    The correct answer is: D. 3H2 + N2 → 2NH3

    Ammonia (NH3) is a colourless gas with a characteristic pungent smell with wide use. Ammonia is a common nitrogenous waste, specially among aquatic organisms, and it is a precursor to food and fertilizers to terrestrial organisms. It is used as building block for the synthesis of many pharmaceutical products and cleaning products.

    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.
