Atom economy is the percentage of the "wanted" product(s) in a reaction against all of the other calculated "waste" product(s). The formula for atom economy is as follows:
A.E.% = mass of wanted product/total mass of products x 100
Industrial reactions clearly use vast amounts of chemical reactants and therefore there is a large quantity of waste products. These large quantities of waste would have a high environmental impact and as a result much effort and energy is required to dispose of them in a "green" way this in turn costs. So those reactions with a low atom economy produce a high percentage of waste thus costing large sums to dispose of "correctly".
However, there are many more economical factors than simply disposing of the waste products. From an industrial point of view the chemicals used as reactants are bought and thus with a low atom economy large quantities of product are wasted along with the money that could have be gained if these chemicals had reacted into the desired product.
Therefore, industrial reactions with a high atom economy are economically important because, a high atom economy means a high amount of the desired product, as there is more of this, more can be sold generating a higher profit.
Sodium is produced more economically and thus is much lower cost than potassium. Sodium is also slightly easier to handle. Both are used extensively in industry but sodium metal is less reactive than potassium metal.
Chemical reactions occur because reactants are trying to become energetically more stable
Because the smoke of the industrial plants are emmiting heat thus becoming a thermal or heat pollution.
Because chemical reactions happen quicker in an increases temperature. So the more chemical reactions, the more chemical weathering
because of the chemical reactions of the abiotic and the digestive system in your body
because they are.
Because the Amazon Basin holds economically essential oil deposits.
Conifers are economically important because of their efficient production of lumber. Hardwoods are more difficult to process, too expensive, and the trees take a long time to replenish.
It's important because most of the people live on small farms and are only producing enough food for their families unlike industrial countries with larger farms made to produce food for many people.
It doesn't. Catalysts merely speed reactions along, they do not make them happen - that is the definition of a catalyst. Industrially, catalysts are important in making chemical reactions economically fast.
Economically mainly because they disturb important trade routes.
because they flow north to south
because
Because it provide's medium for many chemical reactions.
What they are worth, their location, how accessible they are, their uses (many or few) Eg, sunlight is economically important because it not only has many uses, but can be found everywhere across the Earth
Its important to view reactions, because only about 70-80% of communication is verbal, meaning that you are gong to be missing out on a large part of communication if you aren't paying attention to peoples facial and bodily reactions.
Because drug abuse can lead to many problems economically, maritally, occupationally, and physically.
