producing another action potential (Stillman‚ 2005). In this lab‚ compound action potentials (CAPs) will be measured from an isolated sciatic nerve from a cane toad‚ Bufo marinus. Compound action potentials are the total sum of action potentials from the multitude of neurons that compose a nerve (Stillman‚ 2005).

Analysis of Alum‚ AlK(SO₄)₂ •12H₂O Purpose The purpose of the experiment is to confirm whether the compound is Alum. Introduction Percent composition is defined as part divided by whole multiplied by 100. Water of hydrogen is defined as the amount of water produced into a molecule prepared in an aqueous solution. Molecular formula indicates the actual numbers and type of atoms in a molecule (notes). Procedure The procedure in this experiment is to determine melting point and mole ratio of

Synthetic Organic Compounds Synthetic organic compounds are a relatively new discovery in the field of chemistry but have had a major impact on the world. These compounds differ from organic compounds as they are manmade. Synthetic organic compounds have been damaging people and the environment since they were created. Synthetic compounds such as chemical pesticides‚ herbicides and fertilizers have been beneficial to food production and

Discussion for Experiment 1 (Basic Laboratory Operations and Identification of a compound : Chemical Properties) In the first experiment‚ the precision of instrument was studied by measuring the mass of water for several times. The result shows that the mass measurement of the balance is precise since the masses of water in six trials are somewhat close. The reason that the masses of water in each trial are not identical may come from the high sensitivity of the balance that keep fluctuating due

Introduction “The history of all hitherto existing society is the history of class struggles.” (Tucker‚ 1978). These words began one of the most famous pieces Karl Marx ever wrote‚ The Communist Manifesto. In this work‚ he railed against what he perceived to be the evils of capitalism and called upon the workers around the world to unite to bring an end to this exploitative system once and for all. Communism was to rise and free all people from the shackles of the bourgeoisie and allow them to go

There are thousands of compounds which have been discovered‚ and are yet to be discovered‚ with all these possible combinations it is necessary to provide order through a systematic naming system. This naming system‚ aside from organization also provides the reader with information about the given element. There are different kinds of compounds‚ ionic‚ covalent‚ and acidic and over all of this the atoms making up the compounds are either binary or polyatomic. The simplest compounds to name are binary

We underwent two different reaction schemes using Dipotassium phosphate (K2HPO4) and Potassium hydroxide (KOH) to isolate the compounds of pure Acetylsalicylic Acid/Aspirin and N-(4-hydroxyphenyl) Ethanimidate/Acetaminophen respectively from Excedrin. The first reaction scheme to undergo acid-base organic extraction was to isolate the most acidic compound in Excedrin with a weak base‚ K2HPO4. We isolated the aspirin using aqueous base extraction‚ with Dipotassium phosphate then treated with HCl

The Communist Manifesto‚ published in 1848 after commission by the Communist League‚ was a revolutionary political manuscript that served to both outline the goals of Communism and articulate beliefs that would later define Marxism. Karl Marx and Friedrich Engels‚ two German philosophers and political theorists‚ worked together to create a criticism of the class struggles and emerging capitalist economy produced by the Industrial Revolution. By addressing the increasing wealth gap between the bourgeoisie
