packing efficiency calculations involving unit cell

(FCC arrangement) We have found that for a ccp arrangement We also know that, per unit cell in ccp arrangement has effectively 4 spheres. Therefore, Percentage efficiency ..

For cubic crystals of ionic compounds (NaCl, ZnS). The formula is the same except that now, Z is the Number of formula units present in one unit cell and M is Formula mass. The above equation involves five parameters. Knowing any four, the fifth can be ..

In photosynthesis, light energy is converted to chemical energy and carbon is fixed into organic compounds. Light energy is captured by the living world by means of pigments. The pigments involved in photosynthesis in eukaryotes include the chlorophyll and carotenoids. Light absorbed by t..

In lower organisms, there is no transport system as the cells are in touch with the surrounding medium. The transport is by the physical processes like diffusion, osmosis, etc. With the advancement in structure, the organisms have to evolve methods to transport nutrients and wastes. ..

Light Phase consists of photochemical reactions which are carried out by two different photo systems, PS-I and PS-II. In the thylakoids, chlorophyll and other molecules are packed into units called photo systems. Each photosystem unit contains from 250 to 400 molecules..
