oh yeah your right, our teacher told us specifically to learn lead acid, he said that well have a choice of either though...shit maybe i should learn dry cell...Rutherfordium said:in a past paper i did it asked specifically for information on a lead acid battery, was that something thats been ammended in the syllabus?
Wow, didn't realise they never asked buffer. Maybe it'll be in this year. I learnt my natural buffer, so should be alright.kangms said:Doubt Batteries are in the 6/7 marker. Last year, it was like 5 marker, and the year before, 4, the year before 7 or something. So it'll probably be around 4-5 marker. Definitely not 6+ marks, since it was in a past paper. I predict BUFFERS will be the 6/7 marker this year. They have NEVER asked that.
I don't think you can say 6/7 marks worth on buffers... that's like max. 4.kangms said:Doubt Batteries are in the 6/7 marker.

Yea.. I reckon it'll sort of be like Physics. Like 3 6mark questions or so. Also, like the Physics exam, they might reword the question to throw you off abit. But if it is 3 6 mark questions, prob Buffers (yes, im still leaning towards it), Galvanic Cell(or Batteries, same shit) and locating where Haber process (or other industrial process) and justify the reason.Kings407 said:any one else think that there could be 2 or 3 6 markers like physics had??? 2 in the core and one in the option???
i think it could be water or batteries maybe CFCs
hopefully not buffers..... batteries should be ok and same with locating a plant that could be the option one with the solvay process in industrial chemistry oh wellkangms said:Yea..
