be used in order to determine the reaction stoichiometry Magnesium is used to react with hydrochloric acid in order to produce hydrogen gas. One of the purposes of this experiment is to determine X in the equation below The mass of the magnesium used is measured before the use in the experiment via an analytical balance. The known amount of magnesium is then reacted with excess hydrochloric acid which causes the magnesium to be the limiting agent in this particular reaction. The amount of HCl used

I believe in determination‚ determination is something that everyone should have. I’m an athlete and I think that every athlete should have some sort of determination. Determination is having your mind set on something and fulling that to the best of your ability. Every person should set goals in their life and to be able to accomplish those goals you need to be determined. This year I ran cross country. I hate running but I was determined not to give up cross country just because I hate running

Slippery slope is an informal fallacy of weak induction. It draws a conclusion from events of an exaggerated and improbable chain reaction. The following DIRECTV commercial shows a clear example of a fallacy of slippery slope: “When you wait forever for the cable guy‚ you get bored. When you get bored‚ you start staring out windows. When you start staring out windows‚ you see things you shouldn’t see. When you see things you shouldn’t see‚ you need to vanish. When you need to vanish‚ you fake your

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

Recrystallization of Benzoic Acid Objective To purify benzoic acid by recrystallization and gain experience with a basic organic laboratory techniques. Background Products of chemical reactions are often contaminated with impurities. One method for purifying chemicals‚ recrystallization‚ takes advantage of the differences in the solubilities of the desired products and the impurities and the tendency for the slow formation of crystals to exclude impurities from the crystalline solid.

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental level‚

English Constant Gardner Directed by Fernando The Film ‘The Constant Gardener’ Directed by Fernando Meircelles‚ Is fill confusion‚ entertainment and love. I thought the film was very good in the techniques the director used‚ but was hard to get my head around. ‘The Constant Gardner’ would be thought to be about gardening‚ but it’s just based around it. The concept of gardening is the story line of the movie. Two main characters Tessa and Justin are in love‚ but don’t know each other as well

Writing Assignment #2 27 April 2011 Death Constant Beyond Love Gabriel Garcia Marquez’s short story‚ “Death Constant Beyond Love” depicts the vulnerability and helplessness of a human when dealing with two of the most enigmatic parts of life. The background of corruption‚ poverty‚ and the political campaign become rather insignificant to the broader themes of love and death. Marquez expresses the confusion‚ power and diversity that come with the feeling of love and how ever changing it can be
