Gas exchange is the movement of respiratory gases across a membrane. It is the delivery of oxygen to the body‚ and the elimination of carbon dioxide from the body .The reason why gas exchange takes place because oxygen is one of the most essential requirements of life‚ without which organisms on Earth would not survive. Living organisms generate energy from food through the process of respiration. This allows humans and other organisms to perform their daily tasks. Oxygen is used in mitochondria

only did poisonous gas change the experiences of war‚ but also the type of warfare. Instead of riding around on horses freely‚ soldiers had to use protection in order to evade the deadly chemicals. So‚ quickly‚ both sides developed gas masks. At first‚ soldiers held chemically treated cotton pads over their noses and mouths. Later they wore fabric face masks soaked in chemicals‚ and finally soldiers on both sides wore respirators with charcoal filters.("Technology.") These gas masks were the new

Greenhouse gas emission What is greenhouse gas? A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. Many greenhouse gases occur naturally‚ such as water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and ozone. Others such ashydrofluorocarbons (HFCs)‚perfluorocarbons (PFCs)‚ andsulfur hexafluoride (SF6) result only from human industrial processes. Greenhouse gases act like a blanket around Earth‚ trapping energy in the atmosphere and causing

The purpose of this lab was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the

Engineering Workshop 1 Exhaust Gas Treatment Index of contents Introduction Waste gas with harmful traces of gas must be burned in an afterburner. To destroy the harmful traces the temperature after the burner must achieve 900°C. The preheater can`t resist a temperature of 700°C. Therefore quench water in a mixer will be used to protect the heat exchanger. The waste gas has the following properties: Waste gas composition: Mole fraction(= 0‚9890
