I need to know how to do this but if you could just answer it it's fine​

im not entirely sure what needs to be done but the 2NH3 is the product and the other half is the reactants .

if any elements are added to others it is the reactants

this is a breakdown of a compound because the arrow always indicates the direction of the reaction .

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.

b. is the answer hoped i
