Workbook Data Chart

Postby jpevec3F » Sat Jan 24, 2015 2:46 pm

Can someone explain how to use the bottom half of the data chart given in the workbook? It gives units in E and V, and I am not sure how to convert that to bond enthalpy for the second problem. Thanks.

Those are standard potentials, but I don't think we use them until we get to electrochemistry. Which problem are you looking at?

Number 2 in the first quiz. I can't find the enthalpy of Al2O3 or AlCl3

We can look those up in the textbook. I asked about that one too because it wasn't given in the workbook but was told we will be given any information like that that we would need on the real quiz, and we can just look it up in Appendix 2A for the practice quiz.

Ok thanks so much! I was under the impression that the data chart was the only info we could look at.
