In the experiment, what is the resulting color of the FeCl3 solution after Reaction: FeCl3 + addition of ammonium thiocyanate? NH4SCN + NH4CI + Fe(SCN)C12 O Dark pink O Yellow O Orange O Red

Which of the Ksp expressions are correctly written?     Zinc phosphate, Ksp = [Zn2+][PO43-]     Lead (II) iodide, Ksp = [Pb2+]2[I-]     Calcium fluoride, Ksp = [Ca2+][F-]2     Gold (III) chloride, Ksp = [Au3+][Cl-]

Why the reaction is fastest for Ni and slowest for Cr?

For each of the following reactions, indicate if there is something wrong with the reaction. If something is wrong, say what it is. a) 2H2I + Oz+2H,Om b) Ca + HzO + CO + Ha Na + Hal + NH3 CE,O70 + H2O → 2HBrOejaql FeSO) + 2N2CE →Na,SO + FeCt AlCaa + H2Ou → Al(OH); + CH4) Pb(NO3)2ag) + K,COsjag) PbCOslas) + 2KNO3lag) HBrag) + Ba(OH)a 2H;O + BaBragl CaFa + HaSOejag 2Hfg + CasOe c) d) e) f) h) i) 2PbS + O2+ 2P6O + 2S02
