problem 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.

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

H2(g)  +  I2(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? 

problem 3: Balance the following redox reactions:

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

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

problem 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.
