How was it......to me it was pretty much tooo easy
i they will probably give u ecf marks . the values i got were x=3 and y=8 .Double your answers haha and as for lattice for ice i wrote crystal and bonding for ice covalentHey I did the same one!
I got the first question completely wrong since i didn't get the correct values for x and y, but do you think they will give error carried forawerd marks in the following ones? Because I didn't use the x=4 and y=10 since I thought I had the values correct. I got 6 and 16, which make nl sense!
For the one on lattices and all that, what type of lattice is ice? And the bonding between iodine?
Moles of Iodine in the original solution= 0.2*50/1000=1x10-2how to do Question 1 ,part d (i)
When you plot you will get 2 patterns shown on the graph. One horizontal and the other slant line.Guys O/N 2015 P52 q2b part ii, please help. How do I draw the 2 best fit lines and MS even says something about horizontal line???
When you plot you will get 2 patterns shown on the graph. One horizontal and the other slant line.
Draw to different lines (one for the slant and one for the horizontal)
Extend both of the lines until they intersect, find the x value of the point of intersection.
I got 0.0248 (answers will obviously differ by a specific range)
Yes exactly last 3 points!I draw the horizontal line where the y value becomes same right? Like last 2-3 points?
But MS says 2 straight lines and then level off, do I need to draw 2 slanting "best fit" lines through the first few points excluding the horizontal points??? Or just simply 2 lines, one slanting and one horizontal??
Yes exactly last 3 points!
No no, just one best fit slant, and one horizontal (Last 3 points).... Like total of 2 best fits as the questions asks. And record the x value of the point of intersection.
Though 2 years aren't much but I did like from 2010, and the lastest ones are more important, so you'd do fine.Okay thank you so much. How's your prep for tmrw's p5? I'm writing paper 52, wbu? I've done papers only from 2014-2016. Any tips?
You got my inbox right? I am not allowed to post long passages, I don't even know why!Okay thank you so much. How's your prep for tmrw's p5? I'm writing paper 52, wbu? I've done papers only from 2014-2016. Any tips?
Draw a glass lid in between both the reactants, that can be dragged up for them to come in contact!Also any idea, how do we keep reactants separate until the reaction starts?
like maybe tie a thread to crucible and put the bung. then use thread to empty it. I think I read something like that

Did you do all variants?

I also read another method somewhere. That is to use a DIVIDED FLASK to separate the reagents. To start the reaction, just stir the flask, reactants will be mixed, and the reaction will start.Draw a glass lid in between both the reactants, that can be dragged up for them to come in contact!
OR
You can keep one reaction in some small cylinder which is attached to a small string. To start the reaction, the string is pulled, and the cylinder falls, causing the reactants to mix.
