Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom

are prime examples of the implementation of gas laws. The physics are based on the simple principle that warm air rises in cooler air. Hot air has less mass per unit of volume. The relevant gas law in use is Charless Law‚ which is V1/T1=V2/T2. The law states that raising the temperature (T1) will also increase the volume (V2)‚ in order to keep the equation true. Generally‚ air is heated through the use of propane burners. When ignited‚ the volume of the gas increases but the balloon cannot expand much

Chemical Fertilizers vs. Organic Fertilizers INTRODUCTION Agriculture is the most primitive occupation of the people which mainly needs land to grow different crops for food and as raw materials for different industries. Industrial use of agriculture for supplying raw materials came much later. Originally land was used for agriculture to supply food for human beings by the use of organic manures particularly animal dung. At the beginning land was used in its natural form to grow food. Land contains

ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

Danielle Perkins September 9‚ 2013 AAPSC 603 Discussion Paper The Factors Affecting Greenhouse Gas Emission in the Livestock Industry People around the world have become very aware of the changes our world is going through on a constant basis. One of the biggest subjects people are talking about is global warming and how the human race is the number one cause of it. In more than one way this is unmistakably true. From the daily activities of driving gasoline powered cars to the simple necessity

The Effect of Sugar Type on Rate of Energy Production During Yeast Fermentation Sarah Sulon Biology Lab 111L Dr. Murray October 25 2010 Abstract The experiment was conducted to determine the impact different sugar types have on yeast fermentation. It was hypothesized that glucose‚ sucrose and fructose would all produce energy through yeast fermentation‚ but that sucrose would have the greatest rate of energy production. The carbon dioxide production was tracked in the fermentation of yeast
