Once the vehicle gets into a crash the air bag pops out. The air bags are filled nitrogen gas. Hazardous sodium metal is also produced with the nitrogen so the potassium nitrate adapts with the sodium to make the hazardous sodium oxide less harmless. The uses of the stoichiometry calculations are to figure out

would mimic the reduction taking place in this experiment is hydride addition using sodium borohydride‚ NaBH4. Normally an alternative to this oxidizing agent would be lithium aluminum hydride‚ LiAlH4‚ however this reagent would also react with the ester portion of our starting reagent. The effect of reducing the ketone via hydride addition is that product is entirely a racemic mixture (McMurry 696). After the initial reaction the product was isolated using a series of vacuum filtrations‚ ether extractions

Stoichiometry in the Industry (Mining Industry) Prepared By: Ryan Khan and Michael McDonald Course code: SCH3U1 Teacher: Miss Kedzia Due Date: 22/4/2013 Date Submitted: 22/4/2013 What Is Stoichiometry? Stoichiometry as defined by our textbook is “the study of the quantitative relationships among the amounts of reactants used and the amounts of products formed in a chemical reaction”. Basically‚ Stoichiometry is the science of counting and studying the relationship between the amounts

Crosslinked is one manner in which monomers link together. In this method‚ separate polymer chains are connected via bonds between the individual polymer chains. 2. We discussed how polymer linking and structure contribute to its properties. How would you expect the density‚ elasticity

Polymerase chain reaction The Polymerase chain reaction (PCR) is a biochemical technology in molecular biology to amplify a single or a few copies of a piece of DNA across several orders of magnitude‚ generating thousands to millions of copies of a particular DNA sequence. Developed in 1983 by Kary Mullis‚ PCR is now a common and often indispensable technique used in medical and biological research labs for a variety of applications. These include DNA cloning for sequencing‚ DNA-based phylogeny

Abstract: The objective of the experiment was to prepare Benzilic acid by multistep synthesis starting with benzaldehyde. In this setup however‚ product of the first step‚ Benzoin‚ is provided thereby omitting the first step involving the conversion of benzaldehyde. For this experiment‚ the microscale techniques of reflux‚ crystallization‚ and melting-point determination were used. Utilizing these techniques a product yield of 93% for benzil and 57% for Benzilic acid was obtained‚ as well as
