HELLPPP PLEASE. 50PTS ITS URGENT

Ella wants to construct an electrochemical cell using the following materials :
1.Salt water (as electrolyte)
2.Copper strip
3.Zinc Strip or Aluminum foil
4.Voltmeter and/or LED (to confirm the passage of electric current)
5.Two beakers
6.Insulated wires

Questions
1.If Ella can't find the copper strip can she use copper wire?

2. Are there any other materials she will need? If so state them.

3. What can she use as a substitute for insulated wire.

4.Write a step to step procedure on how she can construct an electrochemical cell using the given materials listed above.

1. Yes, it will have the same effect.

2. No, she will not need anything else.

3. Bare wires.

4. Fill the two beakers up with electrolyte. Connect the two terminals with the wire and put electricity through. Connect the voltmeter to the circuit. And finally, put the two terminals into the two beakers.

Explanation:

Hope this helped!

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

what are the statements
