catalytic converters in the automobile can bind with the pollutants and reduce the waste materials that cause pollution. gasoline engines‚ catalytic converters are reliable and efficient at reducing pollution. They convert an estimated 90% of the hydrocarbons‚ carbon monoxide‚ and nitrogen oxides produced into less harmful compounds. However‚ catalytic converters are less efficient when used with diesel engines‚ which run colder than gasoline engines. Catalytic converters work best at higher temperatures

in defense. Consequently‚ while framing the Industrial Policy statement of 1948‚ the development of petroleum industry in the country was considered to be of utmost necessity. Until 1955‚ private oil companies mainly carried out exploration of hydrocarbon resources of India. In Assam‚ the Assam Oil Company was producing oil at Digboi (discovered in 1889) and the Oil India Ltd. (a 50% joint venture between Government of India and Burma Oil Company) was engaged in developing two newly discovered large

"Pollution affects two essential aspects of our planet: air and water. Although their pollutants are emitted in different ways‚ they both harm all living organisms. Air pollution is predominately emitted through the exhaust of motor vehicles and the combustion of fossil fuels‚ whereas water pollution is the result of industrial waste and environmental accidents. Our society knows that pollution is harmful and a serious problem for Earth but generally people don’t care. Nevertheless everybody needs

An oil spill can be defined as an accidental or deliberate dumping of oil or petroleum products into the ocean and its coastal waters‚ bays‚ and harbors‚ or onto land‚ or into rivers or lakes (Holum 1977). Between one and ten million metric tons (one metric ton is 1000 kilograms) of oil are put into the oceans every year. The oil is released‚ most often‚ in small yet consistent doses from tankers‚ industry‚ or on shore waste disposal (Boesh‚ Hersher‚ et al. 1974). Tanker spills cost the United

past few decades‚ adulteration of food has become one of the serious problems. Consumption of adulterated food causes serious diseases like cancer‚ diarrhea‚ asthma‚ ulcers‚ etc. Majority of fats‚ oils and butter are paraffin wax‚ castor oil and hydrocarbons. Red chilli powder is mixed with brick powder and pepper is mixed with dried papaya seeds. These adulterants can be easily identified by simple chemical tests.

The result in table 4 matches the hypothesis that the longer hydrocarbon chain stays in a molecule‚ that molecule will become less polar. This hypothesis sort of made sense‚ since hydrocarbon is a nonpolar molecule while the alcohol contains oxygen making it a polar molecule. The longer the chain‚ the less effective it will be to the polar side of the molecule. Methanol looked like an outlier because it doesn’t have that much hydrocarbon and in the first part of the experiment it was to mix with water
