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.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
