What happens to NaCl (salt) in water? What are the physical and chemical properties of bromine? Compare the properties of an ionic material such as sodium chloride with a room-temperature ionic liquid. Explain the difference. Sodium metal is extremely reactive with chlorine gas. Is this a phys...
Describe the chemical structure of a lipid. Explain how stable monosaccharides are assembled into energy storage and structural polymers. Give examples. Mention some of the characteristics of lipids. Describe the catabolism of fatty acids, proteins, and carbohydrates. ...
Chemical properties of cellulosic fibers include good resistance to alkalis.Excessive bleaching will harm cellulosic fibers,although carefully controlled bleaching is less detrimental.Such properties as the withstanding of high water temperature permit laundering of cellulosic fibers with strong detergent,...
In this work, a new model of SOM decomposition is presented. The SOMDY model is based on an advanced description of SOM chemical quality by 13C-CPMAS NMR instead of traditional C/N ratio. The model includes also the effects of physical aggregation of organic matter. SOMDY was calibrated ...
Final Summary: In summary, chlorophyll plays a vital role in photosynthesis by absorbing sunlight, converting it into chemical energy, and facilitating the transformation of water and carbon dioxide into glucose and oxygen. --- Show More
Viscose rayon loses 30%～50%of its strength when wet,thus requiring great caution in laundering.It recovers strength when dry.It has very poor elasticity and resiliency.It also shrinks appreciably from washing. Viscose fiber swell in water.This causes the fabric to shrink.Swelling and shrinkage ...
The community of microorganisms inhabiting a specific environment, such as the human gut - including bacteria, fungi, archaea, viruses, protozoa, and others - is known as the microbiota. A holobiont, in turn, refers to an integrated ecological unit where microbial communities function and interact...
How is the structure of the stomach related to its function? What is the function of proteins and carbohydrates that are embedded in a cell membrane? Discuss the biochemistry of carbohydrates. Include the chemical structure of the most relevant carbohydrates from a food source and t...
