suppose two 200.0-L tanks are to be filled separately with the gases helium and hydrogen. What mass of each gas is needed to produce a pressure of 135 atm in its respective tank at 24 degrees C?

Which phrase best describes the rock's texture? 1.jagged grains 2.coarse grains 3.rounded grains 4.non-banded grains

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

Word equation for k(s) +h2o(l) yield koh (aq) + h2
