Introduction The scrap metal trade is a very controversial topic in Jamaica in recent times. Outside of registered dealers/traders‚ the industry has garnered interests from many others as it has become a way of life for providing quick income for households. Although the trade started out as a livelihood for these persons the paradigm has shifted and now stems more negatives than positives as unscrupulous persons has used it as an avenue to participate in illegal activities that resulted in the

Conclusion: The purpose of this lab was to synthesize and purify aspirin. The theoretical yield was calculated to 3.766g. The actual yield of pure aspirin was 2.863g with a yield of 76%. The percent yield indicates that our synthesis was a success but the yield is low and indicates that some of the aspirin was lost during synthesis. Some reasons for loss can result from human error such as loosing product from sticking on the spatula and the Buchner funnel and several weighings. Also‚ when transferring

Analyzing electrolytes I. Introduction Ionic substances form when a metal reacts with a non-metal. They contain charged particles called ions. Those ionic substances are broken down by electrolysis. Electrolysis is the breakdown of a substance by electricity‚ and it only happens in liquids. The liquids that can be electrolyzed are called electrolytes. When said electrolyzed‚ means that the compounds in solutions are broken down when they conduct electricity. Its necessary the use of electrodes

Dylan McFarland 9/15/14 Honors Chemistry Richardson Lab: Measuring the Density of Pennies Pre-Lab Questions: 1. The equation that relates density‚ mass‚ and volume is: density = mass / volume. 2. All substances have unique densities‚ so if you are able to find the density of a substance‚ you can properly identify it. 3. We measure irregular-shaped objects with the use of water displacement because it would be nearly impossible to get the exact measurements

Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature‚ some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However‚ the excited configuration is unstable‚ and the electrons must return back to their positions in the lower energy level. As they return‚ the energy that was previously absorbed is now emitted

Atom Bonding Lab Introduction: Atoms bond in covalent bonds and ionic bonds. A covalent bond is when atoms share electrons in order to gain stability with each other (Larsen). To have stability which each other‚ the atoms share electrons so that their outer electron shell is equal. Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions (Larsen‚ 2010). Element that have a positive ion are able to bond

Timothy Johns Christian Howard Wan Huang 10/18/12 Flame Test Lab Introduction Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If
