Air is a mixture as it contains more than one substance!
SiO2 would be Silcon oxide and as it contains atoms of both Silicon and Oxygen it can't be an element. It is a compound.
It's elemental Iodine. Iodine exists in nature has a diatomic molecule.
Pure iodine, or diatomic iodine. It rarely exists like that though, because it's so very reactive. It's nearly always tied up in a compound.
Iodine is a chemical element; the molecule is diatomic.
It is a compound with formula SiO2
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.
Blad is a compound u know, u's lot r retards and r so dum f****** hell.
Silicon dioxide (SiO2) is a compound because it is composed of two elements (Si and O) that are chemically combined.
the chemical formula for sand is SiO2, so it is a compound, made from Silicon and Oxygen
It is a compound with formula SiO2
SiO2 is not an element, it is the compound silicon dioxide.
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.

One example is oxygen. Oxygen combines with silicon to form silicon dioxide, SiO2.
Silicon dioxide (SiO2) is a compound.
Auto exhaust= CO2+CO+SIO2+H20. Auto exhuast is a mixture
Silicon dioxide contain 46,743 49 % silicon and 53,256 51 % oxygen.
One atom that can form a bond with silicon is oxygen, to form silicon dioxide, SiO2.
NO!!! Silicon is constituent element of sand. Sand is the compound. Sand has the formula 'SiO2'. (Silicon dioxide).
