Sand consist of Silicon dioxide (SiO2)
Sand is silicon dioxide. Note that as sand is generally coloured the silicon dioxide contains traces of metal oxides, typically iron.
No, silicon dioxide is a molecule.
silicon (IV) oxide or silicon dioxide has giant covalent structure

Sand consist of Silicon dioxide (SiO2)
No, silicon dioxide forms a network covalent structure, and so doesn't dissolve in anything:
Sand is silicon dioxide. Note that as sand is generally coloured the silicon dioxide contains traces of metal oxides, typically iron.
No, silicon dioxide is a molecule.
Silicon dioxide is a compound.
Silicon and oxygen, in this form. SiO2 Silicon dioxide.
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.
silicon dioxide is reactive when eating egg
