A. 1 mol of CuSO4 reacts with 1 mol Zn CuSO4 : M = 159.60 g/mol n = 2 g / 159.60 g/mol = 0.0125 mol Zn : M = 65.38 g/mol m = 65.38 g/mol x 0.0125 mol = 0.819 g Which means you would have 1.18 g Zn left over

How much of Zn is needed for all of the Cu to precipitate out in this balanced equation?
Q. Zn (s) + CuSO4 (aq) ZnSO4 (aq) + Cu (s) What mass of Zn must be added to exactly precipitate out all the copper metal in 25.0 mL of 0.500 M copper sulfate solution? I do not understand how to even start this problem. If anyone could help me through this problem with the steps that would be perfect. And if anyone could find some similar practice problems w/ solutions on the internet, that would be even better. Thank you!

Balance this chemical equation! Easy 10 points?
Q. Well, not so easy: CuSO4 + Zn aswell as pb(NO3)2 + Kl BUT more importantly: could you , for each one of them: describe their products (what they look like, I know they're lead exc), explain what I would observe if I were to look at this and explain why this is happening. I want to be a scientist eventualy, so I'm tackling a harder than usual science experiment. I need to make a plan to show to my teacher, and our school book is not that advanced, and I can't find stuffs on the internet. Answer this, thanks and please!

A. Zn + CuSO4(aq) --> ZnSO4(aq) + Cu(s) (balanced as written) You will see the copper being formed and the disappearance of the blue color which comes from the hydrated copper ions. You may be able to detect some zinc disappearing, but that's more difficult. You won't be able to see ZnSO4 since it exists as Zn++ ions and SO4= ions. Pb(NO3)2(aq) + 2KI(aq) --> PbI2(s) + 2KNO3(aq) In this reaction all you will see is the formation of yellow lead (II) Iodide precipitate. You won't see potassium nitrate because it exists as potassium ions and nitrate ions in solution.

Q. Here they give you the reactants and want you to write the products 1. NH4OH + H2SO4 ---> 2. KI + Pb (NO3)2 ---> 3. AgNO3 + CaCl2 ---> 4. NaOH + HCl ---> 5. NaOH + NH4Cl ---> 6. CuSO4 + Zn(NO3)2 ---> 7. FeCl3 + NH4OH ---> 8. CaCl2 + K2CO3 ---> 9. K2CO3 + HNO3 ---> 10. CuSO4 + NH4Cl ---> Next we are asked to write the balanced equations and state Y/N if the reactions are double replacement. 1. KBr + NaI 2. Na2SO3 + HCl 3. NH4OH + HCl 4. K2SO4 + NaOH 5. CuSO4 + BaCl2 Thanks so much. I appreciate the help so I have a reference before I hand in my lab to see if the answers I got are correct! :)

HELP!!! Balancing Double Displacement Reactions???
Q. I want to make sure I am doing them correctly. I have tried a few these on my own, but I'm not sure if there right? Use (g) or (s) to indicate gases and precipitates. Write no reaction if no evidence was observed for balancing the equation. For evidence of reaction, write (a)"Precipitate formed"(include color);(b)"Gas involved";(c)"Heat involved";(d)"No reaction observed." Evidence of each Reaction below: 1.) NaCl + KNO3 --> NaNO3 + KCL = no reaction? 2.)NaCl +AgNO3 --> NaNO3 + AgCl 3.) Na2 CO3 + HCL --> 2NaCl + 2HCO3? 4.)NaOH + HCl --> NaCl + H2O ? 5.)CuSO4 + Zn(NO3)2 --> This is what I got for this one: CuNO3 + ZnSO4. So the evidence of reaction would be "no reaction" since they are both soluble in water right? 6.)NH4OH + H2SO4 -- [cont.]
Asked by danie - Mon Oct 22 19:05:22 2007 - - 2 Answers - 0 Comments
A. 1) correct 2) AgCl is a white precipitate 3) heat involved since this is an acid base reaction and it should be 2NaCl +H2CO3 4) heat involved 5) should be Cu(NO3)2 since copper is 2+ here and there should be a blue color to the solution- but possibly no reaction since they are both water soluable- but still solution is blue. 6) here 2NH4OH+H2SO4= 2H2O +(NH4)2SO4 heat involved- acid base reaction 7) NaOH+HNO3 --> H2O +NaNO3 heat involved 8)FeCl3+ 3NH4OH--> Fe(OH)3 (solid)+ 3NH4Cl 9) complicated- Na2SO3 +2HCl--> 2NaCl +H2SO3--> 2NaCl + SO2(gas) +H2O sulfurous acid is H2SO3 --> H2O+SO2

Percipitation reactions and net ionic Equations?
Q. Perdict if a percipitiateion reaction will occur in each of the following cases. If it does, write the full balanced equation and the net ionic equation (including state symbols) to show the formation of the percipitate. If there is no reaction indicate why. a) CuSO4(aq)+Na2CO3(aq)--> b)HI+Zn(NO3)2(aq)-> c) AgNO3(aq)+NaBr(aq)->
Asked by Shiva S - Sun Nov 11 17:00:13 2007 - - 2 Answers - 0 Comments
A. Use the solubility chart. Do a double displacement reaction for each and see if each product is soluble or not. If soluble break it into ions and cross the ions out. If not, then there is a precipiate. If both products are insoluble, then there is no reaction.
