Pure substances have uniform distribution of particles and can be either an element or compound. Mixtures can be separated easily and are not chemically bonded. They do not have uniform distribution.
pure substance?
No, the difference between a pure substance and a mixture is not always easy to observe. While pure substances have definite chemical compositions and properties, mixtures consist of two or more substances physically combined. Some mixtures can be challenging to distinguish from pure substances based on visual observations alone.
Chemists prefer the expression pure substance.
No, it is a mixture; rarely a drug is a pure substance.

The difference between a homogeneous mixture and a pure substance is that a pure substance has a fixed composition and cannot be separated because it is chemically bonded and a homogeneous mixture can be separated.
No.
A pure substance has only one kind of atom or molecule.A mixture has a number of different pure substances mixed together.

A mixture has different properties throughout; a pure substance has the same properties throughout.
A mixture is a substance composed of two or more components physically combined. An element is a pure substance composed of one kind of atom. A compound is a pure substance formed when atoms of two or more elements chemically combine.

A pure substance is a substance that has only that substance in it. One kind of molecule or atom. A homogenous mixture can have different molecules and/or atoms in it, but they have to be in the same physical state. Water mixed with honey would be a homogenous mixture, because they are both liquids. Water mixed with sand would be heterogeneous.
No a mixture is by definition not a pure substance.
