Most fertilizers contain ammonia (nh3). ammonia forms when hydrogen reacts with nitrogen. which equation correctly represents the chemical reaction that forms ammonia? a.  3h2  + n2  → nh3  b.  h2  + n2  → 2nh3c.  h2  + n2  → nh3d.  3h2  + n2  → 2nh3

Answer

            The correct option is D.

Explanation with reason

            According to balance chemical equation

A. 3H2 + N2 → NH3

                              in the above reaction there are 6 mole of hydrogen atom and 2 mole of nitrogen atom on reactant side, one mole of nitrogen atom and 3 mole of hydrogen atom on product side. This is not a balance chemical equation.

B. H2 + N2 → 2NH3

                           There are 2 mole of hydrogen atom and 2 mole of nitrogen atom on reactant side and 2 mole of nitrogen and 6 mole of hydrogen atom on product side. This is not a balance chemical equation.

C. H2 + N2 → NH3

                           There are 2 mole of hydrogen as well as nitrogen atom on reactant side and i mole of nitrogen and 3 mole of hydrogen atom on product side. so, this is also not a balance chemical equation.

D. 3H2 + N2 → 2NH3

                               There are 6 mole of hydrogen atom and 2 mole of nitrogen atom on both side. So this is a balance chemical equation.

Conclusion

                   It is concluded from above discussion that D equation correctly represents the chemical reaction that form ammonia.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
