Molecular orbital theory

Question

Question 1: Applying Molecular Orbital (MO) theory, determine the bond multiplicity and magnetic properties for the F₂ molecule. Compare its stability to that of the F₂⁺ species.

Question 2: Hydrogen and iodine react according to the equation:

H_2(g)  +  I_2(g) ↔ 2HI_(g)

a) Suppose 1.00 mole of H₂ and 2.00 moles of I₂ are placed in a 10.00-L vessel. How many moles of each substance are in the gaseous mixture when it comes to equilibrium at 458C? The equilibrium constant, Kc, at this temperature is 49.7.

b) How would the reaction be affected by pressure? 

Question 3: Balance the following redox reactions:

a) Cl₂ → Cl¯ + ClO3¯ (basic medium) 
b) MnO₂+ HNO₂ → Mn²⁺+  NO₃^¯ (acidic medium)

Question 4: Describe how would separate the following mixture of ions: Na⁺, Hg²⁺ and Ca²⁺.

Question 5: Orthoclase feldspar has the chemical formula KAlSi₃O₈, where the potassium is not covalently bonded. Name two cations that could replace the K⁺ ions in the structure.
