Finding the Ratio of Moles and Reactants in a Chemical Reaction Objective The objective of this experiment was to find the mole ratios of the reactants and products for the chemical reaction, without being given the products. Neda Samya Emma & Nisha Fri. 09/11 Procedure 1 I measured the temperature of NaCIO solution and “solution B” (using the same thermometer; temperature of solutions were equal). Then recorded my data in the table. 2 I poured 5.0 ml of NaCIO into a Styrofoam cup and then

formation of sp2 carbons can be difficult at times because of different reaction environments can cause different outcomes of the product, which generally yields impure products or the wrong products. However, by turning the reagent into a Grignard reagent, it is possible to get a SN2 like reaction to occur most of the time which helps in the formation of certain industrial and pharmaceutical compounds. The Grignard reaction allows sp2 carbons to react with losing its hybridization, and allows carbon

Introduction: Enzymes are specifically folded proteins which catalyse biological reactions in living organisms, they consist of an active site in which specific substrates can enter and a reaction takes place. As the enzyme does not permanently change structure, meaning the active site stays the same it allows multiple substrates to complete the reaction through single enzymes. The substrates are complementary to the active site of the enzyme and can be synthesised or degraded in order to create

Review of Literature Rust is a very complicated chemical process. Without some of the key steps needed to form rust the process would not be possible. Exothermic reactions and corrosion play key roles in the forming of rust. As do chemical reactions and the pH scale. The pH scale is used to measure how acidic or basic a certain solution is. The pH scale ranges from 0 to 14. Any solution that has a pH of 7 is neutral. An example of a neutral solution (pH of 7) would we water. A pH less than 7 is

Sugar in Coke Lab Report Sheet: Raghed Odeh 10/18/2017 Provide a brief statement of the purpose of this activity and explain the idea behind a calibration curve (this can be done before class and valuable insight can be gained by watching the “weblets” (online prelab lectures available in the course content of D2L). The purpose of this lab is to determine the amount of sugar (in grams) in a can of coke, learn how to make solutions quantitatively and learn how to make and use a calibration

Introduction Chemical reactions occur all around us, even in us. Millions of reactions occur in our bodies every day, let alone outside of out bodies (ChemHealthWeb.gov, 2015). Human bodies create energy by using glucose in a series of chemical reactions to release energy. This is called respiration and it occurs in all living cells. Some chemical reactions are visible such as oxidation. This is a reaction between some metals and oxygen. Electrons jump from the metal to the oxygen and form a layer

Introduction The purpose of this lab was to introduce chemical development as a way to develop latent fingerprints and to demonstrate two of these methods: cyanoacrylate fuming and iodine fuming. These two methods are regularly used to develop latent fingerprints. Cyanoacrylate (or superglue) fuming was discovered as a way to develop prints in the late 1970s. The fumes of heated cyanoacrylate react with the bodily fluids of a fingerprint. The fumes attach to moisture, so evidence with excessive

Name Instructor Course Code Date of Submission A metal Complex Stoichiometry Introduction The goal of this experiment was to determine the mole ratio of ortho-phenanthroline and Fe2+. In addition, the formula of Fe(II) metal complex was determined using an aqueous solution. The chemical formula of the metal complex in aqueous solution is expressed as follows: Fe^(2+) (aqueous) + ‘n’ ortho-phenanthroline (aqueous) → Fe(ortho-phenanthroline) n^(2+). Chemically, the two substances form a metal complex

studying chirality. The bromination of the substituted alkenes was known as an oxidation reaction and it produced different stereoisomers based on the alkene’s geometry. The E-stilbene when exposed to bromine produced dibromostilbene. Three products can potentially form from this reaction which are meso, D, and L stilbene bromide. The goal of this experiment was to identify which stereoisomer predominated in the reaction and determine the most favored cation intermediate. The first step of the mechanism

Iodination of Salicylamide Purpose The purpose of this experiment is to study the directing effects of substituents on an aromatic ring. Aromatic rings do not undergo electrophilic addition reactions instead they undergo electrophilic aromatic substitution. The study will be made from the reaction of the electrophile, iodide ion with sodium hypochlorite, with salicylamide that has a hydroxyl group (ortho-/para- directing) that is highly activated, electron donating, and an amide group (meta- directing)
