PHYSICAL CHANGE Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but cannot usually be used to separate compounds into chemical elements or simpler compounds.[1] Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance

CO2 Usage and Transportation: An evaluation of fuel consumption and emissions Introduction From this class I have come to understand the reach and reality of global warming. Every purchase I make has an impact regardless of how minute I feel it is. Many other consumers are faced with the same choices globally. It is those who consciously decide as an individual to purchase items with smaller carbon footprints that can make a difference as a whole. There is a broad spectrum of choices to be

6. Write 8y = 300 in its equivalent logarithmic form. log(base 8) 300 = y 7. Hurricanes are some of the largest storms on earth. They are very low pressure areas with diameters of over 500 miles. The barometric air pressure in inches of mercury at a distance of x miles from the eye of a severe hurricane is modeled by the formula f(x) = 0.48 ln (x + 1) + 27. (Source: A. Miller

pectin. 2/ The specific mechanism of Pectin in industry except Food industry. The mechanism of Pectin in mining industry: detoxification. In mining industries, the workers have to work in harsh environment that has many toxic cations like mercury, cadmium, lead, arsenic, etc. These cations enter the gastrointestinal tract and respiratory track and causes serious problems. Pectin is used in the detoxification of these cations and there by cures many diseases. Low methoxy pectin can be gel

Respiratory acidosis is abnormally high amounts of carbon dioxide gas dissolved in systemic arterial blood, above 45 mmHg (millimeter of mercury) and a deviation of pH away from the normal value of 7.4. Other causes include the presence of excessive carbon dioxide in inspired air (inhaled breath). Decreased alveolar ventilation (exhaled breath). Increased production of carbon dioxide by the body. Compensatory mechanism is compensation by the kidneys by conserving HCO3- (bicarbonate). Treatments are
