Answer:
an isotope consists of two or more forms of the same elements that contains equal number of protons but different number of neutrons in their nuclei but differ in relative atomic mass but not in chemical properties
The percentage of soil components of the soil is: inorganic components
-soil particles
-mineral elements = 45%
-water or moisture= 25%
- air= 25%
organic components
-humus or decayed organic matter= 5%
-living organisms
We have that the correct wedge and dash conformation for the following Newman projection is
IV
From the Diagrams above
Two CH_3 groups points on opposite sides in plane
Two Br are on same side of plane
Two H also on same side of the plane so the plausible structure is IV
Therefore
The Correct option is IV
