Zn(s) + CuSO4(aq) ------ Cu(s) + ZnSO4 (aq)
The enthalpy changees for two different reactions will be determined practically. In the first, experiment delta H will be determined directly and account will be taken of heat losses by extrapolation of an appropriate graph. The second experiment involves teh inderect determination of an enthalpy change using Hess' Law. The temperature can be measured manually but this experiment is ideal for using a data logger.
In the first experiment we are trying to determine delta H for the reaction of zinc with Copper 2 sulfate producing copper and zinc sulfate. How would I solve for delta H?
In the second experiment we are trying to determine delta H for the hydration of anhydrous copper 2 sulfate. If anhydrous copper 2 sulfate powder is left in the atmosphere slowly absorbs water vapour giving the hydrate solid. The enthalpy change will need to be determined when 0.025 mol of anhydrous copper sulfate is dissolved in 50mL of water. The enthalpy change of the hydrated copper sulfate when dissolved in 50mL of water will need to be determined. Also, delta H x will need to be calculated based on the delta H of the first two solved in the previous questions.
How long does this essay have to be before I can submit? I just need some help to see how I can work this problem out I do not wish to publish anything. I am just asking a question based on the worksheet I have for homework. I am not trying to commit any copyright.
