Elemental nitrogen is a colorless gas at room temperature. Under typical conditions, its density is 1.15g/L.
Elemental oxygen is also a gas at room temperature. The density of oxygen gas is 1.31g/L. Under extreme
conditions, nitrogen can react with oxygen to produce brown nitrogen dioxide gas.
a. There is only one chemical property in the list above. State what it is. Explain.
b. None of the properties listed is an extensive property. Explain why not.
c. Calculate the volume of 2.50g of nitrogen and the volume of 2.50g oxygen using the densities give here.
