You place a balloon in a closed chamber at standard temperature and pressure (stp). you cool the chamber to half of its original temperature while leaving the pressure constant. what happens to the balloon? it stays the same volume. it decreases to one-half of its original volume. it doubles in volume. it expands to four times its original volume.

According to coulomb's law, how would the electrical force between particles change if the product of their electrical charge increased?

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
