Zn has a lower reduction potential than Cu and so the Zn will be oxidized (lose electrons) to become Zn^2+ and the Cu^2+ in solution will be reduced (gain electrons) to become Cu(s).
Zn, Cd, Hg, Uub
You should have somewhere a list called the Activity Series. Zinc is a more active metal than silver, meaning that zinc will replace silver in a compound, but silver will not replace zinc.

Zn(s)+2AgNO3(aq)---> Zn(NO3)2(aq)+2Ag(s) There is no reaction...
Zn(+2) + CO3(-2) -----------ZnCO3
ZnSO4 (zinc sulfate) in aqueous solution ionizes to form zinc cations (Zn^2+) and sulfate anions (SO4^2). Thus, ZnSO4 ---> Zn^2+(aq) + SO4^2-(aq)
The pH of a saturates zinc hydroxide solution is 8.64. To find this in the future the formula is, Zn(OH)2 has Ksp = 4.1x10-17 Zn(OH)2 = > Zn2+ + 2OH-.
Mg, Mn, Co, Ca, Cd, Fe, Zn, Se
The amount of zinc is 0,01 moles.
No reaction will happen. This is because, Fe is less reactive than Zn and so is unable to displace Zn from ZnSO4 solution. This reverse condition will have hold true. This means the following reaction can take place. Zn + FeSO4 ---> ZnSO4 + Fe
Fe + ZnSO4 ---> Zn + FeSO4
Yes, it forms nickel,which will probably appear as a gray magnetic precipitate, and zinc chloride, which will be a colorless solution. NiCl2 + Zn --> Zn + NiCl2
Zinc (Zn), Cadmium (Cd), Mercury (Hg)
These are Zinc(Zn), Cadmium(Cd) and Mercury(Hg)
Cu is unable to displace Zn in a zinc sulphate solution because Zn is more reactive than copper and therefore has greater reducing abilities since it easily donates electrons :)
Zn is more reactive than is Cu, so it will replace the Cu. Thus, the reaction isZnSO4 + Cu ==> CuSO4 + Zn. This is an oxidation/reduction reaction.
Zn + 2AgNO3 --> Zn(NO3)2 + 2Ag Keq = [Zn(NO3)2][Ag]^2/[Zn][AgNO3]^2 You need concentrations to calculate the Keq Answer from: http://answers.yahoo.com/question/index?qid=20090210150755AAmWI7s

Yes it is... Practically, mix this two metals with HCl solution in different tubes and you will see how Mg reacts more rapidly than Zn. Besides, the Electromotive Series tells you than Mg is more active than Zn.
Zinc is most reactive of the three. So if you put a piece of zinc metal to the three solution you will observe, In the Zinc nitrate solution there is no reaction while others have. As zinc is most reactive of three, in will displace the respective metals out of their solution. If the zinc is coated with reddish covering, it is Copper nitrate. If is coated with silvery needles, the solution is Tin nitrate.Zn + Cu(NO3)2 ----> Cu + Zn(NO3)2Zn + Sn(NO3)2 ----> Sn + Zn(NO3)2Zn + Zn(NO3)2 ----> [No reaction]
Zn + CuSO4 --> ZnSO4 + Cu 1.75g CuSO4 * (1moleCuSO4/159.62gCuSO4) * (1moleZn/1moleCuSO4) * (65.38gZn/1moleZn) = .7168g Zn 2.00g Zn - .7168g Zn = 1.2832g Zn in Excess
Zn + HCl -----> Zn+ + Cl- + H2 The Zinc solid reacts with the hydrochloric acid to form Zinc Chloride (ZnCl) a soluble salt. In the reaction solution it appears that the Zinc is disappearing but it is actually becoming part of the solution in the form of ions.
Zn(s) + CuSO4(aq) --> ZnSO4(aq) + Cu(s) The copper will plate out on the zinc. The net ionic reaction is: Zn(s) + Cu+2(aq) --> Zn+2(aq) + Cu(s)
