Patel Chem 101 10-13-09 Introduction The objective of this lab was to show how stoichiometry is applied to a specific chemical reaction. Stoichiometry is pretty much the math behind chemistry. Doing stoichiometry can calculate masses‚ moles‚ and percents with a chemical equation. The use of stoichiometry is how we were able to find the limiting reagent in this lab. A limiting reagent is the chemical that will be used up first. Many calculations had to be made throughout this lab. Some of

In the “Crush the Can” lab‚ we took an aluminum can‚ heated up some water in it‚ and turned it upside down into a tub of ice-cold water‚ crushing it with pressure. The movement of gas particles was a crucial component of this experiment. After the can was placed onto the hot plate‚ as the water heated up‚ the gas particles inside of the can started to move faster due to the relationship between temperature and the average kinetic energy‚ or average motion energy‚ of the gas particles. As the temperature

What Does The Evidence Reveal About The Death Of Otzi The Iceman? Advances in technology and scientific method over the last 25 years have provided new evidence which disproves the original theory that Otzi‚ the iceman‚ may have fallen‚ injured himself and died from hyperthermia. High resolution CT scanning as well as new scientific techniques which allow for the analysis of blood‚ tissue and DNA have resulted in entirely different evidence-based theories. Evidence now suggests that Otzi died violently

Environmental Systems Bio-cylinder Lab Report Planning: The question that we‚ as a class‚ were trying to answer was: How long can the organisms survive within a sample-closed ecosystem? To answer this three separate classes had the opportunity to create their own bio-cylinders‚ place a specified number of organisms‚ seal it‚ and observe the cylinder for however long the organisms were able to survive. Each class made small modifications to the number of fish and snails that placed within the

In the BIO 14 Lab‚ the organismal system used for the last of three labs this semester is the Mimosa pudica plant. In these three weeks the stimulus-response of these plants will used to conduct experiments on the phenotypic plasticity of Mimosa pudica. Phenotypic plasticity is the ability of an organism to change its phenotypic traits in response to changes in the environment. And while very beneficial in some ways such as by allowing organisms to adapt to a changing environment quickly‚ it also

Abstract The basic principle of Mendelian inheritance was studied using the fruit fly‚ Drosophila Melanogaster. A Cinnabar Brown female was crossed with Wild Type male. The flies were mated in a jar containing a nutrient medium and then placed in an incubator. The experiment was conducted over a period of 5 weeks. Cinnabar (cn) and brown (bw) are two loci in Drosophila with recessive eye colour mutations. Mutations in cn cause a bright red eye and mutations in bw cause a brown eye. Double mutants

Darwin’s concept of evolution was very influential in further developing both scientific and social theories. It fueled several perspectives about the future and current state of society at the time. Charlotte Gilman‚ for example‚ used Darwinian evolution to challenge the future of women’s roles in society in Women and Economics. Veblen’s The Theory of The Leisure Class used evolutionary thought to criticize society’s atavism to a barbaric past. Freud‚ in his novel Civilization and its Discontents
