corrode it .
Gold alloys doesn't corrode in normal conditions.
Water does, so I am pretty sure steam will
No such thing as a galvanized iron roof. They are galvanized steel. The sound is distinct and as I cannot post audio it is impossible to describe the sound. But if you will click the link you can hear it.
If you do connect copper pipe to galvanized pipe, you will need a dielectric coupling or else the galvanized pipe will corrode. Same with connecting galvanized pipe to brass fittings. Brass is an alloy that contains copper and therefore the same electrolytic properties will exist unless a dielectric coupling is used. Hope that helps you out.

I wish to use galvanized screws tru aluminum roof OR Stainless screws tru aluminum roof . Any chemical reaction ?
None must be stripped to do the job correctly

Galvanizing is a process of coating sheet steel with zinc. It makes the steel rust resistant, thereby prolonging it's life. That's why the galvanized roof lasts longer.
Galvanized typically, although stainless steel would be hard to beat.
You might even consider putting a small bit of PVC between them because those 2 metals will each cause the other to corrode.
If it is straight zincalume or galvanized iron there should be no problem however acetone is a solvent so if it is painted you may damage the paint or remove some of it. Acetone seems like a strange choice for cleaning galvanized iron though. Detergent and hard brush would be better and less toxic.
Yes. Use a threaded fitting, male or female as needed on the copper and screw the galvanized into it.You must use a dielectric fitting to connect copper to galvanized pipe. If you don't, a galvanic reaction will occur and the piping will corrode and leak. You can use a Dielectric Union or a Threaded Brass fitting to join the two types of piping together.UNIONS can leak the best answer would have been a dielectric nipple
