greenhouse effect in is the entrapment of the sun’s heat energy in the earth’s atmosphere. Greenhouse gases such as carbon dioxide‚ water vapor‚ methane‚ and nitrous oxides are all gases that contribute to this phenomenon. Carbon dioxide is the most abundant greenhouse gas while water vapor the least harmful gas makes up less than one percent of the gases in the atmosphere. These greenhouse gases are produced naturally by the earth for example carbon dioxide‚ and methane is produced from the waste

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

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

events like super-storm Sandy continue to increase in their frequency and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’. The ‘greenhouse effect’ results from greenhouse gases such as carbon dioxide rising into the atmosphere‚ trapping infrared radiation from the sun‚ and emitting ultraviolet radiation that can puncture the earth’s stratospheric ozone layer. A healthy ozone layer should prevent this from happening‚ but the
Premium Greenhouse gas Oxygen Carbon dioxide
Greenhouse gases Carbon dioxide is a colourless‚ odourless gas that makes up .04 percent of the earth’s atmosphere. It’s released by the breakdown of organic materials‚ by animals when they respire‚ and by the burning of fossil fuels. Carbon dioxide isn’t toxic—after all‚ we exhale it with every breath and use it to make our drinks fizzy. However‚ carbon dioxide is considered a pollutant because‚ as a greenhouse (heat-trapping) gas‚ it’s a significant contributor to global warming. In the last 150

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

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

Experiment 4: Behavior of Gases Introduction: In this experiment‚ the problem trying to be solved is what gas laws are being used when the pressure‚ temperature‚ and volume are being measured. The three gas laws are Boyle’s Law‚ Charle’s Law‚ and Gay-Lussac’s Law. The Boyle’s Law is when volume and pressure are being compared. Pressure and volume are inversely proportional‚ because when pressure goes up‚ volume goes down. The Charle’s Law is when volume and temperature are compared. Volume and

Experiment 2 Behavior of Gases PURPOSE This experiment has two parts. The purpose of part A of the experiment is to determine the atomic mass of a metallic element whereas the purpose of part B of the experiment is to determine the rate of diffusion of both gases hydrogen chloride and ammonia by measuring the distances travelled by the two gases in the same time period. For part A the reaction of the metal with the aqueous acid is as follows: M(s) + n H3O+ -----> M+n(aq) + n/2 H2(g) +
