  2. Silicon monoxide - Wikipedia

    en.wikipedia.org/wiki/Silicon_monoxide

    Silicon monoxide is the chemical compound with the formula SiO where silicon is present in the oxidation state +2. In the vapour phase, it is a diatomic molecule. [ 1 ] It has been detected in stellar objects [ 2 ] and has been described as the most common oxide of silicon in the universe.

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

  6. Carbothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Carbothermic_reaction

    The chemical equation for this process when starting with fluoroapatite, a common phosphate mineral, is: 4 Ca 5 (PO 4) 3 F + 18 SiO 2 + 30 C → 3 P 4 + 30 CO + 18 CaSiO 3 + 2 CaF 2. Of historic interest is the Leblanc process. A key step in this process is the reduction of sodium sulfate with coal: [3] Na 2 SO 4 + 2 C → Na 2 S + 2 CO 2

  7. Silicon compounds - Wikipedia

    en.wikipedia.org/wiki/Silicon_compounds

    Silicon compounds are compounds containing the element silicon (Si). As a carbon group element, silicon often forms compounds in the +4 oxidation state, though many unusual compounds have been discovered that differ from expectations based on its valence electrons, including the silicides and some silanes. Metal silicides, silicon halides, and ...

  8. Silicon–oxygen bond - Wikipedia

    en.wikipedia.org/wiki/Silicon–oxygen_bond

    A silicon–oxygen bond (Si−O bond) is a chemical bond between silicon and oxygen atoms that can be found in many inorganic and organic compounds. [1] In a silicon–oxygen bond, electrons are shared unequally between the two atoms , with oxygen taking the larger share due to its greater electronegativity .

  9. Siloxane - Wikipedia

    en.wikipedia.org/wiki/Siloxane

    In organosilicon chemistry, a siloxane is an organic compound containing a functional group of two silicon atoms bound to an oxygen atom: Si−O−Si. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H[OSiH 2 ] n OH and [OSiH 2 ] n . [ 1 ]
