your mixing two chemicals together so of course its a chemical change
is mixed with Ca-Bentonite, Flake Graphite Powder, Sodium Carbonate, Coal Powder & Carbon Powder
Rusting is a chemical process when the surface of a metal becomes attacked by elements in air or water and it asorbs oxygen (or sometimes sulfur) to become a compound of it. However, many materials do not rust, because the modified surface so formed does not peel or flake-off, exposing more of it for this chemistry to repeat its action.Thus rusting is a very chemical change (as peeling of the surface is not really defined as a physical change).
The paint began to flake off.In Britain, Flake is a kind of chocolate bar.She choked on a chocolate flake in her mocha.
I can give you several sentences.The snow flake melted instantly.I found a flake of obsidian on the ground.That rock will flake easily when struck.You could also use the slang meaning of someone who is eccentric or odd. "That fellow is a real flake!"
ParaDichloroBenzene available in both forms. Crystal & flake form. For more details email : venusimpex@yahoo.com

In nature, graphite is found as flake, vein, or amorphous form. Graphite is polymorph of carbon. Graphite is a non-metal that is a conductor of electricity.
Graphite's atomsare arranges in layers, like shest of hexagonal tiles and wave weak bonds.
Graphite appears naturally in three forms: amorphous, which is the last stage of the coalification process; crystalline flake, which is used in brake linings and pencils; and lump, used mostly in batteries

Physical change: bending. Chemical change: Rusting (oxidation). An example of both in one item: A wrought iron fence was heated and bent into a decorative pattern. After 20 years, the fence shows evidence of deep rusting, especially on decorative curves.
