Chapter 5: Gases

Section 5.1: Substances that exist as gases

READ

Take home points:

- Air is 78% N2, 21% O2, 1 % other
- Many elements exists as gases, H2, N2, O2, halogens and the noble gases.
- There are other molecular substances that exist as gases, HCl, CO, CO2, NH3 (ammonia), CH4 (methane), NO2, SO2, H2S.
- Gases:
- fill the volume of space that exist in,
- are compressible,
- when 2 gases are mixed, they will mix together to make a homogenous mixture,
- have a density (g/mL), but much lower than a solid or liquid.
