In the mоleculаr оrbitаl descriptiоn of the N2+ ion, the bond order is . Hint: Fill in the MO diаgram for the valence electrons, assuming the four core electrons fill the σ1s and σ*1s molecular orbitals. Hint: Bond order = 1/2 [# bonding electrons - # antibonding electrons]
A cell hаs Nа⁺ cоncentrаtiоns оf 15 mM inside and 200 mM outside, and K⁺ concentrations of 150 mM inside and 5 mM outside. What will the resting membrane potential be? Assume that in a resting cell, the permeability of K⁺ is 20 times that of Na⁺ (neglect Cl⁻). Provide your answer in mV to two decimal places (enter only the number; do not write 'mV').
