fractional amounts

What would you call different fractions that represent the same amount? => like fractions or equivalent fractions or unlike fractions or unequal fractions..

This method is used to separate two or more solutes, by making use of their difference in solubility. If we want to separate potassium nitrate from a mixture that contains about 80 g of potassium nitrate and 20 g of sodium chloride. We will dissolve this mixture in about 100 g of water and then hea..

Crude oil or petroleum pumped out of an oil well, is a viscous and complex mixture of several hydrocarbons and small amounts of other compounds. It is not useful in this state. The 'refining of (crude) petroleum' involves the process of fractional distillation, whereby petroleu..

Uses of Hydrogen - In many electrolysis reactions hydrogen is an important by-product. Enormous quantities of hydrogen are used in the manufacture of ammonia and in the synthesis of methyl alcohol. The hydrogenation of oils to produce edible fats, of coal to form synthetic petroleum, and of petrole..

Langmuir ,in 1915, obtained atomic hydrogen by dissociating on a hot filament of tungsten or platinum. The dissociation of molecular hydrogen is an endothermic process. The atomic hydrogen is stable only for a fraction of a second and immediately reverts back to its molecular form, lib..

The amount of all the noble gases put together (Helium, Neon, Argon, Krypton, Xenon and radon) is extremely low in air. These form only 0.94% of the volume of air and as such can be treated as negligible. These gases were found chemically inert (i.e. did not mix with other elements nor we..

. We call it an equation of state even when we do not know the actual equation. Here's a simple (though approximate) equation of state for a solid material. The temperature coefficient of volume expansion b is the fractional volume change per unit temperature change, and the compressibili..

Water - In the Earth's biosphere, water is essential to all forms of life. Interestingly, it is also the biospheres most abundant compound and a unique substance from the chemical point of view. About 75% of the Earth's surface consists of water. Water is present as either (a) Solid - ice, snow etc..

Carbon-14 is unstable and decays by beta emissions to nitrogen. Because of the constant production of carbon-14 and its radioactive decay, a small fractional abundance of carbon-14 is maintained in the atmosphere. Living plants, which use carbon dioxide from the atmosphere, also maintain ..

Construction - A photographic camera consists of a converging lens system at least one end of a box and a light sensitive film at the other end, a focusing device for adjusting the distance of the lens from the film and an exposure arrangement which provides the correct exposure. The object is plac..
