Please help me with nos 2 and 3 thank you

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.

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

they are both synthetic elements

explanation:

d

there is none because earth is stationary and flat.
