Question 1: (answer in place of item 14)
A gas at 300 K and under 1 bar of pressure takes up 1.2 L of volume.
The gas is quickly compressed to 9 bars and the new temperature is measured to be 1200 K.
Use the combined gas law to calculate the new volume of the gas. Show your work!
Question 2:(answer in place of item 15)
Explain one assumption made by treating a gas as ideal. What would be the consequences if this assumption turns out to be untrue?
Question 3:(answer in place of item 16)
Two identical pressure cylinders show the same pressure on the gauge. They both are at room temperature. One contains methane (CH4) and the other contains Nitrogen (N2).
Can you definitely tell which is which by weighing the cylinders? Why or why not?
Question 4:(answer in place of item 17)
2 moles of Sodium Azide (NaN3) produces about 3 moles of Nitrogen (N2) in a car's airbag. How many moles of NaN3 are needed to fill a 65 L airbag? Assume the gas is produced at a temperature of 30 °C.
