Chemistry Question

When 20.0 mL of 1.0 x 10^-12 M CoCl2 are added to 20.0 mL of 6.0x10^-9 M CaS, a precipitate will____________ because _____________? a) not form, Qsp>Ksp b) not form, Qsp<Ksp c) not form, Qsp=Ksp d) form, Qsp>Ksp e) form, Qsp<Ksp Note: after finishing the problem, if not hard can you please give me a similar example of the problem?

3. Calculate the concentration of carbonate ion in a saturated solution of CdCO3 (Ksp – 1.0 × 10–¹2). O 3.5 x 10-2M O 1.0 x 10-4M O2.7 x 10-2M O 3.5 x 10-4M O 1.0 x 10-6M X Incorrect Check out video Electrolytes for concept and Dissolution and Solubility Product Constant Part I (from time - 4:50) for examples. For an ionic compound A, By, the solubility product of a saturated solution can be found by the following equation: Ksp = [A] [B]", where [A] is the saturated concentration of ion A. 4. Check ALL of the following substances which will conduct electricity in the form given:

123 mL of a 0.352 M Ca(NO3)2 solution is mixed with 251 mL of a 0.254 M  solution of NaF at 25ºC. Calculate Qsp for the precipitate formed.

Answer: yes, 0.065grams How do I find precipitate, I know it precipitates, but I don't know how to solve how many grams of precipitate there is. Solve step-by-step, on paper please

Part 1 Feedback A solution is 0.0111 Min both Brr and SO, A0.257 Msolution of lead(I) nitrate is slowly added to it with a buret. The anion will precipitate from solution first. (K, for PbBrz 6.60 x 10 K, for Pbso, - 2.53 x 10 Part 2 Feedback What is the concentration in the solution of the first anion when the second one starts to precipitate at 25°C? 011

PLease Help! Q: Calculate the molar solubility, s, of calcium iodatein 0.020 M Ca (NO3)2 , a completely dissociated strong electrolyte. (NO3- ion does not chemically interact with either Ca2+ or IO3-) Assume that Ksp for Ca(IO3)2= 2.0e-6   Information that I have so far... Material Balance for Calcium: [Ca2+]= s+0.020 Material Balance for Iodate: [IO3-]=2s Ksp= 2.0e-6 = [Ca2+][IO3-]2= (s+0.020)(2s)2   Thank you!!

We received 15000 Ci of 28Mg, present as Mg(NO3)2 and want to dissolve is in 10 mL water at pH8. Will we form a precipitate or will the solid entirely dissolve?   Only typed solution
