What is the overall charge of the compound frfr

As any molecular or ionic compound, 0 net charge, as a hypothetical diatomic cation, 2+

Explanation:

The question states that this is a compound, and any molecular or ionic compound would have a net charge of 0.

However, such a compound doesn't exist. Francium generally exists in nature having a 1+ charge in its cation form. Combining two francium ions would result in a species which is simply a diatomic ion but not a compound.

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.

there all right good
