Molecular Formula of Sand

The molecular formula of sand
There are strange questions in the world, and I want to know the molecular formula of sand. Sand is often found between heaven and earth, on the banks of rivers and lakes, in the wilderness by the road, everywhere.

The main component of sand is silicon dioxide, whose molecular formula is $SiO_2 $. Silicon, ranked fourteenth in the periodic table of elements, has unique properties. Oxygen depends on life and plays an extraordinary role in the synthesis of all things. The combination of the two forms this silicon dioxide, which forms the main body of sand.

Silicon atoms and oxygen atoms are covalently bonded, and each silicon atom is combined with tetraoxygen atoms to form a stable tetrahedral structure. Many of these tetrahedrons are connected to each other to build the microscopic structure of sand.

Natural sand is also not pure silica, and often contains other substances. Such as trace amounts of metal oxides, iron, aluminum, calcium, etc., or organic impurities. Although this impurity is small, it may affect the color and texture of the sand. The color of yellow sand may be due to its iron content; the purity of white sand, or the purity of few impurities.

The molecular formula of sand inspection shows its chemical composition and can be used in many fields of industry and scientific research. In construction, high-quality sand is a good concrete material, which is relied on for strong buildings; in glass manufacturing, sand is the basic raw material, and transparent glass is born from it.

The molecular formula of sand exploration is actually the mystery of exploring natural substances, knowing their properties and uses, so as to facilitate people's actions in the world.
