Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends". For a particular dive, 35.0 L of He at 20.5 °C and 1.50 atm and 15.0 L of O2 at 20.5 °C and 1.50 atm were pumped into a tank with a volume of 7.50 L. What is the total pressure (in atm) in the tank at 20.5 °C? a. 3.00 atm
b. 1.50 atm
c. 20.5 atm
d. 7.50 atm

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

here are some of the ways in which chemical and nuclear reactions differ.
