Experiment 23: Synthesis of an Alkene April 5‚ 2013 Purpose: Results and Discussion The weight of our n-Butyl Bromide sample (actual yield) was 0.09g. The percent yield was found to be 4.38%. Only 0.09g of the theoretical 2.055g yield was obtained. The boiling point was 104° C‚ which is higher than the literature value of 101° C. This is due to the sample being somewhat impure‚ as impurities tend to increase boiling point. When IR spectroscopy was performed‚ there were no OH stretches

Acid Rain and its Chemistry Acid rain is a type of pollution that is becoming a major threat to our planet and is need of attention. Acid rain has significantly increased ever since the industrial revolution‚ and now around the world‚ countries like Russia‚ China‚ and those in Europe are facing increasing levels of acidity in their rain. Not only is it becoming more acidic but it is also spreading by the pumping of sulfuric gasses deeper into the atmosphere from of the use of taller smokestacks

Protein Synthesis Worksheet 1. 2. a. Protein synthesis began in the nucleus. b. Chromatin is a diffuse mass located in the nucleus where genetic material is found. c. A gene is a sequence of nucleotides‚ it is important because they form the template and these templates are used for synthesizing proteins. 3. a. Transcription is the first step of protein synthesis it uses a sequence of DNA nucleotides to produce a sequence of RNA nucleotide. b. RNA polymerase bonds to RNA nucleotides together

Synthesis Essay In today’s society‚ language is one of the most important and most used things in everyday life. Language is one of the most effective and efficient ways of communicating with one another‚ animals‚ and God. It can be used as a mirror‚ tool‚ or a weapon. The reason I think language can be used as a mirror is because people use language to directly reflect who they are as a person. For example‚ if you have heard someone using improper grammar or slang‚ it may lead you to believe

EXTRACTON OF SASAME OIL USING DIFFERENT METHODS OF EXTRACTION FOOD PROCESSING PRACTICAL (TFT 709) BY GROUP THREE MEMBERS ISMAILA AYUBA RAMADAN Submitted to Department of Food Technology University of Ibadan Lecturer-in-charge Dr. Akinoso Febuary‚ 2012 Abstract Oil extraction was carried out using two different extraction method (water and solvent) and the yield for different method were obtained. The free fatty acid for different oil was also determined

Industrially produced trans fats are formed during partial hydrogenation‚ a process used by the vanaspathi industry to harden and stabilize liquid vegetable oils. Hence the detail study was undertaken in four selected food service operation. The selected food service organisations were observed at various functional areas with a checklist with the objective to assess the awareness on trans fat among the food

Neutralization reactions involve the reaction of an acid and a base to produce a salt (ionic compound) and water. Acid + Base ( Salt + Water □ In this lab‚ sulfamic acid (a weak acid which contains one acidic hydrogen) will be used: H2NSO2OH(aq) + NaOH(aq) ( NaOSO2NH2(aq) + H2O(l) (Net Equation: H+(aq) + OH-(aq) ( H2O(l)) □ Titration is a process of neutralization □ Titration is commonly used to determine the concentration of an acid or base

cell is more difficult. DNA of an eukaryotic cell is in chromatin form to fit into the small nucleus for the replication to occur‚ first the DNA should open. This is because it is harder for eukaryotes to carry out DNA synthesis. Replication of DNA in a prokaryote is different from a eukaryote. In a prokaryote they have a single origin where the replication process starts. Also eukaryotes synthesize the same time they are being transcribed‚ and ribosomes will be active on the single mRNA while it

call the Bronsted-Lowry definition of an acid‚ which is the main focus of this lesson. !!!What is a Bronsted-Lowry Acid? What makes a solution an acid? There are different definitions proposed by different scientists about what makes an acidic solution. Particularly‚ there were two scientists who independently proposed essentially the same theory about the definition of acids and bases. In 1923‚ Johannes Nicolaus Bronsted and Thomas Martin Lowry‚ from Denmark and England‚ respectively‚ came up
