iron is extracted from its oxide ore called Hematite. Many things are produced in the extracting or iron from iron ore in a blast furnace. The iron ore is reacted with carbon and oxygen in the furnace to produce carbon dioxide and iron metal. Carbon monoxide is also produced so that it can react with the iron ore to produce the iron. At the end‚ there is left the molten iron and the slag. The top of the furnace is filled up with the iron ore‚ coke (made by heating coal) and limestone. The coke‚ iron

Cigarette smoking kills nearly 430‚000 people every year‚ making it more lethal than car accidents and drug overdoses just to name a few. A smoker’s life expectancy is reduced by 15 to 25 years and is the single most preventable cause of death. With lung cancer being a primary result of cigarette smoking‚ there are also a wide array of other lung problems that occur as a result of smoking. Cigarettes contain 4000 chemicals‚ most of them are toxic. These ingredients affect everything from proper

Petrol and diesel engine motor vehicles emit a wide variety of pollutants‚ principally carbon monoxide (CO)‚ oxides of nitrogen (NOx)‚ volatile organic compounds (VOCs) and particulates‚ which have an increasing impact on air quality. In addition‚ photochemical reactions resulting from the action of sunlight on nitrogen dioxide and volatile organic

COMMON AIR POLLUTANTS Some of the most common air pollutants can be classified as ground level Ozone‚ Particulate matter‚ Carbon monoxide‚ Nitrogen oxides‚ Sulphur oxides and Lead. Ground level Ozone – these are formed by photochemical (in the presence of sunlight) reactions in the atmosphere between oxides of nitrogen (NOx) and volatile organic compounds. Some sources

Chemistry is the branch of science that deals with the structure of organic and inorganic matter( any substance or organism which has a mass and occupies space)‚ its properties and reactions; however chemistry is primarily the study of reactions that any given substance takes on when interacting with another substance. Chemistry is the main incentive for the life that we live today; it has provided modern society with facilities that make our day to day lives easier. Predominantly chemistry has allowed

Know how photochemical smog is produced Hydrocarbons‚ carbon monoxide from vehicle exhausts are irradiated by sunlight in the presence of oxygen gas. The resulting reactions produce a potentially dangerous mixture‚ including other nitrogen oxides‚ ozone‚ and irritating organic compounds‚ as well as carbon dioxide and

The experiment consists of 5 steps—Inoculation‚ fermentation‚ cell lysis‚ inclusion body solubilization‚ and peptide purification. In the first two steps‚ E coli with Snake 6 peptides is cultivated. Ultraviolet–visible spectroscopy (UV-vis) is used to quantify bacteria through detection of their optical density (O.D.). After reaching a certain concentration in the fermentation batch‚ inclusion bodies (IBs) are extracted from these E coli by adding Bugbuster lysis solution and lysozyme. Polyacrylamide

Incomplete combustion releases a toxic compound called carbon monoxide in to atmosphere. Natural process may be dangerous at times but not always.
