Suggest pairs of reactants you could use in double replacement reactions to synthesize the compounds below. Include sufficient detail to make it clear how the product would be isolated (e.g. mix equal molar solutions of A and B, filter, evaporate the filtrate). Appendix 3 might be useful for this exercise. (6 points) a. calcium oxalate b. lithium iodide c. strontium acetate
