Hi there,
I am not very sure what the coating is called but i think it is iron oxide. lolxx
Zinc is more reactive than copper, so it'll displace the copper & take on the sulphate ion for itself:
Copper sulphate solution + Zinc --> Zinc sulphate + copper
Copper sulphate solution is blue & zinc sulphate is colourless, so during the reaction, the blue colour will fade.
Iron is seen coating the strip-because zinc displaces it.
Iron
magnesium+copper sulphate =no reaction
When zinc sulphate and lithium react together, they form lithium sulphate and zinc as products. Zinc is a grayish-white metal, while lithium sulphate is a white solid. Therefore, after the reaction, you would observe a greyish-white solid and a white solid.
by adding hot water
There would be no reaction because copper is a less reactive metal than iron. Refer to the related link for an activity series of metals.
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
magnesium+copper sulphate =no reaction
No Reaction
it would be the same

no reaction would take place
Nope. There would be no reaction because magnesium is higher on the reactive series than magnesium. It would stay the same.
You would get a very energetic (or even explosive) reaction which would produce magnesium sulphate and hydrogen gas.
this reaction would be a single displacement reaction where Zn+2 ions would displace the the copper ions due to its slightly higher electronegativity. The overall stoichiometry would be: Zn+2 + CuSO4 --> ZnSO4 + Cu+2
As aluminium is a reactive metal, it will oxidise in air to form a hard coating of aluminium oxide which surrounds the metal. To observe the reaction of sulphuric acid and aluminium, this coating must first be specially removed. Effervescence will be observed, and hydrogen gas will be produced. aluminium + sulphuric acid (reacts to form) aluminium sulphate + hydrogen gas
MgSO4 is a stable salt, I think. Besides, this reaction would produce highly reactive H2SO4, so you would have four species in solution; perhaps some kind of equilibrium reaction. ( needs chemists edit )
ammonium iron (II) sulphate.
Iron is needed to produce iron sulphate.
