Drinking Rubbing Alcohol According to the U.S. Department of Energy, rubbing alcohol, or isopropyl alcohol, is a simple, synthetically produced alcohol, comprised of eight hydrogen, three carbon, and one oxygen atom. It is has numerous medical, industrial, and household uses, and is not to be confused with ethanol alcohol found in liquor or wine. More importantly, drinking rubbing alcohol is strictly forbidden. Can You Drink Rubbing Alcohol? The short answer is no, it’s not! It is poisonous, and

The false aquisations of people’s livelihood has been looked down upon since the beginning of the Renaissance, and from there on, had multiple sayings and books about such topics. But no piece of literature shows mastery in this theme better than Harper Lee’s To Kill a Mockingbird, which takes place in Maycomb, a sleepy little town in Alabama, during the 1930s, a time period where the common man did not second guess people’s appearances. However that does not mean that there is not another, more

The objective of this two-part experiment was to in Part I, create 4-tert-butylcyclohexanone via oxidation of 4-tert-butylcyclohexanol to provide a source of ketone for reduction procedures. Part II of the experiment was conducted preforming a series of reduction reactions in effort to asses the diastereoselectivity of aluminum isopropoxide (MPV reduction), sodium borohydride (NaBH4), and L-selectride when reacted with 4-tert-butylcyclohexanone. The methods used for analysis were TLC, IR, and 1HNMR

The crude tetraphenylnaphthalene in a 25-ml Erlenmeyer flask and dissolved in boiling isopropyl alcohol (12 ml). The solution was cooled to room temperature and further cooled in an ice bath for 30 minutes. Crystallization of colorless crystals occurred. The product was collect in a Hirsch funnel and washed with isopropyl alcohol. The solid was left to dry over the weekend. The following lab period the solid was weighed (0.0483 g) and percent yield was calculated

Alcohol is abused daily from newly inexperienced drinkers in their teenage child hoods to older alcoholics that live on with their dreadful lives. People are consuming Alcohol beverages all hours of the day. The notice in alcohol contents is steadily increasing now more than the 1920’s when the 18 amendment was officially a federal law. Alcohol is changing year by year, causing more problems than helpfulness to human society in the twenty first century. The most known commonly known alcohols are

2. Experimental procedure 2.1. Chemicals and materials Melamine (99%), titanium dioxide with anatase (99.7%), isoniazid (ISN, >99%), isopropanol anhydrous (IPA, 99.5%), 1, 4-benzoquinone (BQ, ≥98%) and ammonium oxalate (AO, ≥99%) were purchased from Sigma Aldrich. The molecular structure and chemical properties of isoniazid are given in Table 1. Sodium hydroxide (NaOH, 99%) and methanol (MeOH, analysis grade) was purchased from Merck Millipore, Germany. Hydrochloric acid was purchased from PFP Matsunden

In this experiment, two alcohols, 1-propanol and 2-propanol, were oxidized through combining each with an excess amount of chromic acid solution. The purpose for conducting this experiment was to determine the reaction rate constant at which aldehydes and ketones formed from the respective oxidation of 1-propanol and 2-propanol. From this value, the half-life of the alcohol during the reaction could be derived. The progress of the reaction was tracked through the color change of the solution through

The anthraquinone dye experiment has the purpose to identify the anthraquinone dyes from unknown mixture by using thin layer chromatography (TLC) of the unknown fraction. An anthraquinone is an aromatic organic compound obtained by the oxidation of anthracene. To separate the compounds in the mixture, column chromatography and thin layer chromatography uses portioning of a sample between a stationary solid phase and a liquid mobile phase. As the stationary phase, they use either silica gel or alumina

Sports and soccer are social practices, which provide us a wide range of social interaction with a lot of passion and emotion. If we think about soccer and fandom, most of the people would picture a man, drinking beer and supporting the team, he is passionate about. Actually, this image is common, but according to Tofoletti (2013), female fans are more or less ignored, indeed “historical studies have demonstrated the exclusion of women from many sports and their highly restrictive participation in

2. Experimental method 2.1 Synthesis of PbSe and PbSe: Nd nanoparticles Neodymium doped PbSe samples (Pb1-xNdxSe) with x=0, 0.05, 0.10 at pH 5 were prepared by wet chemical precipitation technique, adding hydrazine hydrate as the precipitating agent at room temperature. Freshly prepared aqueous solution and analytical grade lead nitrate (Pb(NO3)2), neodymium oxide (Nd2O3) and selenium dioxide (SeO2) were used as precursor materials. Initially, 2 g of lead nitrate and 0.555 g selenium dioxide were

In this diagram we can see that acetaminophen consists of a benzene ring core, with hydroxyl and amide functional groups in proxy. Benzene (C6H6) is a hydrocarbon composed of 6 carbon atoms (92.26% of the molecule) and 6 hydrogen atoms (7.74% of the molecule) with alternating double and single bonds (resonance bonds) and is aromatic because of this. Benzene is a natural part of petroleum, usually <1.0% by weight, but is found in many things used today. Benzenes most common use is to produce ethylbenzene

1,3,4-Oxadiazole (1) is a heterocyclic compound containing an oxygen atom and two nitrogen atoms in a five-membered ring. It is derived from furan by substitution of two methylene groups (=CH) with two pyridine type nitrogens (-N=) [1,2]. There are three known isomers: 1,2,4-oxadiazole (2), 1,2,3-oxadiazole (3) and 1,2,5-oxadiazole (4). However, 1,3,4-oxadiazole and 1,2,4-oxadiazole are better known, and more widely studied by researchers because of their many important chemical and biological properties

Polyester is synthetic fiber which mainly derive organic chemical compound from coal, air, water and petroleum and have the ester linkage. According to How (2015), the chemical reaction between an acid and alcohol formed polyester where a combination of two or more molecules form large molecule whose the structure repeats throughout its length. Researched by Smith (n.d) mentioned that production of polyester is by the chemical reaction of ethylene glycol with either terephthalic acid or its methyl

The 1930’s was primarily encompassed of the Great Depression. The stock market crash of 1929 led to a downward spiral of the economy, and many families were forced into unwanted unemployment. While men faced the harsh reality of being out of work, woman transitioned themselves to accept the responsibility of being the primary “bread-winners” of the family. While women were becoming dominant in the work force, their profound role in society was overshadowed by many outdated Victorian Era gender biases

When you ask yourself - how will this glass of wine taste? You have to keep in mind that perception of taste will be different from person to person. For instance, if someone tells you that they can smell or taste a specific flavor (note), that doesn't mean that you will as well. In this short article, I will briefly explain what sensory evaluation is, who does it and why is it done the way it is. Let's begin. Usually, customers in restaurants or bars will taste a glass of wine to ensure that

PChem Experiment No. 3 Cryoscopic determination of molecular weight 1. Aims To determine the apparent molecular weight of benzoic acid in cyclohexane by creating a binary system and finding the different freezing points of the solutions. 3. Experimental Procedure A dry, empty freezing-point tube and its cork were weighed together. Carefully, 15-20g of pre-cooled cyclohexane was poured into the freezing-point tube, the tube recorked, and the whole thing was reweighed, to find the exact mass of the

Kaur,1985) which give sigmoid shape with (n-hexane, n-heptane and n-decane), i.e. show both negative and positive values at low and high mole fraction range. This can be explained as consequence of two opposing effects, the disruption of H-bonded alcohol aggregates by alkane molecules contribute negative VE whereas change in free volume and interstitial accommodation of smaller alkane molecules into the alkanol structure give negative contribution. The latter effect gets stoically hindered in 4-methylpentan-2-ol
