    Chemistry--> thermochem question

    Okay, so the question gives the following:
    a reaction between Copper II sulfate and Sodium hydroxide, double displacement
    50 mL sodium hydroxide (0.6M), 2.39 grams copper II sulfate
    Tfinal=24.6 Tinitial=19.3
    Determine the enthalpy of solution (I'm assuming it means "of Cu II sulfate" --> The one that would likely be solid initially.

    I am linking to my handwritten work, crude as it is, and hopefully you guys can have a look and approve! We weren't given answers to check from so I have no idea if the answer is even correct.

    **** Look at #2 ! theres the remnants of question 1 at the top ***

    Are you looking for standard enthalpy of formations?

    in other words have you seen the equation

    deltaH_{reaction}= \sum deltaH_f (products)- \sum deltaH_f(reactants)?

    No, htis one isn't standard enthalpy of formations. I have seen the equation, and I know what it is, but this question is definately done the way I have begun to complete it. Thanks though!
