In this experiment‚ the objective is to successfully perform an SN1 reaction to determine the reactivity of tert-butyl chloride‚ through the usage of sodium iodide/silver nitrate reagents and to synthesize tert-butyl chloride. The tert-butyl chloride was synthesized through the use of separation (aqueous and organic layers) and distillation. Tert-butyl chloride is the alkyl halide which is being synthesized throughout the course of the experiment. Alkyl halides are derived from alkanes. Once an alkane

precipitation reactions in order to get a reliable system of producing the rings. • To investigate the effect of passing a D.C. current through the gel solution on the production of Liesegang rings. Main findings • The lead nitrate/potassium iodide and cobalt chloride/ammonium hydroxide reactions both formed bifurcations. The cobalt chloride/ammonium hydroxide reaction was then investigated under different conditions until discernable Liesegang rings had formed. • It was found that the

Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

Niepce called his invention heliographs meaning sun drawings‚ which required eight hours of exposure. Later in Paris Louis Jacques Mande Daguerre invented a similar process called daguerreotype. It involved the use of a silver plate sensitized by iodide and then exposing it in the camera obscura‚ and then the plate was kept on mercury solution and finally fixed by salt solution. The daguerreotype produced a much clearer picture than the previous heliograph and the exposure time was also reduced.

The compound is the substance that can be two or more elements that can be changed. Water is a compound. It contains both Hydrogen and oxygen that can stand alone by itself. The mixture is when two different substances that are blended together. The air is a mixture of these elements carbon dioxide‚ nitrogen‚ and other stuff. Most mixtures are known to be naturally. The main difference between the compound and the mixture is how they are combined. In the pure substance‚ the only way to know if
