air gas mid america

Natural Gas - It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphide. Its gre..

Take two gas jars 'A' and 'B'. Fill jar 'A' with air and jar 'B' with dry hydrogen chloride gas. Invert 'B' over 'A' as shown in figure 5.4...

Air Pollution - Humans can only live about five minutes without air. Dry air is generally a homogeneous mixture (solution) of nitrogen gas (78%), oxygen gas (21%), and traces of other gases. Some of the other gases are waste products of human activi..

Dry Air - We know that there is water vapour in air. In other words, air contains moisture and so it is wet. This quality of wetness is referred to as humidity. For our physical comfort, humidity should not be too high or too low. Usually when the atmospheric temperatu..

. Ozone absorbs the ultraviolet radiation and while doing so breaks down into nascent oxygen (O) and oxygen gas O 2..

Composition of LPG - Butane with small quantities of ethane and propane. These gases can be liquified under pressure and bottled in cylinders. By itself LPG is odourless. On leakage, it is toxic if inhaled. It also forms an explosive mixture with air. LPG can be hazardous if handled carel..

In soda water bottles, the gaseous carbon dioxide exists in equilibrium with the carbon dioxide dissolved in water. When the soda water bottle is opened, the carbon dioxide dissolved in it escapes out rapidly with fizz. This is because, the soda bottles are sealed after adding carbon dioxide g..

> In exceptional cases, where oxygen is not needed at all for burning there is a subtle difference between the terms combustion and burning. Combustion requires oxygen gas either from the air or that which is released from chemicals used in a reaction. When a chemical reaction t..

a) Checking the air pollution by strict imposition of laws on factories. b) Reducing vehicular traffic and encouraging public transport vehicles than individual vehicles. c) Use of unleaded petrol. d) Regular check of exhaust gases from vehicles to declare their status in respect of poll..

(Nitrogen becomes liquid at -196 o C). Liquid air is then led into a chamber, and allowed to warm up, by absorbing heat from the atmosphere. The boiling point of nitrogen is -196 o C; when this temperature is reached, nitrogen starts boiling and the vapours (gas) is collected an..
