The surface of the copper on the pennies are most likely cleaned, because vinegar is too weak of an acid to do anything else. If you were to put a scratched penny into hydrochloric acid would be a different story. The inside zinc of a post 1982 penny would react with the chlorine in the hydrochloric acid and change to an aqueous state, leaving behind the copper plating.
So if you want an answer based on vinegar : nothing besides the penny getting its surface cleaned.
No, vinegar is a too diluted (5-10%) and weak acid (Ka=0.00002), it will only dissolve carbonate- and some oxide- surface corrosion.
The green copper(II) acetate is formed.
It will turn green.
You can also turn pennies and some other coins green by letting them sit overnight in a paper towel soaked in vinegar. and if you want to clan pennies to shine, put them in a cup of vinegar and salt dissolved. (I once tried cleaning them with a pinch of kosher salt instead and it dug a hole through the penny! -NOT RECOMENDED!!!)
Iodine will color black-blue only with 'hydrated' swollen carbohydrate body within the soaked seed.
It evaporate. Or flows into large bodies of water.
mud
Soaked and damp.
They are copper and if soaked in vinegar the tarnish will come off and they will shine again.
Because the chemicals in a penny react with the vinegar

Not much, but if you soak it in vinegar the shell will dissolve!
The eggs won't react, it is the vinegar that acts on the egg. The acid in the vinegar will corrode the calcium in the egg shell, causing the egg to become soft, like rubber.
Foods soaked in vinegar are pickled, and soaked in salt are salt-cured. Both are means of preserving food. <><><> It is called "pickling"
They are not bendable unless soaked in vinegar.

Because when it is soaked in vinegar,the shell is making direct contact with the vinegar;the shell is made from carbonate and will be dissolved by the acid in the vinegar, whereas, the membrane is protein so it takes a lot longer to be affected by the vinegar. The reaction is different so the membrane appears not to be affected.
If you put the egg in vinegar then put it into Gatorade then the egg looks defalated, red, and very sticky.
yes it will because of the acids in the vinegar
