a Spinels are solids with the general formula M²+ (M¹³+)₂ 04 (where M²+ and M¹³ are 3+ 3+ metal cations of the same or different metals). The best-known example is common magnetite, Fe3O4 [which you can formulate as (Fe³+)₂04]. (Fe²+) A crystal of a spinel Given its name, it is evident that magnetite is ferromagnetic. How many unpaired electrons are there in iron (II) and in iron(III) ions? Iron(II) ion: unpaired electron(s) Iron(III) ion: unpaired electron(s)

2 Ba2+ (aq) + Cr20,2 (aq) + H2O (I) 2 BaCro4 (s) + 2 H* (aq) Dichromate forms orange aqueous solutions and barium chromate is a white solid. Ba(NO3)2 is placed into a test tube of aqueous K2Cr207 forming a colorless solution with a noticeable amount of white solid at the bottom. Use Le Chatelier's Principles to answer the following questions. A. What would you expect to observe if HC was added to the test tube? Explain why the expected observation occurred. B. What could you add to the test tube to increase the amount of solid that would form? Explain why you chose that substance. C. You cool the test tube and notice an increase in the amount of solid formed in the solution. Explain what that suggests about the above reaction?
Zeolite A, Na₁₂[(AlO₂)12(SiO₂)₁₂] .27HO, is used to softenwater by replacing Ca2²⁺ and Mg²⁺ with Na. Hard water froma certain source is 4.5X10⁻³ M Ca2²⁺ and 9.2X10⁻⁴ M Mg²⁺,and a pipe delivers 25,000 L of this hard water per day. Whatmass (in kg) of zeolite A is needed to soften a week’s supply ofthe water? (Assume zeolite A loses its capacity to exchange ions when 85 mol % of its Na⁺ has been lost.)
The Coordination Principle describes the likely three-dimensional (i.e., polyhedral) relationship which forms between around cations.
