Chemistry order the relative rate of diffusion of the following gases from slowest to fastest, 1st being slowest, 6th being fastest. cl2 f2 he kr n2 o2

Answer is:

1: Kr.

2: Cl₂.

3: F₂.

4: O₂.

5: N₂.

6: He.

The lighter (smaller) particles move more quickly than heavier (larger) ones at the same temperature.

Calculate molar masses of the compounds:

M(Cl₂) = 70.9 g/mol; molar mass of chlorine gas.

M(F₂) = 38 g/mol, molar mass of fluorine gas.

M(He) = 4.002 g/mol; molar mass of helium.

M(Kr) = 83.8 g/mol; molar mass of krypton.

M(N₂) = 28.01 g/mol; molar mass of nitrogen gas.

M(O₂) = 32 g/mol; molar mass of oxygen gas.

water pollution kills aquatic life. aquatic life includes algae and other plant life that use photosynthesis. photosynthesis takes   c02 out of the air.  

c02is a greenhouse gas.
