Carmel Vijay Chemistry Lab 227 Zach Sailor November 8, 2013 Observing Chemical Reactions Beginning Question When a chemical reaction takes place, is it always accompanied by a physical change? Explain. Bunsen burner The Bunsen burner is a device in use these days to safely burn a continuous stream of a flammable gas such as natural gas, propane, or butane. The completeness of the combustion reaction affects the amount of air mixed with the gas stream. When a gas stream is well mixed

Second Order Reaction Kinetics Abstract The objective of this experiment was to determine if the specific rate constant of the reduction reaction of hexacyanoferrate (III) ion with ascorbic acid (C6H8O6) is affected by the ionic strength of the solution and the charges of the ion species within the solution. A Cary Bio 50 Spectrophotometer and its associated software was used to measure the absorbance of the solution at a wavelength of 418 nm. Analysis of the data collected supports the conclusion

Silly Putty "Stretch it, pull it, Bounce it" (Ball of fun) Introduction: Silly putty is a toy that kid totally enjoy or chemical compound made of silicone and boric acid. It is composed of flexible molecules that give the material flow. Silly putty is a viscoelastic liquid and is a mixture of water, glue, and boron [1]. The word, viscoelastic is a compound word, visco means "resistant to flow" [Dictionary] and elastic describes a material that when stretched returns to its original form. In

BOILING POINT OF ORGANIC COMPOUNDS ABSTRACT One of the methods to identify an organic compound is by determining its physical properties. In this experiment, we will only looking for their melting point and boiling point on the effects of the chemical structures. Melting point is defined as the temperature at a specific pressure which the solid and liquid phases are in equilibrium with each other. The boiling point is used to characterize a new organic liquid and knowledge of the boiling point

accelerated by the fact that her husband, Frank, had been stricken by a debilitating illness. It had surprised Mary somewhat that she was able to land a position quickly as controller and office manager for Hewsen Chemical Inc., a small, privately-held producer of specialty chemicals used in testing labs and other manufacturing firms.

CHEMISTRY CHEMISTRY (CLASSES XI–XII) Rationale Higher Secondary Stage is the most crucial stage of school education because at this stage specialised discipline based, content oriented courses are introduced. Students reach this stage after 10 years of general education and opt for Chemistry with a purpose of mostly for pursuing their career in basic sciences or professional courses like medicines, engineering, technology and studying courses in applied areas of science and technology at tertiary

CHEMICAL CONVERSIONS Acylation Acylation (rarely, but more formally: alkanoylation) is the process of adding an acyl group to a compound. The compound providing the acyl group is called the acylating agent. These are used to form aryl ketones. Because they form a strong electrophile when treated with some metal catalysts, acyl halides are commonly used as acylating agents. For example, Friedel-Crafts acylation uses acetyl chloride (ethanoyl chloride), CH3COCl, as the agent and aluminum chloride

The lessons presented this week were informative and interesting. Choosing only one reason to study secular literature is difficult to do, but, I have chosen to expand on the indication that literature helps us to understand human behavior. I chose this area because as I am reading books and other material, I am building the visual picture of what, how, and why the characters act or react as they do. And sometimes I am surprised that the way I envisioned the outcome is completely different than
