A mixture contain two or more types of molecules.
A compound implies some chemical bonding at the atomic or molecular level. A mixture suggests that although the components may be in intimate contact, no chemical bonding has taken place.
By definition, a homogeneous mixture is a substance that is uniform at the molecular level. An example of this is salt water.
A solution is a type of mixture at the molecular/atomic level. Mixtures that are not solutions usually contain particles visible at either the microscopic or macroscopic level.

Homogeneous mixture.
A Penny is not a compound. It's just one word.
sand is a heterogeneous mixture of different grains of different types of stone. An ionic bond is a bond that happens at a molecular level (atoms bonding with atoms), and sand is just many small rocs and crystals mixed together
Solution: A mixture that appears to have the same composition, color, density, and taste, and is mixed at the atomic or molecular level.
no they are not
An element is a pure substance A compound is two or more pure substances joined together chemically, such that they can not be separated physically - a new substance. A mixture is two or more substances that are mixed up but not joined together, such that they can be separated physically. There is also the a "solution" which is like a mixture but where the mixing is happening at a molecular level, it is possible to separate the components physically, but not easily.
yes Everything is matter at the molecular level. Concrete is a mixture of sand, gravel and water.
The composition of air is practically the same at the level of earth.
