Inert Gases Inert Gases and Characteristics • The inert gases are obtained by fractional distillation of air. • They are often used aboard chemical tankers and product carriers (smaller vessels). • Helium‚ Neon‚ Argon‚ Krypton‚ Xenon‚ Radon and are inert gases. • Duplet (Helium) or Octet • Full valence shell • • • • Weak interatomic force Very low melting and boiling points. Monatomic gases under standard conditions Helium has several unique qualities when compared with

‘The Land of the Rising Sun’; that is what the Japanese call the land in which they reside. It earned the name from the fact that if you were to gaze from China‚ a nation in which Japan derives an extremely large amount of its culture from‚ the sun appears to arise from the area where Japan lies. It is believed that the first Japanese inhabitants crossed over from China via an ancient land bridge that has since been lost to the sea due to continental drift‚ or they were simply Chinese fisherman who

Nobel gases are a group of six elements in group VIIIA of the periodic table; they are in the column farthest to the right. It is a collection of five elements: argon‚ helium‚ krypton‚ neon‚ radon‚ and xenon. Unlike most elements‚ the noble gases are monatomic‚ which means the element is a single atom instead of being in pairs or a combination. The atoms have stable configurations of electrons. In other words‚ under normal conditions they do not form compounds with other elements. They got there

Chapter 6 – Properties of gases lecture notes 1. Gas phase Gases have neither definite shape or volume 1) volume changes with pressure 2) volume changes with temperature 3) gases are miscible 4) gases are generally MUCH less dense than liquids 2. Atmospheric pressure 1 atm = 760 torr (mm of Hg) F= ma F = force m = mass a = acceleration P = F/A - ma/A P = pressure

based on my research‚ wind energy is the result of the sun’s energy interacting with the earth’s surfaces. It is also an ideal renewable energy source that is infinitely sustainable; pollution free; doesn’t use fuel; and doesn’t produce greenhouse gases‚ toxic or radioactive waste. This type of energy is considered a green power technology because it has minor impacts on the environment. When using wind to generate electricity we use machines known as turbines and this turbines use blades that are

Cathleen Ni Houlihan: Irish Nationalism In the early 1900s Ireland was conflicted with war. During this time period Yeats and Gregory wrote Cathleen Ni Houlihan‚ to send a message to the Irish people about serving one’s country. In his play Cathleen Ni Houlihan‚ Michael understands through Cathleen‚ a symbol of Ireland‚ the importance of sacrificing worldly needs in order to protect the motherland‚ and rises to become a hero. Yeats also shows that only devout devotion to one’s country

"Kingly Gases" What is chemistry? According to dictionary.com‚ the definition of chemistry- is the science that deals with the composition and properties of substances and various elementary forms of matter. Chemistry is everywhere. For example: in a kitchen‚ it is in everybody’s chemically treated water‚ or fruits grown with fertilizers and pesticides‚ or polymer material in the marble counter tops. Again‚ Chemistry is everywhere. If a person wanted to go deeper into chemistry‚ they probably would

Experiment #1 Date: September 13‚ 2011 Title: Diffusion in Gases I Aim: To observe the diffusion of bromine Apparatus and Materials: Glass tube‚ bromine‚ fume chamber Diagram: Procedure: -Liquid bromine was placed in a jar and covered Observations: When first placed in the jar the original color of bromine was red-brown. As it began to diffuse its color changed from dark brown to a lighter brown until it becomes a yellow-like orange color. As it was diffusing liquid bromine changes its state

Purpose: The purpose of this experiment was to test and observe the physical and chemical properties of gases‚ and to use these properties to identify these gases when they are encountered. Procedure: Create a data table similar to that in the lab assistant to record your observations. Gather the following lab equipment: Goggles‚ test tubes‚ 24 well plate‚ Gas assembly with copper and plastic tubing and a #00 stopper‚ short stem pipet‚ rubber stopper #00 with one hole and a pipet tip with
