Silicon dioxide is a compound.
Sand is a mixture of silicon dioxide and small amounts of other minerals, but silicon dioxide itself is a compound made of silicon and oxygen atoms. Carbon dioxide, on the other hand, is a separate compound made of carbon and oxygen atoms.
Silicon dioxide is a compound, not an atom, element, or mixture. It is composed of silicon and oxygen atoms bonded together in a specific ratio to form a single chemical substance.
Silicon oxide is a compound, not a mixture. It consists of silicon and oxygen atoms bonded together in a specific ratio, usually in the form of SiO2, known as silica.
Obsidian is a naturally occurring volcanic glass composed primarily of silicon dioxide, which is a compound made up of the elements silicon and oxygen. Therefore, obsidian is not an element but a mixture of elements in compound form.
Silicon dioxide (SiO2), also known as silica, is a common compound that contains silicon. It is found in sand, quartz, and glass.

Silicon dioxide is a compound, not an atom, element, or mixture. It is composed of silicon and oxygen atoms bonded together in a specific ratio to form a single chemical substance.
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 oxide is a compound, not a mixture. It consists of silicon and oxygen atoms bonded together in a specific ratio, usually in the form of SiO2, known as silica.
Silicon dioxide is a homogeneous mixture, as it is a compound composed of silicon and oxygen atoms uniformly distributed throughout the material.
Silicon dioxide is a pure substance. It is a chemical compound made up of silicon and oxygen atoms in a fixed ratio, with a specific chemical formula (SiO2).
Obsidian is a naturally occurring volcanic glass composed primarily of silicon dioxide, which is a compound made up of the elements silicon and oxygen. Therefore, obsidian is not an element but a mixture of elements in compound form.
Silicon dioxide is a compound. It is composed of silicon and oxygen atoms bonded together in a chemical structure.
Silicon dioxide is the main component of sand, but it is not the only compound present. Sand may also contain other minerals like quartz, feldspar, and mica, as well as traces of other substances depending on the source of the sand.
