IB Chemistry SL: Topic 4 Latest Version Graded A Ionic Bond Electrostatic attraction between oppositely charged ions Covalent Bond Electrostatic attraction between a pair of electrons and positively charged nuclei, formed as a result of electron sharing Metallic Bond Electrostatic attraction between a lattice of positive ions and delocalized electrons Polyatomic ions ions with more than one element e.g. CaCO3, Al(OH)3, Mg(NO3)2, (NH4)2SO4, Ba3PO4, LiHCO3 Lattice ions arran...

Antigen Shape to Antibody Shape - Answer-Simple = Pocket Large = Groove Complex = Extended Surface Type of chemical bond used with antibodies - Answer-1)Electrostatic 2) Hydrogen bonds 3) Van der Waals forces 4) Hydrophobic interactions Cross reactivity - Answer-The biding site can accept a shape close enough in shape and get reaction or a stable structure Ex. Penicillin and other B-lactam Diagnostic tests for antibody/antigen - Answer-ELISA Lateral Flow test (pregnancy hCG) Immunofl...

The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds. D) Individual hydrogen bonds in liquid water exist for many seconds and sometimes for minutes. E) The strength of a hydrogen bond depends on the linearit...
