Demonstrate the concept of resonance and formal charge by drawing ALL resonance forms of the phosphate anion and labeling the formal charge on each atom on one of the structures. Determine the bond order in phosphate.
Phosgene, a substance used in poisonous gas warfare during World War I, is so named because it was first prepared by the action of sunlight on a mixture of carbon monoxide and chlorine gases. Its name comes from the Greek words phos (light) and genes (born of). Phosgene has the following elemental composition: 12.14% C, 16.17% O, and 71.69% Cl by mass. Its molar mass is 98.9 g/mol.
(d) Using average bond enthalpies, estimate H for the formation of gaseous phosgene from CO(g) and Cl2(g).
In developing a Lewis structure for NO +, the nitroxonium ion, how many valence electrons must you account for?
