Question

3. Consider the reaction (where H:NCH,CH2NH2 is ethylenediamine): Fe3. (aq) + 3 (H2NCH2CHANH) (aq) [Fe(H2NCHCH,NH2hP (aq) Calculate the number of moles of iron/(lI) Ion when you obtain 8.0 ml of 0.40 g/mL of FeChy 6H20 solution. (b) Calculate the number of moles of ethylenediamine in 4.0g of H,NCH,CH,NHs c) Since iron(ill) and ethylenediamine react in a 1:3 mole ratio to form [Fe(H NCH,CH/NHahl (aq), what is the limiting reactant in a mixture of 8.0 ml of 0.40g/mL of FeCly 6H 0 and 4.0 g of ethylenediamine. (d) How many moles of [Fe(H2NCHCHNOhproduct do you expect to form, in theory? in Part B.4 of the Experimental Procedure, you are requested to store the green crystals of the synthesized coordination compound in the absence of light in a closed drawer. What is the purpose of storing the green crystals in the dark? 4.
