Chemical Property
Density is an intrinsic property, not an extensive property of matter. This is because it DOES NOT depend on the size of the sample (amount). The density of a small piece of matter is the same as the density of a larger piece of that same matter.
No, a piece of carpet is not a pure substance. It is typically composed of a variety of different materials such as fibers, backing, and possibly dyes.
Spreading butter on toast is a physical change because the butter changes its shape and distribution on the toast but does not undergo a chemical reaction. The butter still retains its chemical composition and can be easily reversed by heating or cooling.
Crushing a piece of chalk breaks it down into smaller particles, typically creating a powdery substance.
Because you can't put it back together. Imagine burning a piece of paper, there is no way that you can get that piece of paper back. Burning that piece of paper was a chemical change because you changed the chemical properties of the paper. Crumpling or cutting the paper doesn't change the molecular structure of the paper, so it is a physical change.

A physical property is something like color, size, and state. The substance still stays the same! A chemical property is a change in substance. Burning is a chemical property because if you burn a piece of wood, it is a new substance and you cant change it back to regular wood. It is usually very hard to change a chemical change BACK to its original substance. The answer to this is No
Yes, because if it doesn't change whatever the substance is, it's a physical property. For example, if you have a piece of paper, you can fold it in half. When you do that, it proves the piece of paper to be flexible without turning the paper into something else.

This looks to me like a confusion with "chromatography". Say you put some liquid substance on a piece of paper. Some molecules will move (diffuse) faster than others; thus, the substance becomes separated.
Any chemical reaction produce a new substance.

Poccession of a controlled substance means you were either searched or a piece of property you own was searched and they found narcotics IE: Meth, Crack, Heroin Or Other Drugs.
The candle burning is a chemical process.
In a physical change, the substance is still the same substance after the change. But in a chemical change, the substance became another substance with different properties from the original substance.Physical change is changing the appearance of something. Example - Rip a piece of paper - physical change. Burn gasoline - chemical change.
I would describe it as a million different piece of a picture that becomes more and more allusive the more in depth you get.
A written claim to some piece of property
