What happens when the compound nacl is formed?

a. sodium transfers an electron to chlorine.
b. sodium receives two electrons from chlorine.
c. sodium forms an ion with −1 charge and chlorine forms an ion with +1 charge.
d. sodium forms an ion with +2 charge and chlorine forms an ion with −2 charge

A

Explanation:

This kind of bond is known as an ionic bond and is based on electrostatic forces between two charged molecules/atoms. To achieve stable configuration, sodium (2.8.1) transfers its valence electron to chlorine that also needs one electron to achieve stable configuration (2.8.8), and combine in an ionic bond.

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.
