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.

43.452

step-by-step explanation:

284 times .153 = 43.452

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
