Because a mixture means that it contains a mix of substances. And you can choose to mix different amounts (solutions), instead of where in order to create that compound, a specific ratio of elements are required. If the ratio is incorrect, the result will not equal the same compound.
Yes, Mixtures can vary but the composition of a compound cannot
Duct tape is a mixture, not a compound and composition can vary with brand. Therefore, there is no chemical formula.
a mixture
No. The composition of a homogeneous mixture, called a solution, can vary.
Hell yea!

A fixed composition is not a characteristic of a mixture. The composition of a mixture can vary, unlike the composition of a compound that forms a chemical reaction.
A compound has a definite composition, while a mixture's composition can vary.
Compounds are made by combining two elements to an exact percentage, to change one thing would revert it to its original elements. Mixtures are combinations of two elements that do not depend on this as a mixture is not chemically bound. Jay Sanga
A compound is composed of two or more elements chemically combined in a definite proportion. The components of a mixture are not chemically combined and can vary in proportion.
Brass is not a compound, because its atomic composition can vary from one sample to another. Instead brass is a mixture, of the special type called an alloy, because it is a mixture primarily of metals.
Duct tape is a mixture, not a compound and composition can vary with brand. Therefore, there is no chemical formula.

No. The composition of a homogeneous mixture, called a solution, can vary.
be separated by physical means such as centrifuge and filters, etc. example: salad dressing is a mixture cuz you can centrifuge the mixture and all the oil goes to the top, vinegar on bottom. example #2: salt and pepper in same container is a mixture because u can separate each individual crystal by hand (if u have the time and patience to do so :P)
Hell yea!
I am not 100% sure, but i believe variable composition is when the composition of a mixture can vary, or contain different properties, elements/compounds... etc. An example of variable composition would be a heterogeneous mixture, which has no uniform way of being composed. Where as its opposite, a homogeneous mixture, has a set composition of the same properties, elements/compounds... etc. and can be recreated.
