Answer:

Crossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis.

Crossing over results in a new combination of genetic information for the cell for a specific trait.

Crossing over ensures that organisms are not identical from generation to generation.

Genetic recombination allows for a variation in genetic material that is passed through the generations.

Crossing over produces modern combinations of alleles. Not unused alleles but unused combinations which can result in modern phenotypes or expanded assortment of phenotypes. This way the there's expanded genotype/phenotype variety but the genuine qualities are still the same ones.

N2 + 3H2 → 2NH3 in this equation How many moles of NH3 can be made if 7.5 moles of H2 react with enough N2
Lena [83]

Answer:

5 moles of ammonia would be formed.

Explanation:

Given data:

Moles of NH₃ formed = ?

Moles of H₂ react = 7.5 mol

Solution:

Chemical equation:

N₂ + 3H₂       →    2NH₃

Now we will compare the moles of ammonia with hydrogen.

             H₂              :           NH₃

              3               :             2

             7.5             :          2/3×7.5 = 5

5 moles of ammonia would be formed from 7.5 moles of hydrogen.
