Two containers of the same volume are evacuated. Container 1 is maintained at a temperature of 400K and filled with oxygen gas to a pressure of 750mm Hg. Container 2 is maintained at a temperature of 200K and filled with hydrogen gas to a pressure of 750 mm Hg. Compare the two samples of gas quantitatively with regard to: a. number of molecules b. mass c. average molecular kinetic energy d. average molecular speed (rms)
How many moles of SCN-1 are there in 10.0 mL of a 0.000100 M soulution? How many grams. Show me step by step how to do these problems.
A cylinder fitted with a piston contains 3.00 moles of He gas (ideal!) at P = 1 bar and is held in a large constant-temperature bath at 400 K. The pressure is reversibly increased to 5.00 bar.
Isra fills two identical balloons at identical temperatures. She fills one with O2 gas and the other with O3 gas. Which balloon will deflate faster? Why?
