... Analyze: We are given two thermochemical equations, and our goal is to combine them in such a way as to obtain the third equation and its enthalpy change. Plan: We will use Hess’s law. In doing so, we first note the numbers of moles of substances among the reactants and products in the target equati ...

... We briefly examined energy in Section 1.5. Recall that we defined energy as the capacity to do work and defined work as the result of a force acting through a distance. For example, when you push a box across the floor you have done work. Consider as another example a billiard ball rolling across a ...
