Silicon and oxygen..
When SiO2 reacts with H2O, it forms silicic acid (H4SiO4). The reaction results in the dissolution of SiO2 in water, leading to the formation of the acidic solution.
SiO2 is the chemical formula (not symbol) of silicon dioxide.
Si02 is the chemical formula for silicon (Si) dioxide. It is major component to consumer and automotive glass, and used by the high tech industries for fabricating fiber optic cables.
SiO2 is a covalent compound. It is made up of silicon and oxygen atoms that share electrons to form covalent bonds within the molecule.
Quartz is the mineral that is composed of silicon dioxide (SiO2). It is a abundant mineral found in various types of rocks and geological settings.
The answer that follows is good enough for personal knowledge or school students. Anyone higher than this should do read the Mantle page on wikipedia. Reference : NET The main element is oxygen. The main compound is silicon dioxide. (Si02)
SiO2 stands for silicon dioxide, which is a chemical compound composed of silicon and oxygen. It is one of the most common and abundant materials on Earth, found in various forms such as quartz, sand, and glass. Silicon dioxide has many industrial applications, including in the manufacturing of glass, ceramics, and electronics.
No. It is quite difficult for elements to change into new elements.
There are a total of 118 elements known to exist on the periodic table.
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.
