You can reduce wind erosion by providing a protective plant cover for the soil.
The molecules or atoms that are formed by gain or loss of one or more valence electrons are said to be ions.
When atom loss one or more valence electrons, results in formation of cation whereas when atom gain one or more valence electrons, then formation of anion occurs. Cations carry positive charge and anions carry negative charge.
In general, cations are smaller than the neutral atoms from which they are formed and anions are larger than the neutral atoms.
As cations are smaller than the related neutral atoms because the valence electrons are lost which are farthest away from the nucleus. After that, taking more electrons distant from the cation results in reduction of radius of the ion.
Thus, aluminium cation consist of few electrons which results in fewer occupied energy levels by the electrons further results in reduction of radius i.e. smaller size.
Hence, given statement is true i.e. aluminium atom is larger than the aluminium cation as cation has fewer occupied energy levels.
Answer:
The answer to your question is: D. Fractional distillation
Explanation:
A. Column chromatography this method is use to separate mixtures base in its capacity to be absorbed.
B. Fractional crystallization this method use the solubility of solutes in a solvent.
C. Simple distillation is a method to separate 2 liquids based on the difference in their boiling points.
D. Fractional distillation is a method used to separate a mixture of liquids which have their boiling points very close.
E. Paper chromatography is a method to separate a mixture based on their different rate of migration on a paper.
Its probably becuase of the amount of minerals found in the ocean floor.Salt just so happens to be a major one.not only that,but the amount of salt that the human body emits while while outside,normally by bodies of water,it could also be that.
