Synthesis of a Bromoalkane (n-Bromopropane)

SOLVED: Synthesis of hexammine cobalt (II) chlorideIn a 250 mL three-necked flask with a stir bar, gas inlet tubeand reflux condenser with pressure relief valve, 6.0 g CoCl2 · 6H2Oare suspended in 15 mL N2-saturated water under a nitrogenatmosphere. Thereafter, while warming, NH3 is passed in until thesolid has almost completely dissolved. With further introduction ofNH3, a flesh-colored precipitate separates out, which is separatedoff via a protective gas frit after the reaction mixture has coo

SOLVED: Consider the insoluble compound cobalt(II) hydroxide Co(OH)2. The cobalt(II) ion also forms a complex with ammonia. Write a balanced net ionic equation to show why the solubility of Co(OH)2 (s) increases in the presence of ammonia and calculate the equilibrium constant for this reaction for Co(NH3)6. Kf = 7.7x10^4. Use the pull-down boxes to specify states such as (aq) or (s).

SOLVED:Cobalt(II) oxide is used as a pigment in ceramics. It has the same type of crystal structure as NaCl. When cobalt(II) oxide is exposed to X-rays with λ=154 pm, the XRD pattern contains strong peaks at 2 θ=42.38^∘, 65.68^∘, and 92.60^∘ . Determine the values of n to which these peaks correspond, and calculate the spacing between the crystal layers.
