For Q15, with experiment 2 being carried out at a lower temperature, doesn't this mean if the number of moles of products formed in both reactions is the same, the products in experiment 2 will occupy a smaller volume than those in experiment 1 (since volume is proportional to temperature)? So wouldn't we need to increase the number of moles of the limiting reactant, which is the zinc, so that more moles of products will be formed hence the same volume will be occupied?
Have my resit in a few days and this was a real lifesaver. Much appreciation from the UAE!
Good luck with your resit!
Hey me too 😭. I hope it goes well
Thanks for the wishes. Best of luck to you too @foshomustafa5000
aren't they all basically just trial and error?
how do you differentiate btw them

Thank you so much, you’re an Angel!
