A1.000 g sample of octane (c8h18) is burned in a bomb calorimeter containing 1200 grams of water at an initial temperature of 25.00ºc. after the reaction, the final temperature of the water is 33.20ºc. the heat capacity of the calorimeter (also known as the "calorimeter constant") is 837 j/ºc. the specific heat of water is 4.184 j/g ºc. calculate the heat of combustion of octane in kj/mol.

Which statement best describes the he properties of iconic compounds ?

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.

What happens to the temperature of a substance when the average kinetic energy of its particles increases?
