(a) what are the molar enthalpies of pure A and pure B?

(b) What are the partial molar enthalpies of A and B at xB = 0.5?

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
