5 Solutions That Will Prevent High Bounce Rates On Your Hospital's Website Firms are taking advantage of the digital revolution world over. However, the health industry has been slow to take up the digital opportunity. Many others that have gone online are stuck in low traffic or high bounce rate. The inability to come up with innovative ways to get the patients to interact with the hospital website leads to several missed opportunities. A recent survey shows that more than sixty percent of the interviewed

CH 220C – Organic Chemistry Lab Experiment 13: Electrophilic Aromatic Substitution: Nitration of Bromobenzene and Relative Rates of Reaction Rodan Devega Introduction Electrophilic aromatic substitution (EAS) reactions involve the replacement of a hydrogen atom bonded to an aromatic compound by an electrophile. The rate and direction of the EAS reaction depends on the functional groups present on the aromatic compound. The purpose of this experiment was to synthesize bromonitrobenzene by reacting

5-di-tert-butyl-benzoquinone by dioxygen in dimethylformamide. The oxidation reaction was followed by measuring dioxygen uptake. The rate constant of oxidation reaction showed a linear dependence on catalyst concentration and saturation kinetics in both 3,5-di-tert-butylcatechol concentration and dioxygen pressure. The kinetic parameters have been determined using Michaelis-Menten approach. A mechanism has been suggested for the oxidation reaction. Keywords: Cobalt(II)porphyrin complex; oxidation; 3,5-di-tert-butyl-

this experiment was to determine the role of various chemicals in a reaction, to determine how concentration affects the rate of the reaction, and to determine how temperature affects the rate of the reaction.  Both concentration and temperature greatly affect the rate at which the reaction occurred, and changing the concentrations of the reactants or the temperature at which the reaction occurred changed how quickly the reaction took place. The scientific aim of this experiment was to determine which

Discussion: There are numerous ways of isolating and purifying a substance, and an investigation of the differences of each procedure were performed. In two different procedures, lead nitrate and potassium iodide were used to isolate and purify pure solid lead iodide, and the differences in the limiting reactant and solid lead iodide was observed. The amount of solid lead iodide was calculated by the measuring the mass of which the solid lead iodide was created in before and after the purification

On October 3, 2017, at eight in the morning, a few classmates and I decided to be deviant. We wanted to grab our classmate’s attention and see their reaction when three of us ripped posters off the wall in the classroom and that is when the learning theory (Warehime, Learning Theory, 2017) came in effect because one student talked into participating in the act. That was our deviant act for the day and to see the way our classmates reacted was quite shocking. Participating in this defiant act gave

purpose of the lab is to study the effect of a chemical reaction, on the change in mass. Procedure: 1.Place Alka-Seltzer tablet into bottle cap. 2.Pour approximately ⅓ of bottle volume of water into the Coca-Cola bottle. 3.Using a scale, mass the bottle with water and the cap with the tablet. 4.Combine the two reactants by inserting the tablet into the bottle and by quickly screwing the bottle cap onto the bottle. 5.After the reaction occurs, mass the newly dissolved solution. 6.Record

University of Amsterdam, he was appointed lecturer in theoretical and physical chemistry. He was the University of Amsterdam their Professor of Chemistry, Mineralogy, and Geology. While at the University of Amsterdam he conducted the studies of reaction rates, chemical equilibrium, chemical affinity, and osmotic pressures that helped found the discipline of physical chemistry. He held this position

Although the original function of HbHNL is to produce HCN from acetone cyanohydrins for plant defense purpose, its reversible reaction to produce enantiopure cyanohydrins makes it an industrial relevant enzyme (Fig. 1.6a). Besides acetone, it is also able to take a bigger substrate such as benzaldehyde and turn it into mandelonitrile with optical purity up to 99%.15 HbHNL is known to turn different aliphatic or aromatic aldehydes and methyl ketones into different cyanohydrins.15 Cyanohydrins are
