Yeah!


I'M NOT SURE IF THIS IS RIGHT but i think it might of been 2e- then H+ for the other blank, i didn't put this though :frown:

What if you said ammonia chloride?


I put Ammonia Chloride instead of Ammonium Chloride but I'm hoping we'll still get the mark as the understanding is there.

WHat did you guys put for the metal? I put that it was in layers of atoms which can slide over eachother easily allowing it to be bent and shaped ... I forgot to use the word malleable :/


That is the definition for malleable but don't worry.

For the half equation, I just put 2,2. As from past papers, I saw that same question.
They made up for C2 with C3. The difference in difficulty between the two papers was mindblowing

Yeah I said to put it in an ice bath, and measure the temperature there, I think they'll both get the mark tbh


Yea thats what i put!! I totally misunderstood the question at first and thought it wanted to do the experiment by keeping the temperature at 5 degrees for the control variable
What did u guys get for the half equation????

Thanks:smile:
In terms of the accuracy question, a lot of you are talking about using thermometers with a higher resolution or digital thermometers but I don't think that's right at all because the question asks about how to improve ACCURACY (how close the results are to the true value), not PRECISION (how close the results are to each other). Instead, I would say that improving accuracy would involve insulating the beaker or something similar to that.

I put use something that would stop heat from escaping the beaker

Arghhh one of my friends put that. But i couldnt remember the phrase 'ammonium' so i put chloride nitrate :frown:


aaa haha i could only get ammonium because it mentioned ammonium nitrate in the question after but i couldn't remember the chloride bit rip

I very much doubt you will get the mark

Would be ammonium chloride. The ion is shown on the data sheet
