Yeh, thats pretty much it. You just need to kno that modelling the polymers will give you an idea of the polymer structure, its a really basic experiment.

A Zeolite is a catalyst used for cracking alkanes, and they are generally crystalline aluminosilicates( compounds of aluminium, silicon and oxygen, with some other extra metal ions attached). Generally Aluminosilicates have no defined shape, but the zeolites have a very ordered shape, giving...

Well, thats if you use a KOH electrolyte, most dry cells use Ammonium Chloride Electrolytes, which isn't harmful. KOh is used more commonly in alkaline and button cells.

Yeh, they both look exactly the same, just some small differences: Dry Cell Anode Reaction: Zn(s) --> Zn^(2+) + 2e^(-) (Zinc casing is Anode) Alkaline Anode Reaction: Zn + 2OH^(-) --> Zn(OH)2 + 2e^(-) (Powdered Zinc around the central Steel/brass electrode form the anode) Dry Cell Cathode...
