For the Identification of an Unknown Compound lab, the physical properties, along with the IR and the H1 NMR will be used to determine the molecular structure and identity of the unknown compound. For the physical properties, the smell, color, state, solubility and the refractive index will be used. Then, the IR and H1 NMR be obtained using the unknown compound given during the lab. The IR and H1 NMR will play a major role in determining the molecular structure of the compound because the stretches

proteins which act as effective catalysts for biochemical reactions within an organism. Enzymes are distinct from one another; they attach themselves to specific slots on substrates called active sites to lower the activation energy to start the chemical reaction. This is represented by the lock and key model, where the shape of the enzyme directly corresponds to the substrate to carry out a specific job. An enzyme is able to be used until it becomes denatured, or when the active spot of the enzyme

Enzymes are proteins that are made by living cells. They act as catalysts, speeding up the chemical reaction process, remaining unchanged before and after. They do so by lowering the activation energy, meaning when they are present, less energy is required for the reaction to occur. The enzymes act on a substrate during the process. A substrate is any compound the enzyme bonds with. However, the substrate must match a specific shape for the two to bond properly. This is known as the key and lock

Christian Rodriguez Mrs. Gentry AP Biology September 27, 2015 Lab Abstract Enzymes are proteins produced by living cells. In an enzyme, the substrates bind with the active site of an enzyme, breaking them down into other molecules. Enzymes acts as catalyst which lower the reaction energy and allows it to take place in less time and at lower temperatures. Enzymes can be used in a reaction without actually being used up; therefore, they can be used reversibly. Temperature, salt concentration, substrate

A miniscale diels-alder reaction was performed between the conjugated diene 2,3dimethyl-1,3 butadiene and a substituted alkene such as maleic anhydride in order to produce a substituted cyclohexane. The substituted cyclohexane produced was 4,5-dimethyl-4-cyclohexene-cis-1,2-dicarboxylic acid anhydride. A diels- alder reaction does not have an intermediate state, meaning that bond breaking and bond making occurs at the same time. Heat needs to be applied in order for the reaction to occur and it is

1. Part A.2. What is the formula and the color of the gas that is evolved? The name of the brown colored gas is nitrite, and its formula is NO2 (Beran, 2014). 2. Part B.1. When the NaOH solution is added, Cu(OH)2 does not precipitate immediately. What else present in the reaction mixture from Part A reacts with the NaOH before the copper(II) ion? Explain. The other compound present within the reaction mixture that came from Part A is water, H2O, which reacts with the NaOH before the copper(II) ion

TITRIMETRIC ANALYSIS 3.7.1. BASIC PRINCIPLES In titrimetric analysis we volumetrically measure the amount of reagent, often called a titrant, required to complete a chemical reaction with the analyte. A generic chemical reaction for titrimetric analysis is ����+����→���������������� Where: a moles of analyte A contained in the sample reacts with t moles of the titrant T in the titrant solution. The reaction is generally carried out in a flask containing the liquid or dissolved sample

CRYSTAL STRUCTURES CRYSTAL STRUCTURES • Have you ever wondered how atoms assemble into solid structures? • How does the density of a material depend on its structures? CRYSTAL STRUCTURES • Solid materials can broadly be classified as crystalline and non crystalline (amorphous) solids. • In crystalline solid the arrangement of atoms is in a periodically repeating manner whereas no such patterns are found in a non-crystalline solid. CRYSTAL STRUCTURES • 2 types of crystalline solids:
