Remarkably, a catalytic system that uses light energy to hydrolyze water into hydrogen h2(g) and o(g) has been devised (science 334, 2011: 645-648) to capture and efficiently store solar energy. hydrogen is "clean burning" in that it yields only h2o. in this problem you will contrast the combustion of 1 kgh2(g) to that of 1 kg of n-octane.
