In an homogeneous mixture phases are not distinct; in an heterogeneous mixture the situation is inverse.
In an homogeneous mixture phases are not distinct; in an heterogeneous mixture the situation is inverse.
A heterogeneous mixture has two or more distinct phases with different characteristics. Because of this, two random samples of a heterogeneous mixture may have different compositions. For example, the phases in mud are the water and soil particles, which remain distinct from one another. These phases are not necessarily visible, but may exist as microscopic clusters or particles. By contrast in a homogeneous mixture any two random samples will be identical.
Actually, the main difference is in their uniformity. Homogeneous mixtures have uniform composition throughout, while heterogeneous mixtures have distinct phases with visible boundaries. Chemical bonds are not a defining factor for distinguishing between these types of mixtures.
I suppose that ketchup must be considered nonhomogeneous because frequently two phases are distinct.
No, pyrite is not a heterogeneous mixture; it is a mineral composed of iron and sulfur, with the chemical formula FeS₂. Pyrite is classified as a solid compound and has a uniform structure throughout its crystalline form. In contrast, a heterogeneous mixture consists of different substances that can be physically separated and have distinct phases, such as sand mixed with gravel.
To make salt water a heterogeneous mixture, you could add an immiscible substance such as oil or sand to the water with salt. This would create two distinct phases that do not mix evenly, resulting in a heterogeneous mixture.
When two substances form a mixture, they must retain their individual properties and identities, meaning they do not undergo a chemical change. The components can be present in varying proportions and can typically be separated by physical means, such as filtration or distillation. Additionally, the mixture can be homogeneous (uniform composition) or heterogeneous (distinct layers or phases).
A heterogeneous mixture with one substance present and two phases present is a suspension. In a suspension, the particles of one substance are physically mixed in another substance but are not dissolved, resulting in two separate phases. Examples include sand in water or oil in water.
A heterogeneous equilibrium refers to a chemical equilibrium in a system that contains multiple phases, such as a solid, liquid, and gas phase. In these systems, the concentrations of reactants and products in each phase are related according to the equilibrium constant.
Because they can form when all components are mixed on the level of their molecules/ ions, or when there are regions containing only one particle or the other.
The system formed by the addition of sulfur to carbon disulfide is considered heterogeneous because sulfur and carbon disulfide are two distinct phases that do not mix uniformly.
