Or if you don't want those, you could just write FO (false origin).
this person posted it and i have a doubt in the same quessorry 4 being a pain in the head but i still didnt get it ....how do we use c1v1=c2v2 ...they havnt given anything apart from the con of NaoH ..the question asks us 2 prepare solutionsof an appropriate range of con

The expression is (vol of acid+vol of alkali)x4.3x(change in temp) / moles of NaOHHey guys, very small doubt please try to help out!
For MJ 2010 51 The (i) part of Q1
How do you get the expression? What it it?
I get the (-) sign but the expression ?
man read it awesomlysorry 4 being a pain in the head but i still didnt get it ....how do we use c1v1=c2v2 ...they havnt given anything apart from the con of NaoH ..the question asks us 2 prepare solutionsof an appropriate range of con
The expression is (vol of acid+vol of alkali)x4.3x(change in temp) / moles of NaOH
This is because enthalpy change of neutralization is per 1 mole of H2O. And according to the equation,moles of H2O=moles of NaOH..i.e its 1:1
Near where the origin would have been, the bottom left of the grid.OHhh thankyou! Where would I write that??
They give you alot of lines to write for just 4 marks or 5 marks max and ask you to include a few points only why is thatare doubts left ??

I think another good strategy to do a better practice is to start revising paper together!
Plan:
we would pick a qp
give approx 15 mins to it
mean while discuss it
and then move to next question
Results:
it would be healthy for everyone
we could generalize the trend
and all the problems and doubts would be swept out as whole
so what you say?
sure.. here:can u upload ur table?
