How does copper reacts with acid when copper is below hydrogen in reactivity series?
Khajista
Cu does not reacts with dilute sulphuric acid but concentrated sulphuric acid reacts with copper inpresence of oxygen and heat here last two factors are responsible for the reaction of copper.

Why does Fe reacts with dil. H2SO4 to give hydrogen gas but copper does not?
Becayse Iron (Fe) is higher than hydrogen (H) in the chemical reactivity series so it displaces it forming hydrogen gas and Iron sulphate. But Copper (Cu) is lower than hydrogen in the chemical reactivity series so it cannot dispalce hydrogen thus not liberating hydrogen gas
Why does zinc reacts with DI sulfuric acid to give hydrogen gas but not copper?
If you look at reactivity series, you will find zinc to be more reactive than hydrogen while copper being less reactive than it. Therefore zinc is able to displace hydrogen from sulphuric acid while copper is not. The reaction with zinc is:- Zn + H2SO4 -------> ZnSO4 +H2 The reaction with copper is Cu + H2SO4 ---------> No reaction
What happens when iron sulphate reacts with copper powder?
Nothing happens, because copper is below iron in the reactivity series, so it can't displace iron in iron compounds
Is Hydrogen produced when Magnesium reacts with copper sulfate solution?
The activity series of metals goes something like this: Lithium Potassium Barium Calcium Sodium Magnesium Aluminum Zinc Iron Nickel Tin Lead Hydrogen Copper Mercury .............and so on..... ps, I might have left some elements out....can't remember them all... Since magnesium is higher in the reactivity series of metals, it can replace copper in a reaction. Copper is lower in the activity series of metals therefore can not replace magnesium.
Does copper burst into flames like magnesium?
No. As copper is low on the reactivity series it only releases a small amount of hydrogen and it also changes colour due to oxidisation.

What happends when magnesium reacts with acid?
Magnesium, like all metals above copper on a standard reactivity series chart, will liberate hydrogen gas.
Does copper react with dilute sulfuric acid?
No, as copper is below Hydrogen in the reactivity series
What metals does hydrogen places between in the reactivity series?
Between Lead and Copper

Why does zinc react with sulphuric acid to give hydrogen gas but copper does not?
Zinc is above hydrogen in the reactivity series while copper is below. Since zinc has a higher tendency to lose electrons than hydrogen it then displaces hydrogen ions from solution.
Does copper burst into flames like magnesium?
No. As copper is low on the reactivity series it only releases a small amount of hydrogen and it also changes colour due to oxidisation.
Is it impossible for an element to replace atoms of anothe element in a compound?
No. In a displacement reaction, that is exactly what happens. If an element low down in the reactivity series is in a compound, and you add an element that is higher placed in the reactivity series. The more reactive element will displace the less reactive element in the compound.Example:Copper Sulphate - Copper is low in the reactivity series and is in a compoundSodium + Copper Sulphate - Sodium is higher in the reactivity series than copper, and is in it's pure elemental form.Copper + Sodium Sulphate - The Sodium that is higher in the reactivity series has switched places with the Copper, which is lower in the reactivity series.FULL EQUATION:Sodium + Copper Sulphate --> Copper + Sodium Sulphate

Does copper react with acid?
It does for example with dilute nitric acid. It depends on how strong oxidant is the acid. Metallic copper must be oxidized to react with acid which can be performed by the acid itself (nitric acid, sulfuric acid) or atmospheric oxygen. Thus copper will not react with non-oxidizing acid (like hydrochloric acid) but you can notice that if you let copper with hydrochloric acid on open air, it will oxidize after time, forming green products.
