If a substance in a mixture is preponderant--, if the amount far exceeds the amounts of the other substances in the mixture it is usually called an impure substance.

No, not all impure substances look like mixtures. Impure substances can be in the form of solutions, alloys, or compounds in which the impurities are evenly distributed and not visually distinguishable from the pure form.
Bromine is a pure substance. It is an element found on the periodic table with the chemical symbol Br. As a diatomic molecule (Br₂) in its liquid form, bromine consists entirely of bromine atoms and does not contain any other elements or compounds, making it a pure substance.
Dissolved sugar is a homogeneous mixture. While sugar is a pure substance in its solid form, when dissolved in water it forms a mixture where the sugar molecules are evenly distributed throughout the solvent.
Pure substance; it is one form of pure carbon.
No, graphite is a pure substance. It is a form of the pure element carbon.
No, not all impure substances look like mixtures. Impure substances can be in the form of solutions, alloys, or compounds in which the impurities are evenly distributed and not visually distinguishable from the pure form.
Pure substance; it is one form of pure carbon.
This is a homogeneous solution.
No, bromine is a pure substance. It is a chemical element with the symbol Br and atomic number 35. It is a halogen and exists as a diatomic molecule in its elemental form.
No, a solvent is a single substance that is used to dissolve other substances, such as solutes, to form a solution. It is not a mixture but rather a pure substance.
Neither. Oxygen is an element, which is a pure substance and not a mixture.
It is a mixture of potassium salt [K+ and ?-] with an impure form of potassium carbonate. So it is a non-silicate, as it contains no silica.
rubbery substance .
Dissolved sugar is a homogeneous mixture. While sugar is a pure substance in its solid form, when dissolved in water it forms a mixture where the sugar molecules are evenly distributed throughout the solvent.
is a substance that does not dissolve in a solvent form is a mixture called suspension .suspension is a heterogeneous mixture that is opposite to homogeneous mixture

No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
