electrolysis is the decomposition of a substance due to the passage of electric current

[Smiley73]

to stop metals rusting you can coat them in a more reactive metal- like zinc or aluminium- and then those can forma protective insoluble oxide coat (this is called galvinising)

 

Otherwise you could use a lump of magnesium that oxidises instead of the metal - cathodic protection. the lump of metal is the sacrificial anode

That sounds vair ominous

Capacity is the ability of a fully charged battery to deliver a specific amount of electric current over a period of time

the relative density of the electrolyte solution in a lead-acid battery can be used as an indication as to how much the cell has discharged

[Smiley73]

Porous electrodes are used to increase surface area which increases reaction rate which increases the amount of current that can be drawn

structural isomers are molecules with the same molecular formula but different structural formulae

Alkanes: CnH2n+2

prefixes:

 

meth

eth

prop

but

pent

hex

hept

oct

non

dec

[Smiley73]

naming compounds:

find longest chain

find branches

fine functional group

number things so that they have the lowest number possible

if branches on the same carbon then do in alphabetical order
