CuSO4(aq) + Zn(s) ------------> ZnSO4(aq) + Cu(s) redox reaction
in CuSO4 Cu =+2 state
in products Cu = 0 state
so Cu reduced from +2 to 0
.in reactants Zn = 0 state
in ZnSO4 Zn = +2 state
so Zn oxidized from 0 to +2

7. Solid zinc and aqueous copper (II) bromide react in a single replacement reaction producing zinc bromide and solid copper. How many grams of solid zinc nuggets must be put into this reaction in order to recover 25.0 grams of solid copper metal. (Assume 100% yield.)
Copper(I) ion undergoes a self-redox reaction to form solid copper and copper(II) ion. a) Write the balanced equation for the reaction in water. b) In water, the equilibrium constant for this reaction is ≈106. But if the copper(I) is dissolved in DMSO, the equilibrium constant for the reaction is ≈2. Suggest an explanation.
In a copper-zinc voltaic cell, one half-cell consists of a ZnZn
electrode inserted in a solution of zinc sulfate and the other
half-cell consists of a CuCu electrode inserted in a copper sulfate
solution. These two half-cells are separated by a salt bridge.
At the zinc electrode (anode), ZnZn metal undergoes oxidation by
losing two electrons and enters the solution as Zn2+Zn2+ ions. The
oxidation half-cell reaction that takes place at the anode is
Zn(s)→Zn2+(aq)+2e−Zn(s)→Zn2+(aq)+2e−
The CuCu ions undergo reduction...
