Coulomb’s Law 1. Objective - To study the validity of Coulomb’s law on a simple electroscope. This will be split into two parts; first measuring the the force as a function of distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges

Mustard Gas During World War I LOST was the original name for mustard gas‚ it was named after Lommel and Steinkopf. They were the first people who proposed this gas to the military to use as a weapon in 1916. Although mustard gas could possibly been developed as early as 1822 by a French chemist‚ Cesar-Mansuete Desperetez. Thirty-two years later Alfred Riche repeated this reaction of the sulfur dichloride and ethylene‚ but both Riche and Desperetez did not note any harsh properties. In 1860‚

is * Sulfur mustard is a type of chemical warfare agent. These kinds of agents are called vesicants or blistering agents‚ because they cause blistering of the skin and mucous membranes on contact. * Sulfur mustard is also known as “mustard gas or mustard agent‚” or by the military designations H‚ HD‚ and HT. * Sulfur mustard sometimes smells like garlic‚ onions‚ or mustard and sometimes has no odor. It can be a vapor (the gaseous form of a liquid)‚ an oily-textured liquid‚ or a solid

Abstract: The topic of this research involved the occurrence of genetic transformation in bacteria (E. Coli). More specifically‚ a previously prepared pGLO plasmid--which consisted of the gene to be cloned--was used to transform non-pathogenic bacteria. The pGLO plasmid contained a gene for the Green Fluorescent Protein (GFP) from a bioluminescent jellyfish and a gene for resistance to ampicillin‚ an antibiotic. Essentially‚ we wanted to determine the conditions of the bacteria that would glow.

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

Fluctuating Gas Prices Kyle Bonzelaar Davenport University Gas prices have been on a rapid rise the last few years and not many people are happy with it. It limits those on a budget for how much they can do and how much they are willing to drive. Lately‚ gas prices have been fluctuating in price and going up but are more recently going back down‚ which gives people a little more flexibility at times in their schedule. It lets people do things such as travel and more‚ that they were not able
