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?

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?
