Concentrated Acids
The acid will burn a hole through the material.
I think it is a chemical change, as burning is a chemical change.
There is no such thing as "stomatic particles". The root word "stoma" means hole, so by extrapolation there can be no such thing as a 'solid hole' - unless we're talking about doughnuts.
A chemical bolt is when a hole is drilled into a surface, and then filled with some form of resin/concrete, and a bolt is then inserted. When the resin cures this results in an incredibly strong (when installed correctly) mounting/fixing point.

It depends largely on the acid you spilled on yourself. Mild acids like citric acid would just irritate your skin a little, at the worst. On the other side of the spectrum, a carbonic superacid would eat a hole right through your hand.
the big fat but hole
The chemical which manly caused the ozone hole is Chlorofluorocarbons. These are compounds made of chlorine and fluorine which deplete ozone in large amounts.

its a a chemical reaction because you can 't get it back in a hole banana
CFC's caused hole in ozone. They react with ozone and deplete it.
