Question 8Which statement about the complex: dichlorobis(ethylenediamine)cobalt(III) chloride, (FM =285.3 g/mol) is incorrect? (atomic mass of Co = 59 g/mol)?a. It exhibits cis- & trans- isomerismb. It is 1:1 electrolytec. It reacts with 3-fold of AgNO3(aq) to give a white precipitate.d. The %Co in it is 20.65%e. The trans isomer is more stable than cis isomer. Question 7In the gravimetric determination of % Co in Co(acac)s experiment. Why Co(II) solution andKNO2 solution are mixed while they are boiling hot?a) To decompose any unreacted H2O2b) To prevent quick precipitation of Co(II) as K2CO(NO2)4c) To induce recrystallization by evaporating most of the solvent.d) To speed up the digestion process of Co(acac)3e) To help starting the oxidation of Co(II) to Co(III) to produce K3CO(NO2)6

a. In the absorption spectrum of the complex ion Cr(NCS)63, there is a band corresponding to the absorption of a photon of light with an energy of 1.75 104 cm-1. Given 1 cm1 = 1.986 1023 J, what is the wavelength of this photon? b. The CrNC bond angle in Cr(NCS)63 is predicted to be 180. What is the hybridization of the N atom in the Ncs- ligand when a Lewis acid-base reaction occurs between Cr3+ and NCs- that would give a 180 CrNC bond angle? Cr(NCS)63 undergoes substitution by ethylenediamine (en) according to the equation Cr(NCS)63+2enCr(NCS)2(en)2++4NCS Does Cr(NCS)2(en)2+ exhibit geometric isomerism? Does Cr(NCS)2(en)2+ exhibit optical isomerism?
