The Autobiography of a Coin Written by Frank L. Holt Illustrated by Bob Lapsley Additional reporting by David Warsh I was born in the fires of an ancient forge in the hills of the Hindu Kush. Amid the clatter of hammers and the chatter of Greek‚ I paused on a battered anvil for the final pangs of my creation. Beneath me lay a hardened die bearing the image of my king; atop me pressed another‚ etched with horsemen and some mirror-image words. Then the hammer struck‚ hard and heavy‚ ringing out

the content of chloride in an unknown salt‚ using gravimetric analysis. Theory: The salt chloride content is easy to find because it is slightly soluble‚ making it possible to turn it into a precipitate. A precipitate reaction can be done using silver to isolate the specific ion. Ag+(aq) + Cl-(aq) --> AgCl(s) Despite AgCl(s) being highly insoluble‚ some of the substance will still dissolve. This dissolved portion can be calculated. AgCl(s) => Ag+(aq) + Cl-(aq)

FILM STRUCTURE FILM STRUCTURE What is motion picture film? The American National Standards Institute (ANSI) describes it as “a thick flexible strip of plastic‚ complying with a dimensional standard as defined within‚ whose use is specific to the process of manufacturing a motion picture.” That definition leads to about a dozen pages of further definitions about various aspects of motion picture film. For our purposes‚ let’s take a look at how film is made‚ and how an image is formed on that film. THE

Acetone is a good solvent for Sn2 reactions because it is a polar aprotic solvent. We will be examining Sn2 reactions with an ethanolic solution of silver nitrate. The silver ion coordinates with a lone pair on the halogen which begins to weaken the carbon-halogen bond. In the rate determining step‚ the carbocation and solid silver halide is formed. We will monitor the reaction by looking for the formation of the solid. R X Ag+ R X Ag R+ + AgX Procedure: Sn2 Assemble
