Solutions Review...watch this "Crash Course" video (don't worry about taking notes).

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.
