Experiment 9 Thin Layer Chromatography Experiment: 9 Title: Thin Layer Chromatography Introduction: Chemical analysis is conducted on specific analytes (specific substance of interest in a mixture)‚ however it is often found that these analytes must be separated for the chemical analysis to conduct their analysis. Chromatography is a set up of laboratory a technique that is used to separate a chemical mixture. This technique is very useful as it allows us to follow the course of

In this experiment we are going to describe stress and prove how can a prolonged exposition to it have a negative impact on memory. The definition of stress used in this experiment is: difficulty one suffers that causes worry‚ emotional tension or loss of concentration. The reason why this topic has been chosen is because stress is a part of nowadays‚ hectic society and it has a very noticeable effect on people’s performance‚ in either work or daily life. The outcome of this experiment could be

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

California Proposition 13 Name: Institution: California Proposition 13 What is proposition 13? Property taxes in California have been a controversial issue for very many years. In mid 1978‚ approximately ⅔ of voters in California passed proposition 13. Before it had been passed‚ property taxes increased almost annually according to the assessed value of the property. In the 1970s‚ there was a remarkable growth in the real estate market and the value of homes rapidly went up. Property values

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite
