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.
no it is not
No, silicon is an element.
No it is not
sand is a mixture, not a compound.. silicon dioxide is just a compound
is silicon a mixture? Silicon is a pure substance because it is an element.
Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
It is Homogeneous
Heterogeneous
Quartz is a homogeneous substance. It is the compound silicon dioxide, SiO2.
Silicon dioxide is a compound.
Which one is mixture carbon dioxide = compound silicon = element silicon dioxide = compound or sand = mixture so sand is the answer.

Silicon dioxide is a compound of the elements silicon and oxygen. Its chemical formula is SiO2. Impure Silicon dioxide is very common ; it is the sand on a beach.
The purest sand is a compound, silicon dioxide. Most ordinary sand, however would contain some other materials and could be either a homogeneous or a heterogeneous mixture.
