Here are some I use. Hope they r beneficialHello everyone, I need some help, can anyone please give me notes for Physics, Chemistry and Biology, thanks![]()

thank you very much sir I really appreciated, god bless youHere are some I use. Hope they r beneficial
Thank you very much sir, for helping me again, god bless youmole=volume x concentration
volume=mole x 24
4(c)(i) 0.002 (mol); 0.1 x 0.02dm3 (e.g 20cm3/1000)
4(c)(ii) 0.001 (mol); 0.002/2 (becuz its 2H2O2:1O2 SO 2:1)
4(c)(iii) 0.024 (dm3); 0.001 x 24
4(c)(iv) no change/ no effect; (as catalysts don't affect equilibrium and thus the volume of the reactants-it just speeds up the reaction)
4(c)(v) 0.048 (dm3 ); 0.024 x 2 (as concentration is doubled )-e.g 0.1mol/dm3 x 2 = 0.2 mol/dm3
Hope it helps
Good luck!
this is the group for o level... brother you're in the wrong groupCan any share biology as level notes, that are not of z notes
Thanks for the advice but my exams are done, and I am done with IGCSE, joining O levels soon (lol)th

Even at relatively low pressures, there is a 99.5% conversion of sulphur dioxide into sulphur trioxide. The very small improvement that you could achieve by increasing the pressure isn't worth the expense of producing those high pressures.hey guys
can someone help with this problem?
High pressure will increase the yield of SO3. why the reaction is carried at atmospheric pressure in the contact process?
I wanna be cool in chemistry. What are the best ways?Assalam-o-Alaikum.
