none of these

same, different

Explanation:

Resonance structures have _same connectivity of atoms and __different distribution of electrons.

Resonance structures are obtained in molecules where the atomic positions are the same but the electrons joining the atoms keep on delocalising. Usually, none of the resonating structures can fit the molecule or ion. This implies that the real structure is the hybrid of all the possible structures.

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.

the millers tale is the answer.
