sorry not replied sooner, so sorry if yous have already done your tasks, but yeah you have to draw a table i task 1, and theres only one calculation to do in task 1,@Miyah as i said there was a calculation in task 1, i cant really tell you exactly what to do in the tasks, but task 2 was basically mixing two solutions and recording the tempreature.....

To everyone doing the written test soon, im not going to tell you exactly what came up cause that would be cheating, but basically revise your calucations for moles, enthalpy changes,e.g Q=MCT etc.  research hand warmers, and revise all your alcohol stuff....i cant even remember what the questions were, and i only did it yesterday! :L 

hoped that helped...thats the aqa CHEM3X board so if your doing a different board, dont take this in to account that it may be on your test, becuase you might have a different exam

In task 1 and 2 there are no calculations that you need to do except working out the average titre for task 1 which is quite easy. In task 2 you have to do a titration over 10 mins where in the 4th min you add the substance eg HCL. you should have done something similar to it in class with your teacher.

ive already completed tasks 1 and 2, task 1 was a titration recording your results, and task 2 was a tempreature change between two soluations, basically just recording results, ive not done task 3 yet; the written part, im doing that on Friday, so cant really help you with that, but they are the two tasks that ive done, im doing the aqa board, so if your doing a different exam board i dont know if it will be different tasks...hope that helped at all :/
