Chemistry Write a 500 word essay on The Valence Shell. Describe how the electron configuration in this determines the type of bonds between atoms. Cite at least two academic sources and use APA style for all your papers.
The dissertation is about the production of chitosan bioplastic by mixing in chitosan powder and acetic acid. Glycerol and litmus solution is also added to produce a bioplastic with different properties. After the bioplastic is made it is tested using DSC, TGA, IR Spectroscopy and SEM and Brinell Hardness Test. Thus, it is VERY IMPORTANT […]
