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.
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
it is because hydrogen gas usually liberates when an acid reacts with metal
Copper does not evolve hydrogen gas when reacting with dilute sulfuric acid because copper is below hydrogen in the reactivity series. This means that copper is not reactive enough to displace hydrogen from sulfuric acid to form hydrogen gas. Instead, copper reacts with sulfuric acid to form copper(II) sulfate and water.
Copper is less reactive than hydrogen, so it does not displace hydrogen from dilute acid violently. The reactivity series shows that copper is lower in the series than hydrogen, meaning it is less likely to displace hydrogen in a chemical reaction.
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

Magnesium, like all metals above copper on a standard reactivity series chart, will liberate hydrogen gas.
No, as copper is below Hydrogen in the reactivity series
Between Lead and Copper

Copper does not react with hydrochloric acid because it is not reactive enough to displace hydrogen from the acid. Copper is below hydrogen in the reactivity series, so it cannot displace hydrogen ions to form copper chloride and hydrogen gas.
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.
Probably nothing: Hydrogen is higher than copper in the electromotive series, so that copper can not displace hydrogen from its compounds,
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.
