No, a typical soil sample is heterogeneous.
A homogenous mixture means that all components of the mixture are equally distributed throughout the entire mixture. Soil, then, would not be a homogenous mixture. Every time one takes a sample of a soil mixture and analyzed it, it would have a different make-up then other samples taken from the soil mixture. One would seldom be able to get two samples that had the same make-up.
No, soil is heterogeneous.
No. A mixed sample, by Nature, is heterogenous and so may not also be a homogenous (pure) substance.
No. Soil is a heterogeneous mixture.

In a heterogeneous mixture, the components do not have a uniform composition throughout the sample. For example, the bubbles in soda, or champagne in this situation, are heterogeneous mixtures.

No, a typical soil sample is heterogeneous.
A solution is a true homogeneous mixture: only one phase.
table vinegar is dilute acetic acid and is a homogeneous solution

Homogeneous Mixtures = of one or more substances (the solutes) dissolved in another substance (the solvent). Heterogeneous Mixture = mixtures with inconsistent, non-uniform composition. The parts of a heterogeneous composition can be mechanically separated from each other.
The symbol N2 is for the diatomic molecule of nitrogen; it is not a mixture.

One way to decide whether a sample of matter is homogeneous or heterogeneous is just by looking at it.
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.
Water (H2O) is a chemical compound.
