Most fertilizers contain ammonia (NH3). Ammonia forms when hydrogen reacts with nitrogen. Which equation correctly represents the chemical reaction that forms ammonia?

The correct answer is: 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.
