Chlorofluorocarbons such as ccl 3 f and ccl 2 f 2 have been linked to ozone depletion in antarctica. as of 1994, these gases were found in quantities of 261 and 509 parts per trillion (10 12 ) by volume (world resources institute, world resources 1996–97). compute the molar concentration of these gases under conditions typical of (a) the mid-latitude troposphere (10°c and 1.0 atm) and (b) the antarctic stratosphere (200 k and 0.050 atm).

What is the ph of a 0.0010 m hno3? 1.0 3.0 4.0 5.0

How does the digestive system interact with the circulatory system? a. messages sent as electrical impulses from the digestive system are transported throughout the body by the circulatory system. b. nutrients taken in and broken down by the digestive system are carried to various parts of the body by the circulatory system. c. nutrients and gases are absorbed by organs in the circulatory system. then, they are transported to all parts of the body by organs in the digestive system. d. oxygen and carbon dioxide are exchanged by organs in the digestive system, and the gases are carried to the rest of the body by the circulatory system.

In the haber reaction, patented by german chemist fritz haber in 1908, dinitrogen gas combines with dihydrogen gas to produce gaseous ammonia. this reaction is now the first step taken to make most of the world's fertilizer. suppose a chemical engineer studying a new catalyst for the haber reaction finds that 671 liters per second of dinitrogen are consumed when the reaction is run at 271c and 0.99atm. calculate the rate at which ammonia is being produced. give your answer in kilograms per second. round your answer to significant digits.
