Information collected: Fireworks need a colorant (to make the pretty colors), a propellant (to shoot the firework into the sky), a burst charge (to blow the firework apart), and an oxidizer (provides oxygen for the burst charge reaction). The burst charge can be any of a number of available explosive chemicals. Oxidizers provide oxygen for the fuel to burn. Common oxidizers are chlorate (CIO3¬), carbonate (CO32-), sulfate (SO42–) and nitrate (NO3¬) ions. Usually the colorants are hot, glowing metals. In the flame test for elemental identity, compounds containing strontium ions yield a bright red flame. Copper (II) ion flames are blue. If we mix strontium chlorate with copper (II) chlorate, the firework will be purple! Common propellants used in fireworks contain carbon and sulfur. The "glue" is often dextrin, a cellulosic polymer made from connected units of C6H1206. The Problem In a blue-burst firework, copper (II) chlorate reacts with carbon to make copper (II) chloride and carbon dioxide. The skeletal structure of a propellant (C6H9N3012) is shown below (dashed lines show connections between elements). Terminal O #2 Terminal O#1 N Formal charge: find formal Atoms needing formal charge Central O charge for the indicated atoms H--- to help find the "best" structure; show your work in the provided table.
