What else can I help you with?
Which element is produced at the negative electrode (cathode)?
The element forming at the cathode will depend on what elements are present. Reduction takes place at the cathode, so whatever element is being reduced, that is the one that will be produced at the cathode.
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
Where does reduction occur in an electrochemical cell?
The cathode.
How did thomas discover the electron?
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
What would be the cathode in Mg and Zn galvanic cell?
In a galvanic cell involving magnesium (Mg) and zinc (Zn), the cathode is the electrode where reduction occurs. In this case, zinc acts as the cathode because it has a higher reduction potential compared to magnesium. Therefore, zinc ions in solution gain electrons and are reduced to solid zinc at the cathode, while magnesium oxidizes at the anode.
What would be the cathode be in a nickel and copper?
Ni(s)
What would happen to cathode rays in a vacuum?
Cathode rays in a vacuum would travel until stopped (or deflected by an electromagnetic field).
What would the cathode be in a nickel and copper electrolyte cell?
Ni(s)
What would the cathode be in a nickel and copper electrolytic?
Ni(s)

How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
What would be the cathode in a magnesium and zinc galvanic cell?
The magnesium would be the cathode in a galvanic cell with zinc. Reduction occurs at the cathode during cell operation, and in this case, magnesium is reduced while zinc undergoes oxidation at the anode.
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
What is a positive electrode?
A positive electrode is a cathode. A negative electrode is an anode.An anode is positively charged, while a cathode is negatively charged.
How can you identify a cathode nigative to an LED?
LED has two pins,one is anode(positive) and the other is cathode(negative).The smaller pin is cathode(negative) and the longer pin is anode(positive).
What would the cathode be in nickel and copper electrolytic cell?
Ni(s)
What were the two main problems of using vacuum tubes in computers?
Valves, or vacuum tubes, were large, generated tremendous heat, and were prone to failure.Vacuum tubes worked much like transistors, but required a filament to heat the cathode so that electrons could flow through the plate when there were the proper grid voltages for that. If the cathode heater burned out, the cathode would not work, and the tube would need to be replaced. Comparing to a PNP or NPN transistor, the cathode would be equivalent to the emitter, the plate would compare to the base, and the grid would computer to the collector. Comparing to an FET, the cathode would be the source, the grid would compare the the gate, and the plate would compare to the drain.
