 Think again as we have before about the sorts of assumptions that you're going to make. So if you're going to use this equation then knowing that we are expecting that we're going to get a An increase in temperature from an exothermic reaction. That's what we're going to be measuring about this We're going to have to look at the specific heat of water The products will be will include a salt in there. So that won't be exactly accurate This is what we want you to think about when you're carrying out your experiments and looking at potential sources of error And where you might have any deviation between your empirical or experimental value and theoretical value, which I've given you here That's all we really want to do is just to set this one up for you Give you the opportunity in class to carry out a couple of different types of neutralization Reactions and to compare your results with the theoretical values. Good luck and thanks for watching
