in the combustion engines of vehicles and electrical power stations also releases large amount of carbon dioxide into the atmosphere. * Human activities such as open burning cause severe smog and haze. * Industrial plants and factories also pump large amount of carbon monoxide‚ oxides of nitrogen and sulphur dioxide into the atmosphere. * Both oxides of nitrogen and sulphur dioxide can combine with water vapour in the atmosphere to form nitric acid and sulphuric acid respectively.

The element I chose is Sulfur. Sulfur’s symbol is S‚ and it’s in the Chalcogen family. Sulfur has a lot of roles to play in our bodies. It’s also one of the abundant elements in our bodies with a mass percentage of 0.2. Sulfur’s atomic number is 16‚ and its Mass number is 32.066. In addition‚ Sulfur is a non-metal. Sulfur has multiple physical and chemical properties; one of the physical properties is that Sulfur is insoluble in water. A chemical property for Sulfur is that it’s a very reactive element

is released by volcanoes and in various industrial processes. Have you guys ever had the chance of being close to a volcano? I went to a geothermal park in New Zealand and once I came into the gate of the park‚ my nose is filled with the smell of sulfur‚ like the smell of rancid eggs. PPT 5 Here is a question. Have you ever noticed that the old things‚ such as pure white newspaper gradually become off-white? Or the stylish straw hat you got at last year become a little bit yellow which made

For many historians the effect of pollution on historical sites is a daily battle. Acid rain and smog eat into marble causing small holes in the stone. The Acropolis in Greece is one of main sites that is having this problem. All over the world buildings and historical sites are having problems with pollution and the growth of cities near the site. The Spinx is crumbling and through the centuries various repairs have been done to it‚ but that has only aided the damage from smog and traffic. The Roman

How do you keep carbon dioxide from escaping a carbonated drink when the drink’s container has been opened? When you open a carbonated beverage’s container‚ such as a soda can or bottle‚ you may hear a hissing sound from the opening as you do so. That is the sound of the carbon dioxide gas escaping from the sealed container through the new opening. When this happens‚ the process of the beverage losing its so-called "fizz" has already begun. However‚ there are several solutions to this issue. This

MONOLOGUE FOR AN ONION: AN ANALYSIS Cutting an onion breaks cells in its skin causing a reaction that results to the formation of volatile sulfur compound which‚ when mixed with tears coating our eyes‚ becomes sulfuric acid. This triggers the tear ducts to produce more tears to alleviate the imbalance in acidity the irritant has caused; the longer the eyes are exposed to the acid the greater the quantity of tears produced. Sue Kwock Kim uses this certain property of an onion to tackle a specific

beneath. This black crust is primarily composed of gypsum‚ a mineral that forms from the reaction between calcite‚ water‚ and sulfuric acid. Gypsum is soluble in water; although it can form anywhere on carbonate stone surfaces that are exposed to sulfur dioxide gas (SO2)‚ it is usually washed away. It remains only on protected surfaces that are not directly washed by the rain. Gypsum is white‚ but the crystals form networks that trap particles of dirt and pollutants‚ so the crust looks black. Eventually

INTRODUCTION Sulphuric Acid is an important chemical‚ which has large-scale industrial uses. Its major user is the phosphate fertilizer industry. Other important applications are in petroleum refining‚ steel pickling‚ rayon & staple fiber‚alum‚ explosives‚ detergents‚ plastics and fibers etc. Sulphuric Acid Industry is very old and has been continuously adopting the technological developments. It started with Lead Chamber process followed by contact rocess with Single Conversion Single Absorption

Sulfa drug. When scientists isolated the active part of the prontosil molecule they discovered how it and all sulfa drugs work. Sulfa drugs contain a sulfur atom that has six total bonds (shared electrons) and six electrons of its own; this breaks the octet rule which states that atoms try to acquire eight electrons in their outer shell (not 12). Sulfur (and phosphorus) is element 16 on the periodic table; its elections are far enough to pond relatively freely with other atoms but close enough to be

Air pollution is a major problem facing our environment today. This dilemma is harmful to every single living creature on this planet. How can we limit the causes of air pollution? There are industrial as well as residential causes of air pollution. How can we limit the effects of air pollution? We all know it affects the environment‚ but it also can affect us directly. Air pollution can be defined as impureness of the air. Air pollution is all around us. It might not be as clearly visible in
