Cylinders of compressed gas are typically filled to a pressure of 200 bar. for oxygen, what would be the molar volume at this pressure and 25 °c based on (i) the perfect gas equation, (ii) the van der waals equation? for oxygen, a = 1.364 dm6 atm mol−2, b = 3.19 × 10–2 dm3 mol−1.

What are the charges of the subatomic particles by choosing the answer from the drop down menu. protons have a (+1,0,or-1). (protons,neutrons,electrons) have a 0 charge. 3.) electrons have a (+1,0,-1)

100 points answer quick the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

8.98 dm3 of hydrogen gas is collected at 38.8 °c. find the volume the gas will occupy at -39.9 °c if the pressure remains constant.
