That is the definition of a catalyst.
A is a catalyst. Catalysts can speed up chemical reactions by providing an alternative pathway with lower activation energy, but they themselves are not consumed in the reaction.
A physical property, such as color, shape, density, or temperature, can be observed without changing the identity of matter. These properties describe the characteristics of a substance and can be measured or observed without altering the substance itself.
A substance that speeds the changing of food into a usable form* is called an enzyme. More generally, in any chemical context, a substance that speeds a reaction without itself being changed is called a catalyst._______________________________________*This changing of food into a usable form is called "digestion".
An oxidizing agent is something that removes one or more electrons from something itself (the oxidizing agent itself gains one or more electrons).A reducing agent is something that gives electrons to something else (the reducing agent itself looses electrons).A catalyst is something that speeds up a reaction although the catalyst is not consumed itself in the reaction. The catalyst does this by lowering the activation energy of the reaction.See the Related Questions to the left for more information about oxidation and reduction reactions and catalysts.

Physical weathering is the breaking down of something which does not change a substance's composition itself
mass, volume, shape because without those three it would be nothing
Nothing. Oxygen itself is not flammable. Fire is a reaction between a flammable substance and oxygen.
No one knows this is a question that someone may know but chances of that happening are slim to nil :)
Well if u cut a piece nothing will happen because it is by itself if u cut it with a blade with another substance like hydrochloric acid than a reaction will happen( lights up ) but I there is no other substances mixing with it that nothing will happen

you do excatly that, let it happen by itself...don't do anything?
