No. The composition of a homogeneous mixture, called a solution, can vary.
Yes, it is possible.
yes
Yes.
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.
no
Pure substance: matter w/properties/composition that don't vary from sample to sample. (salt, water,etc). Homogeneous mixture: composition can vary; an example is a solution (coffee w/sugar) and is uniform throughout.

A juice is not a homogeneous mixture.
no
Yes, it is heterogenous mixture because the composition can vary throughout it.
Based on the distribution of their components, mixtures can be classified as heterogeneous mixtures or as homogenous mixtures.

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 mixture
Yes, Mixtures can vary but the composition of a compound cannot
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.
A compound is similar to a homogeneous mixture in that the proportions of the atoms throughout the compound/mixture are always fixed and do not vary. For example, a sample of pure C02 gas is a compound and will always have two parts oxygen to every carbon atom. Likewise, a homogeneous mixture of salt water will always have a fixed proportion of salt ions to water. (However, a heterogeneous mixture, such as muddy water would not always have a fixed proportion of mud to water since the mud might settle towards the bottom. The solution strength of a heterogeneous mixture can vary while a homogeneous mixture remains constant).A homogeneous mixture can be separated into its constituent components by physical means. For example, you can evaporate off the water off a sugar-water mixture, or you can filter a mixture of water and sand.A compound, however, requires some kind of chemical reaction to separate it into its constituent elements.
