Asyringe of volume 20 ml has just been used and now lies empty on the doctor's desk. the pressure in the office is 100,000 pa. assume that the air is an ideal gas consisting of nitrogen n2 (80%) and oxygen o2 (20%) molecules. k=1.38×10-23 j/k and the molar mass of oxygen is 32 g/mol. the syringe must be heated to high temperatures to sterilize it. when the syringe is at its maximum temperature, the number of oxygen molecules is 6.5 x 1019 (but the pressure, volume, and percent oxygen remain the same), what is the rms speed of the oxygen molecules?

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
