Concentrated Acids
A cylinder in a dry cleaning machine is a rotating drum where clothes are placed for cleaning. The cylinder typically contains a solvent or chemical solution that helps remove stains and dirt from the clothes during the cleaning process. It rotates to agitate the clothes and facilitate the cleaning action.
The process of acid burning a hole in clothing is a chemical change. This is because the acid reacts with the fabric, breaking down its chemical structure and forming new substances, ultimately leading to the formation of a hole.
Atoms are the smallest particles involved in chemical bonding. Atoms bond together by sharing or transferring electrons to form molecules or compounds. Ionic, covalent, and metallic bonds are three types of chemical bonds that atoms can form.
It is highly unlikely that you can make a hole in a sixpence with a soldering iron due to the hardness of the metal. Sixpences are typically made of a durable metal alloy that would not easily melt or create a hole with a soldering iron. It would be more practical to use a drill or specialized tools for this purpose.
Battery acid can cause permanent damage to clothes by staining or discoloring the fabric. It can also weaken the fibers in the fabric, leading to holes or tears. It is important to quickly remove any battery acid from clothes by rinsing with water and then washing with a stain remover.

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 chemical which manly caused the ozone hole is Chlorofluorocarbons. These are compounds made of chlorine and fluorine which deplete ozone in large amounts.

Hole punching paper is a physical change. It involves altering the shape or form of the paper without changing its chemical composition.
CFC's caused hole in ozone. They react with ozone and deplete it.
