structure and bonding give a better explanation of the total number of electrons that bond to form a new compound. It also gives both the geometry of an atom and the non-bonding electrons. Answer and Explanation:1 SiO2 O::S::O From the above lewis ...
Surface charge is a critical issue for various types of glass processing including surface finishing (polishing) and cleaning. Unlike monomeric silicic acid with a pKa of 9.8, glass surfaces can have variable pKa values as determined by extent of Si–O–Si bonding, composition, and structure. Th...
