Suppose 10.9g of iron(II) bromide is dissolved in 100.mL of a 0.80M aqueous solution of silver nitrate. Calculate the final molarity of iron(II) cation in the solution. You can assume the volume of the solution doesn't change when the iron(II) bromide is dissolved in it.Round your answer to 3 significant digits.
The crystal lattice enegery for LiBr(s) is -818.6 kJ/mol at 25 degrees Celcius. The hydration energy of the ions of LiBr is -867.4 kJ/mole at 25 degrees Celcious (for infinite dilution).
The reaction between 1-chlorobotane results from treating it with sodium hypochlorite with HCL by the following reactions NaOcl + HCL yields HOCl + NaCl; HOCL+ HCl yields Cl2 + H2O.
if the reaction between iron III ion and thiocyanate ion yielded an equilibrium concentration of .15M for each of these ions, what is the equilibrium concentration of the red iron III-thiocyanate complex

Calculate the molarity of urea in a soln prepared by dissolving 16 g of urea (MM= 60.0 g/mol) in 39 g of H20. The density of the soln is 1.3 g/ml.
Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 J/ g.C and 1.00 g/mL ] and that no heat is lost to the calorimeter itself, nor to the surroundings.
