Question 11An organic compound is known to contain only carbon, hydrogen and oxygen. The compound contains, by mass, 39.1% of carbon and 8.7% of hydrogen.The number of carbon atoms in the empirical formula is C A. I B. 2 C. 3 D. 4 ...
Protecting a functional group of an organic compound containing minimally two carbon atoms by reacting with silane compounddoi:US6881855 B2Silanes of the formula R a 1 R 4-a-x SiL x (I) where each R is identical or different and is a monovalent, optionally substituted hydrocarbon radical ...
Using organic polymers and biomass as precursors, conductive carbon frameworks are formed by controlling the carbonization temperature while retaining oxygen-containing functional groups. Although organic polymers are an essential source for the preparation of oxygen-rich carbons by partial pyrolysis, the ...

Coelomic fluid (CF) is the fluid enclosed in the main body cavity of echinoderms, which is equivalent to the haemolymph of invertebrates. The inorganic ion composition of echinoderm CF is slightly different from that of seawater12. Echinoderm CF also contains organic compounds, including amino acid...
Describes microorganisms that use energy from a chemical reaction of inorganic compounds (for example, oxidation of Fe(ii)) to fix carbon from CO2 into biomass. Mixotrophs Microorganisms using an inorganic electron source (for example Fe(ii)) in addition to an organic compound for their metabolis...
Modern formulations used for exterior wood coatings are often based upon water-borne acrylic dispersions, water-borne alkyd emulsions, or high solids (low volatile organic compound, VOC) alkyd systems and oil-based paints [253]. High VOC solvent-based systems have been mostly replaced in many Eur...
the shortcoming of the novel application of this chemical for EOR is that when its constituent contains halogen-anions, they cross the limit of greenness. Degradation of such ionic liquids produces hydrogen fluoride (HF) and hydrogen chloride (HCl) which are harmful to the environment. Additionally...
Half of the surfactant lipids correspond to dipalmitoylphosphatidylcholine, an unusual compound that contains the same saturated acid, palmitic acid (16:0), in the sn–1 and sn–2 positions. Surfactant also contains phosphatidylglycerol. The ability to synthesize and excrete surfactant develops during ...
The discussion of cofactor structure thus far has indicated that the molybdenum cofactor consists of a small organic component and the metal. In addition to this, a body of evidence is gradually accumulating which suggests that it also contains a peptide component. The original interpretation of the...
