Calculate the empirical formula for each of the following stimulants based on their elemental mass percent composition. adenine (a nucleobase (a purine derivative) with a variety of roles in biochemistry): C 44.44%, H 3.73%, N 51.83%

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
