Hello, I'm having a bit of trouble, can someone give me a step by step guide?

I really feel I'm missing out a step but I can't pinpoint it and I'm not sure which reactent I should use provided when working out Q =mc(delta)T or using it to work out the mol for the later stage of the equation to finally work out the enthalpy change?

Sorry you've not had any responses about this. Are you sure you’ve posted in the right place? Posting in the specific Study Help forum should help get responses.

I'm going to quote in Puddles the Monkey now so she can move your thread to the right place if it's needed. :yy:

In AS level:
m=mass of water (if it's neturalisation it's both the alkaline used and the acid)
C=specific capacity of water
Delta T=temperature change of water

For n it depends. What's the specific question?
