) An unknown noble gas is said to effuse at a rate of 103.0 s, with the same volume of gas, a sample of nitrogen gas can effuse at a rate of 123.0 s. Calculate the molar mass and identify the noble gas.
1.) An unknown noble gas is said to effuse at a rate of 103.0 s, with the same volume of gas, a sample of
nitrogen gas can effuse at a rate of 123.0 s. Calculate the molar mass and identify the noble
gas.
2.) A group of scientists developed a 100.0mL stainless steel cylinder that has an optimum pressure
capacity of 5.00 atm. A sample of carbon dioxide at 30°C and 2.56 atm, will be placed in a heating
chamber to reach a temperature of 250°C. Will the pressure inside exceed the optimum capacity of the
stainless steel cylinder? Justify your answer by comparing the new pressure and optimum pressure.
3.) The industrial process of producing acetylene gas is by reacting calcium carbide with water as shown
in the equation: CaC2(s) + H2O(l) → Ca(OH)2(aq) + C2H2(g) (unbalanced)
If a 75.0 L tank of acetylene was to be filled completely with acetylene at 30°C at 0.970 atm, how much
calcium carbide (in grams) will be needed?
