Choose the term that best describes all members of this series of elements V, Cr, Fe, Co, Ni

The reaction below has a Kc value of 61. What is the value of Kp for this reaction at 500 K? N2(g) + 3H2 (g) ⇌ 2NH3 (g) Report your answer with 3 significant figures

What is the electronic geometry and bond angles for NH3? Hint: Questions asks for ELECTRONIC geometry (NOT the molecular geometry): Electronic geometry is best viewed as the hybridization: number of areas of electrons (not as bonds and lone pairs)
