Classified Paper 1 for Chemistry

 

[FAHAD imtiaz]

Paper 31 was a bit hard in one part of a question what we had to write asking the name of arteries and veins of kidneys ? For kidney I wrote renal arteries and renal veins

 

[FAHAD imtiaz]

We gave the first varient it was damn tough nothing came from these topics :/

Who is this

Lol man those 5 marks questions were hard !! What did you write in that region Y on the graph ??

guy sj?? It seems he's from ksa!

 

[FAHAD imtiaz]

Lol ..

perhaps then it's because there is like a really low concentration of hydrogen ions H+ and hydroxide ions (OH–) within the electrolyte you know like from the self-ionisation of water itself, and like these were like just ignored in here or smthin it's like an exception..

Simply we can see it is upto discharge power ! Hydrogen could discharge easily!
