CS gas

Lacing your boots Sweat was dripping down my face. I was readjusting my helmet for the last time as it broke earlier in the day. The trench almost looked like a vacation spot near the beach. The soft yellow light reflecting off the sand and the complete silence of the immediate area. My breath got shallow. I kept trying to practice perfect breathing but almost at the same time afraid that I would not hear a command. The sound of alternating radio beeps was inconsistent. Then out of nowhere, a man

The goals of the first assignment are to learn and execute proper document formatting, resource and data gathering, data analysis, and to demonstrate knowledge of plagiarism. In order to successfully complete the first assignment, I will complete a short series of tasks to help get me started. First, I read all supporting documentation on the formatting of the assignment. Then, I read through the assignment and found some information in the tasks that I had questions on. Knowing the assignments tasks

component of a mixture at a temperature above the temperature where the substance starts to degrade. As a homogeneous mixture is cooled while being exposed to a component in gaseous form, the partial pressures of the parts (hypothetical pressure of a gas if it had the same volume as the total volume at the same temperature) increases over time. Extraction can occur when the sum of the partial pressures is greater than the atmospheric pressure. Two qualitative tests are conducted in this lab: one with

The objective of this experiment is to see how safe bottled and tap water is to drink based on what is in the water; specifically the contaminants and the pH balance of the water. As well as if the temperature of the environment that the water is placed in affects the pH balance of the water along with if bacteria is grown due to the condition it is in. Water is one of the most important things in life, being as it is known as the universal solvent, and humans and many other animals need it to survive

In this investigation, we were required to design our own self-sustaining ecosystem, and monitor the changes in temperature and CO2 levels. We compared the outside temperature and CO2 levels, to those of our ecosystem. Self-sustaining ecosystems are in the process of being designed tested, so that one day humans will be able to survive and thrive on other planets, like Mars. The outcome of our ecosystem was a failure, like all other previous attempts. Our ecosystem was too hot and had too higher

Introduction: Melting point and Boling point are two fundamental physical properties that are commonly used to identify unknown compounds, to verify already known compounds, and to determine the purity of compounds.2 If the compound is a solid, the procedure for melting point determination is followed. However, if it is a liquid a boiling point technique must be performed, such as distillation or refluxing.2 The melting point determination consists of five major steps: obtain the sample and make

The complex and interesting optical properties can be shown clearly on Nanostructured metals the collective oscillations of the conduction electrons termed plasmons lead to most striking phenomenon encountered in these structures are resonances . Plasmon modes exist in a number of geometries and in various metals — most importantly in noble metals such as gold, copper and silver. Under certain circumstances plasmons are excited by light, which leads to strong light scattering and absorption and

1. Figure 1 shows the heating phases that occurred during the experiment. There is an exponential decrease in temperature as the depth of the water increases. Water has a high specific heat capacity which means that it can resist changes in temperature. This is coupled with the fact that solar radiation progressively loses its penetrative ability as the depth of the water increases. The light attenuation in lakes describes the decrease in actual light that can penetrate a water column as well as

Investigating the Effect of Temperature on the Permeability of Membranes The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents, for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the cell through facilitated diffusion the temperature must
