By saying that the inductor opposes changes in current. Does it actually stop current from changing?

From Wikipedia: metallic zinc at the surface of the zinc electrode is dissolving into the solution Can you explain what makes them dissolve into the solution? The solution is just a mix of Zn2+ and SO42-. Do Zn atoms react with Zn2+ or S042- ?

My question is. Will the following reaction happen if there was no solution. Zn(s) + Cu2+(aq) Zn2+(aq) + Cu(s) I suspect there should be some energy given off which will make electrons pop from the Zn nucleus. Is the attraction between the positively charged Copper ion and Zn atom is enough to...

In redox reaction one atom loses electrons and another atom gains electrons. Is it possible for a redox reaction to occur just by simply placing atoms of zinc and copper together or we need to have an oxidizing/reducing agents for this to happen?

The electrodes themselves must be electrically neutral and thus there will be no voltage? Am I right?

From the link which you posted it is said that: In this cell the zinc metal has a tendency to dissolve as ions leaving its electrons on the electrode. I can't get the order: whether it is Reaction with the solution which causes electrons to fly away from Zn metal, or it is the attraction from...

Could you please clarify on this please. What do you mean by saying the current will have a delayed response? I see that I am missing something

By let's say some electronic circuit or let's assume that I can turn the knob of the resistor with a linear speed. Still don't get the answer :)

Imagine simple RL circuit connected to a battery source. Let's assume that we are decreasing the resistor value linearly in a constant steady rate. This will make the current being increased linearly. Thus the current will be increasing in an inductor and it will cause a voltage to build up...

In a standard galvanic half-cell when Zinc rode is placed into the Zinc sulphate. What is the reaction which makes zinc to dissolve and fell into the solution. Why do electrons move away from the sides of the electrode? Are they repelled by the solution or by other ZN atoms on the electrode...

Who is the trigger of the oxidation reaction. Copper which attracts electrons from the Zinc or solution which makes Zinc losing electrons and become positively charged. I am struggling to understand what actually makes Zinc to enter the solution and leave 2 electrons behind. If there is no wire...

Does zinc react with Hydrogen ions and becomes oxidized? Zn(s) + 2H+ -> Zn2+(aq) + H2(g)

As far as I understand. To get the solution we mix sulphate and a water and get an aqueues solution with lots of cations and anions. ZnSO4 + H2O ---> Zn2+ + SO42- + H2O ---> Zn2+ + HSO4- + OH- This is the solution. Which ions react with Zn to make it dissolve in the solution?
