Purpose The purpose of this lab was to measure the temperature of a solution to see how much energy was gained/lose during the reaction between the NiCl2 and Ethylenediamine. In this experiment we were also finding how many Ethylenediamine will bind to Ni+2 in an aqueous solution. By measuring the change in evolved heat, it’s possible to find the maximum number of Ethylenediamine molecules that have attached to each ion. Procedure Gather materials Analytic Balance Pasco with temperature probe Styrofoam cup Tape 5 M Ethylenediamine 0.998 M NiCl2 10 mL Pipet 2 mL

Conclusion In this lab, the reactivities of different types of hydrogens, including primary, secondary, tertiary aromatic, aliphatic, and benzylic hydrogens, were analyzed. The experiment was conducted twice, simultaneously. One set of test tubes containing bromine, dichloromethane, and one of toluene, ethylbenzene, tert-butylbenzene, cyclohexane, methylcyclohexane, or more dichloromethane (control), were exposed to UV light; the other equal set of test tubes were placed in a fume hood with the light off. This set of test tubes was not fully in the dark.

The following lab period the solid was weighed (0.0483 g) and percent yield was calculated (65.5%) with the limiting reagent being tetraphenylcyclopentadienone. The melting point was determined. The first melting point was 204-204.9 °C and the second melting point was 215.6-215.9°C. Finally, an infrared spectroscopy was obtained for the

The ethyl-4-aminobenzoate is similar to benzoic acid, in that it has a nonpolar ring and has polar attachments. The nonpolar ring is what makes it soluble in diethyl ether. Each compound is soluble in water because they

The most known commonly known alcohols are Isopropyl and Ethanol they're both used every day for cleaning wounds to be used as fuel for operating an automobile for and kinds of transportation. “Isopropyl is used to help fight bacteria in open cut wounds on humans and animals. ”(Elaine 9) Ethanol is used for alcohol to be consumed to help but also destroy human lives. Ethanol is mainly used and consumed by automotive technology for gasoline and biofuel productions.

Tetrachloroethylene is a clear, nonflammable liquid, and is a commonly used solvent that has been in commercial use since the early 1900s. It can be found in water repellant, paint remover, printing ink, glue, sealant, polish, and can also be used to make other chemicals. Although it has been detected in small amounts in the air and in some sources of drinking water, the most common source of exposure is in the industries that use this chemical. Such industries are the dry-cleaning business, where it is used as a solvent, and businesses that degrease and clean metals, or need to dissolve greases and oils from fabrics. Because Tetrachloroethylene is a chlorinated hydrocarbon, it is a central nervous system depressant, and can easily enter the body through respiratory or dermal exposure, allowing this to be taken into the body dangerously easy.

WD- 40 is a common product that every household typically has on hand due to its useful purpose of preventing your door from expressing its discomfort, also known as that high-pitched squeak that nobody enjoys hearing to. WD-40 is composed of 3 main substances. This includes decane (C10H22) which is also a common ingredient of gasoline (it helps WD-40 remain a liquid at cold temperatures), dimethyl naphthalene (C12H12) which comes in 10 forms aka isomers, and carbon dioxide (CO2). “Decane can be extracted from various petroleum solvents, such as Stoddard solvent, via fractional distillation” (Sciencemaddness Discussion Board, 2016), (fractional distillation - separation of a liquid mixture into fractions differing in boiling point), which is also very toxic if consumed and should always be stored in tightly-closed bottles away from heat. Dimethyl naphthalene, not only is it the next main ingredient used in WD-40, but it is also used as a plant growth regulator (it naturally occurs in potatoes to promote sprouts).

INTRODUCTION A gas chromatograph (GC) can be utilized to analyze the contents of a sample quantitatively or in certain circumstances also qualitatively. In the case of preparative chromatography, a pure compound can be extracted from a mixture. The principle of gas chromatography can be explained as following: A micro syringe is used to inject a known volume of vaporous or liquid analyte into the head or entrance of a column whereby a stream of an inert gas acts a carrier (mobile phase). The column acts as a separator of individual or chemically similar components.

The vapour is conducted by a heating element inside the device which heats up the liquid put in the devices. This liquid is called e-liquid. E-liquid is a mixture of: glycerine propylene nicotine flavouring Cigarettes where made in the 9th century by Mexicans in Central America. It was first used for religious purpose by the Mayans and the Aztecs. The cigarettes were later introduced to the French in 1845.

There are two methods of obtaining cyclohexane. These two methods are fractional distillation of naphtha and hydrogenation of benzene. Research suggest that the hydrogenation of benzene is the most economical way to create our chemical of choice. According to ICIS, cyclohexane is used in the production of adipic acid used to

The effects of alcohol on Biological Membranes. Introduction In this experiment it will be analysed the damage alcohols can have on biological membranes. Membranes are made up of lipids and proteins. Membranes usually help maintain the balance in a cell as it holds all the cellular materials.

Purpose/Introduction The process of recrystallization is an important method of purifying a solid organic substance using a hot solution as a solvent. This method will allow the separation of impurities. We will analyze Benzoic Acid as it is dissolved and recrystallized in water and in a solvent of Methanol and water. Reaction/Summary
