What material is the exoskeleton of arthropods comprised?
The exoskeleton of arthropoda is made of a tough protein called chitin, a long chain polymer comparable to cellulose. It fills the same role as the protein keratin in other animals where it would be found in hair, nails, hooves, claws, beaks, etc. Some arthropods, like crustaceans, further harden their chitin exoskeleton by biomineralization with calcium carbonate. Because it is inflexible, the organism has to periodically shed it (moult) in order to grow.
What atoms are in chitin?
Chitin is actually a polymer that can be made up of any number of monomer subunits. The monomer for chitin is N-acetyl-D-glucosamine, which has a chemical formula of: (C8H13O5N)n Therefore, each monomer is made up of 27 atoms.
Chitin is a polysaccharide with what atoms attached to the glucose backbone?
Chitin is a polysaccharide. So, it is a polymer of many monosaccharides. In the case of chitin, the monosaccharide subunit that makes up it polymeric structure is N-acetyl-D-glucosamine.
How do you prepare colloidal chitin from chitin flakes?
To prepare colloidal chitin from chitin flakes, the flakes are typically treated with an acid, such as hydrochloric acid, to remove calcium carbonate impurities. Then, the chitin flakes are treated with a base, such as sodium hydroxide, to deprotonate the amine groups and convert the chitin into colloidal form. The resulting colloidal chitin can be used in various applications including in the food and cosmetic industries.
What is the general term for the process where fluorine atoms are converted to fluoride ions?
The general term for the process where fluorine atoms are converted to fluoride ions is called fluorination.
Why do most solids expand on heating?

What is a bees wing made out of?
Insect wings are made of chitin, the same material from which their exoskeleton is made. Chitin is a polysaccharide which forms fibrous molecules in which hydrogen atoms bond to produce extra strength. The veins in the wing also give it extra support. Insect wings are one of nature's lightest structures and contain no bones or muscles.

What is the general formula for benzene?
The general formula for benzene is C6H6. Benzene consists of a hexagonal ring of six carbon atoms with alternating single and double bonds between them, along with six hydrogen atoms attached to the carbon atoms.
What is the number assigned to atoms to show general distribution of electrons among bonded atoms called?
Oxidation Number
Are particles smaller then atoms?
particle is a general term. subatomic particles are smaller than atoms. dirt particles, for example, are much bigger than atoms
How many times larger is the number of hydrogen atoms than oxygen atoms in a polysaccharide?
There are twice as many hydrogen atoms as oxygen atoms in a polysaccharide. The general formula for this is Cx(H2O)y.
