Lithium metal reacts with nitrogen gas to form lithium nitride. identify the balanced reaction that describes this process. a. li + n lin b. li + n_2 lin_2 c. 2li + n_2 li_2n_2 d. 6li + n_2 2li_2n e. 2li + n_2 2lin 64. which of the elements listed below is most likely to exhibit an expanded octet in its compounds? a. o, p b. s, p c. na, k d. c, s e. n, s

Balanced equation:

64. option (B) is correct.

Explanation:

Lithium nitride has the molecular formula: . It consists of and ions.

Reaction:

Balance Li:

Balance N:

Balanced equation:

Elements having energetically available vacant orbitals are likely to expand octet as they can accommodate more electrons in those vacant orbitals by forming bonds.

Both S and P have vacant energetically available 3p orbitals which make them prone to expand their octet.

So, option (B) is correct.
