What is the chemical formula of a paperclip?

Answer 1

You need to be MUCH more specific about 'glue' - that covers dozens of different products !

Answer 2

This is dependant on which material was used to manufacture it,

The question should relate to the material not the finished product.

Answer 3

The chemical formula of a paperclip is typically not applicable since paperclips are made of metal, usually steel, which is a combination of iron and carbon.
