Ammonia production

Segmented polyurethanes can be represented by three basic components in the following general form: P-(D(CD)n-P)n Where P is the polyol, D is the diisocyanate and C is the chain extender. Polyol, or the so-called soft segment, is an oligomeric macromonomer comprising a “soft” flexible chain terminated by hydroxyl (-OH) groups. The chain extender is usually a small molecule with either hydroxyl, or amine end groups. The diisocyanate is a low molecular weight compound that can react with either the

Aromaticity and reactions of pyridine Introduction The structure of pyridine e considerably resembles that of benzene. It may be formally derived from the structure of benzene through the exchange of one ring carbon for a nitrogen but, is pyridine which is structurally and electronically allied to benzene, also aromatic?. Pyridine is aromatic based on the following facts. The protons of pyridine show chemical shifts in the NMR spectrum that are ordinary of aromatic protons. Furthermore, electrophilic

A heating bath is used in the laboratory to allow the chemical reaction to occur at an elevated temperature around 1000C. The beaker is a glass vessel which contains the chemical solutions for the purpose of coating. It is placed in the electroless bath where the chemicals are being heated up. The glass rod is used to stir the chemical where the magnetic stirrer is not necessary. The tongs are used to lift the bath after the coating is completed. Tri-sodium citrate and thallium acetate are the chemicals

If you’re on your lunch break and you’re hungry, what is the quickest and simplest thing to do? While some people choose to do meal preps, most people will commonly go get fast food. Although, fast food might be the simplest, quickest, and cheapest option, it most certainly will not be the best option for you. Unfortunately, what many people do not realize and need to be aware of is what they are actually putting into their bodies, and the harmful effects it can have on their health both physically

PART A: Procedure: Making Solution A First, obtain 10 mL of distilled water using a graduated cylinder, then pour into one 50 mL beaker. Next, obtain 0.100 g of sodium iodate (NaIO3) using a digital scale (0.104 g actually used). Then obtain 0.200 g of sulfamic acid (H3NSO3) using a digital scale (0.210 g actually used). Finally, add the sodium iodate into the beaker containing the distilled water followed by the addition of the sulfamic acid. Solution A is now complete. Making Solution B

Do you ever sit and ponder what the phrase keeping the lights on means to you? If this question has never crossed your mind it should. Behind every wall, outlet or light switch there is a dedicated workforce behind it that power the lives of many Americans from Electric Companies to Power Plants producing the electricity. We as American’s today do not understand and take for granted having electricity. Many of us think we do not care where my electricity comes from as long as we have it. You

February 5, 2012   Chemistry 1211L - 146 - Spring 2012   Procedure The Synthesis of Cobalt Oxalate Hydrate Place 100 ml of distilled water in a 250-ml (or 400-ml) beaker. Add 1.26g of oxalic acid dihydrate (H2C2O4.2H2O) and 1 ml of concentrated ammonia. Stir the mixture until the solid has dissolved completely. Dissolve 2.34 g of cobalt chloride hexahydrate (CoCl2.6H2O) in 100 ml of water in an Erlenmeyer flask. While stirring the oxalic acid solution constantly, add the cobalt chloride solution

The goal of the project was to characterize an "unknown" organic acid in order to make a proper identification of the acid, while learning proper techniques for scientific measurement and analysis of error. In order to ensure the most accurate data, a purification was performed by the process of recrystallization. To perform the recrystallization the powder was dissolved in a minimal amount of hot ethanol/H2O solvent that allowed the unknown powder to crystallize properly when cooled. This process

Deborah Bell April 17, 2012 Chemistry 1212K Lab Synthesis Report Introduction In this Chemistry Lab the main objective is to perform accurate chemical analysis for the quantity of elements and compounds in a sample. There will be a compound made then synthesized. The methods used were acid-base titrations, redox titrations, gravity filtration, and distillation. General conclusions included Procedures Weight of Crucibles 1. The first experiment is Preparation of a Cobalt Amine
