Quartz is a homogeneous substance. It is the compound silicon dioxide, SiO2.
Granite is a heterogeneous mixture because it is made up of different minerals such as quartz, feldspar, and mica that are unevenly distributed throughout the rock.
Granite is a heterogeneous mixture. This means that it is made of different substances that remain physically separate.
Lemonade is not a mixture but a solution, as it is a homogeneous mixture of water, sugar, and lemon juice. Quartz, granite, and feldspar are all mixtures, as they are composed of a variety of minerals and compounds.
Granite is neither, it is a mixture. You can see grains of different minerals in it.
Pure quartz (SiO2) is chemically homogeneous.

Granite is a heterogeneous mixture because it is made up of different minerals such as quartz, feldspar, and mica that are unevenly distributed throughout the rock.
Granite is a mixture. It is composed of various minerals such as quartz, feldspar, and mica that are physically combined but do not form a homogeneous solution.
Granite is a heterogeneous mixture. This means that it is made of different substances that remain physically separate.
Pure quartz is homogeneous. However, so-called quartz rocks found in nature are usually heterogeneous.
Homogeneous mixtures have uniform composition and properties throughout and are known as solutions. For e.g, when sugar/salt is dissolved in water it forms a solution in which the sugar/salt and water are uniformly mixed (the sugar is dissolved uniformly in water). e.g.airHeterogenous mixtures are those which aren't uniform in composition and properties throughout e.g. granite which consists of quartz, feldspar and mica and you can identify each of the substances sepaately in the mixture. Heterogeneous mixtures can be suspensions or colloids.NOTE: None of these mixtures are compounds.Homogeneous mixtures contain a single phase, whereas heterogeneous mixtures have many phases. ~IHATEe2020~
Chalk is a heterogeneous substance because it is composed of various materials such as calcium carbonate, quartz, clay, and other minerals. These materials are not uniformly distributed throughout the chalk, resulting in a non-uniform composition.
A mixture of sand and water would be a heterogeneous mixture because the sand doesn't dissolve within the waterHeterogeneous.See the Related Questions to the left for more information.
It's obvious from a cursory visual inspection that it's hetereogeneous. Anything with swirls, or specks, or any pattern other than a solid color is hetereogeneous (the reverse is not necessarily true; being a solid color does not always mean that it's homogeneous).
Quartz is a compound. There are many different types of quartz, each containing different materials.
Theoretically yes, though any given sample of quartz may contain inclusions (non-quartz stuff trapped inside) making it heterogeneous.
A granite countertop is a heterogeneous mixture. Granite, the main material in a granite countertop, is a type of metamorphic rock that contains minerals such as quartz and feldspar. Quartz and feldspar are two different types of minerals which make up granite. Therefore, because there are two different types of minerals in one substance it makes it heterogeneous.
