cells and batteries

Question 1

electrochemical cell (simple cell)

Answer 1

a basic system made up of two different electrodes in contact with an electrolyte

Question 2

electrolyte

Answer 2

a liquid that contains ions which react with the electrodes

Question 3

how do electrodes and electrolytes conduct electricty?

Answer 3

chemical reaction between the electrodes and the electrolyte set up a charge difference, if the electrodes are connected by a wire, then charge is able to flow

Question 4

what effects the voltage of a cell?

Answer 4

the difference in reactivity
the type and concentration of the electrolyte

Question 5

for a bigger voltage…

Answer 5

a bigger difference in reactivity

Question 6

battery

Answer 6

connecting two or more cells together in series

Question 7

non-rechargeable batteries

Answer 7

alkaline batteries

Question 8

when do non-rechargeable batteries stop producing a voltage?

Answer 8

when one of the reactants has been used up so the chemical reactions stop

Question 9

how are rechargeable batteries recharged?

Answer 9

by connecting them to an external current
