8.07 Work File: Oxidation Reduction Reactions 1. What is the difference between an oxidizing agent and a reducing agent? The oxidation number (overall charge of the atom) is reduced in reduction and this is accomplished by adding electrons. The electrons‚ being negative‚ reduce the overall oxidation number of the atom receiving the electrons. Oxidation is the reverse process: the oxidation number of an atom is increased during oxidation. This is done by removing electrons. The electrons‚ being

Biodiesel production yields varied from 81.7 to 88.0 (wt%)‚ the lowest yields being the ones obtained using waste frying oil and lard alone as raw materials. The obtained products fulfilled most of the determined quality specifications according to European biodiesel quality standard EN 14214. Minimum purity (96.5 wt%) was closely obtained when waste frying oil was used alone and when 0.2% of lard was incorporated in the raw material (96.3 wt%); however‚ it ranged from 93.9 to 96.3 (wt%)

neutralization reaction of ethanoic acid and sodium hydrogen carbonate Cristina Li 17th April 2017 Introduction The hypothesis is the balloon will be bigger and bigger with the increase of vinegar. The chemical reaction between the baking soda and vinegar produces bubbles of carbon dioxide gas as part of this acid-base reaction. Sodium hydrogen carbonate (baking soda) reacts

this goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction‚ we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid‚ and then Silver Nitrate

Gun Control and Crime Reduction Solution The solution I propose is to deregulate firearm laws and eliminate criminal protection zones through the Buckeye Firearms Association in the State of Ohio. Problem To focus on violent crime or crime reduction in Ohio‚ this paper will offer evidence from other states and countries around the world. Without analyzing firearm laws and crime statistics from other regions‚ a solution cannot be held plausible to reduce crime in Ohio. We must also disregard

Using 3D printers as production tools has become known in industry as “additive” manufacturing. The additive process requires less raw material and‚ because software drives 3D printers‚ each item can be made differently without costly retooling. The printers can also produce ready-made objects that require less assembly and things that traditional methods would struggle with—such as the glove pictured above‚ made by Within Technologies‚ a London company. It can be printed in nylon‚ stainless steel

Since I started the MSW program‚ stress has been no stranger and during my first semester I was introduced to mindfulness-based stress reduction (MBSR) in one of my classes. MBSR began over 30 years ago at the University of Massachusetts Medical School by Dr. Jon Kabat-Zinn (Noonan‚ 2014). MBSR was originally developed as an 8-week course designed to teach students’ basic relaxation and breathing strategies‚ along with mediation and simple yoga (Noonan‚ 2014). Till this day the course is being used

went to sleep‚ the emotions would send all the memories created during the day down to long-term memory. The emotions could then recall these memories whenever they needed them by requesting them to be sent up to headquarters. Drive-Reduction Theory Drive-Reduction Theory refers to an internal state of tension that motivates an organism to engage in activities that should reduce the tension. In the movie‚ Rylie was unhappy after her move to San Francisco. This creates an internal state of tension

An investigation to show how the rate of reaction between hydrochloric acid and sodium thiosulphate is affected by the concentration of the acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate‚ and record the amount of time taken for the cross to disappear through the solution from the top of the flask. Record this time and repeat this for different concentrations of hydrochloric acid. Fair Test The variables in
