Wittig reaction

interested people and that is what keeps those television shows running. The key to getting and creating any chemical reaction that glows is just a few chemicals at the right temperature and a few simple substances that can transform a simple concoction into an eerie looking splotch of blood or human fluid. Chemiluminescence is the generation of light through a chemical reaction and it can be emitted or seen in ultraviolet, visible or infrared lights. Chemiluminescence is common and even found

(proteins and RNA molecules) that performs like a catalysts and assist in intricate reactions that can happen anytime in life. Enzymes accelerate the rate of all the chemical reactions that happen in cells. Enzymes are very important by the fact that they help in the human body by helping out with digestion and with your metabolism. Enzymes are choosy catalysts and this means that they only speed up certain reactions. The elements that can affect and not make the enzyme function properly is when there’s

Discussion: As only 2 balloons expanded in size, the results did not provide solid evidence to completely support the hypothesis of the practical. Having said that, the magnesium reaction time clarified its high metal reactivity as it expanded to its optimal circumference in the 30 seconds provided. Similarly, copper did not react at all as expected due to its low metal reactivity. However, between the maximum and minimum metals, in terms of reactivity, aluminium, zinc and iron showed no sign of

Aldol In this preparative lab, an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its

centred round global processing, the other around local processing, where there reaction times were recorded using a computer program and imputed into a data worksheet. Results indicated that, as predicted, global processing occurred at a faster rate than local processing. It was concluded that global features were

the rate of reaction also increases. This means that there are more collisions between the solid and liquid.) * Amount of tap water H2O used, i.e. volume (ml). * Amount of Alka-Seltzer tablets used, i.e. quantity of tablets. (one is used) *

Amount of Heat Produced When Magnesium Reacts with Sulphuric Acid When energy in the form of heat is given out of a reaction it is an exothermic reaction. Exothermic reactions usually need activation energy, the energy to break the bonds in the chemicals and to start the reaction. Once the bonds are broken new stronger bonds are formed. In an exothermic reaction energy in the form so heat is given out to the surrounding when the products are formed. Therefore there is an

I. Introduction Since the last decade of nineteenth century, there have been many experiments and approaches that were conducted to analyze which group men or women had a faster response reaction. Those experiments were about human response time which is the time needed to perceive, evaluate and respond to a particular question, or to identify the object, color. Sometimes, the response time also shows how smart people are, or how much information and knowledge they have. Franciscus Donders

While researching the greatest chemists that have ever lived, I could not help but notice one who was missing from the list. Boyle, Mendeleev, and Lavoisier were on everyone’s list; and rightfully so, but I believe that people overlook the outstanding work of Henry Louis Le Chatelier. Le Chatelier studied chemistry extensively in school and made great discoveries as a teacher of the science at colleges in France. He is most known for the principle named after him: Le Chatelier’s Principle, which

The Effect of Temperature on Anaerobic Respiration of Yeast We wanted to find the effect of temperature on anaerobic respiration of yeast. We investigated how a mixture of yeast, water, sugar, and flour were affected. Diagram ======= Apparatus ========= 1g of yeast 0.5g of sugar 10g of flour 6 measuring cylinders - to put the sachets in and the 20cm3 of water Measuring cylinders to measure the water Thermometers - to keep
