A compound is a molecule that fits this description. Water is such a compound and is a good example.
It is called a compound.
A Compound
no homogeneous substances is not uniform as it contains mixture of many substances and therefore all particles cannot remain in fixed ratio.
it is a mixture.
I believe the answer is homogeneous. A Homogeneous mixture is something that is uniform throughout.
Some, it depends on the compound, though for most it is very hard. Excluding water, in which the oxygen and hydrogen can be separated simply running a strong enogh electrical current through it.
Homogeneous
cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
The substances which are all having uniform chemical composition through out are all known as homogeneous substances.
A solution.

A substance is a type of matter with uniform properties, where as a mixture is a type of substance that can be made by mixing a variety of substances together. There are two types of mixtures - homogeneous and heterogeneous.
no homogeneous substances is not uniform as it contains mixture of many substances and therefore all particles cannot remain in fixed ratio.
homogeneous-- looks same throughout heterogeneous- can be separated by hand
"Homogenous" describes substances that are uniform in composition or nature. It means that all parts of the substance are the same or similar throughout.
A mixture is composed of substances that are not chemically combined, and which do not have a definite composition. A homogeneous mixture is uniform throughout. A solution is a homogeneous mixture. A heterogeneous mixture is not uniform throughout. Examples of a heterogeneous mixture are granite or beef stew.
A solution differs from other types of mixtures because one component of a solution can dissolve into another component. A solution will be uniform throughout and does settle into any different compound.
it is a mixture.
Physiography is another term for physical geography. Uniform means the observed things have very similar qualities, so uniform physiography would mean that the observed terrain remains relatively the same throughout.
