It is Homogeneous
Solid silicon dioxide is not considered a compound or homogeneous mixture. It is considered a heterogeneous mixture because it contains traces of visible components that can be separated physically.
Silicon is an element, not a mixture. It is a solid metalloid that is commonly found in nature in its pure form.
Air pollutants can be both homogeneous and heterogeneous. Homogeneous pollutants are evenly distributed in the air, such as carbon dioxide. Heterogeneous pollutants are not evenly distributed and can vary based on location, such as particulate matter near an industrial area.
is silicon a mixture? Silicon is a pure substance because it is an element.
Sand with shells is a heterogeneous mixture because it contains different components (sand and shells) that are visibly different and can be separated easily. In a homogeneous mixture, the components are evenly distributed and not easily distinguishable.
Quartz is a homogeneous substance. It is the compound silicon dioxide, SiO2.
