1. Which statement is NOT true about simple cells?
  • A.   Cells contain chemicals which react to produce electricity
  • B.   The voltage produced is dependent on the electrolyte used
  • C.   A battery is two or more cells connected in parallel
  • D.   The voltage produced is dependent on the type of electrode used
2. The diagram shows a simple cell.

 

Which combination of electrodes and electrolyte would NOT give a reading of zero on the voltmeter?

simple cell with electrodes
  Electrode X Electrode Y Electrolyte
A Copper  zinc Sodium chloride solution
B copper copper Sodium chloride solution
C Zinc  copper water
D Zinc zinc water

3. Are alkaline batteries rechargeable or non-rechargeable and why?

  Rechargeable? Reason
A Rechargeable The chemical reactions are reversible when an external electrical current is supplied
B Rechargeable The chemical reactions are not reversible when an external electrical current is supplied
C Non-rechargeable The chemical reactions are reversible when an external electrical current is supplied
D Non-rechargeable The chemical reactions are not reversible when an external electrical current is supplied
4. A non-rechargeable cell stops producing a voltage when ...
  • A.   the cell has been used for a set amount of time
  • B.   the cell reaches its ‘use by’ date
  • C.   one of the reactants runs out
  • D.   the cell becomes too hot
5. What is an advantage of a rechargeable cell?
  • A.   Some of the energy in recharging is wasted as heat
  • B.   It can only be recharged a finite number of times
  • C.   It is expensive to manufacture compared to non-rechargeable cells
  • D.   It reduces the need to mine for more metals and materials
6. In addition to fuel, what other chemical is need in a fuel cell?
  • A.   nitrogen
  • B.   oxygen
  • C.   petrol
  • D.   methane
