123 005w of heat is removed from water vapour (at 373k) condensing on the outer surfaces (at 363k) of an array of cylinders of length 0.6m and diameter 0.05m. how many cylinders are needed if the heat transfer coefficient is 3000w/m2k? hints: round off to the nearest integer and use newton's law of cooling.

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
