Saturated sodium chloride. describe what happens when 12 M HCl is added to saturated (5.4 M) NaCl. Calculate [Cl-] in the original solution and after the addition of the 12 M Hcl (before any precipitate forms). Explain this behavior in terms of Cl- in the two solutions and the equilibrium equation.
NaCl(s) = Na+ (aq) +Cl-(aq) Kc=29
One of the steps in the commercial process for converting ammonia to nitric acid involves the conversion of NH3 to NO:

The diameter of the laser beam is 5.5 mm. If the laser is pointed toward a pinhole with a diameter of 1.2 mm, how many photons will travel through the pinhole per second?
2.9 mol Fe(OH)3 and 7.7 mol H2SO4 react according to the equation 2 Fe(OH)3 + 3H2SO4 -!> Fe2(SO4)3 + 6H2O. If the limiting reactant is Fe(OH)3, calculate the amount of Fe2(SO4)3 formed. Answer in units of mol.
Further studies will refine how much water is needed for endangered species protection. States hope it will be the 130-150 KAF initially agreed upon rather than the 415 KAF the FWS thinks it is. What happen if cooperative agreement fails?
