would be oil and water.lf you mix oil and water and shake them a cloudy suspension is formed
this is correct answer
I hope it's helpful for u....

Answer:
The order of increasing speed is: Cl₂ < CO₂ < Ar < N₂ < H₂.
Explanation:
- Thomas Graham found that, at a constant temperature and pressure the rates of effusion of various gases are inversely proportional to the square root of their masses.
<em>∨ ∝ 1/√M.</em>
where, ∨ is the rate of diffusion of the gas.
M is the molar mass of the gas.
Molar mass of N₂ = 28.0 g/mol.
Molar mass of H₂ = 2.0 g/mol.
Molar mass of Cl₂ = 70.9 g/mol.
Molar mass of CO₂ = 44.0 g/mol.
Molar mass of Ar = 39.94 g/mol.
∵ Molar mass of Cl₂ > Molar mass of CO₂ > Molar mass of Ar > Molar mass of N₂ > Molar mass of H₂.
<em>Remember that ∨ ∝ 1/√M.</em>
∴ The speed of H₂ > N₂ > Ar > CO₂ > Cl₂.
<em>So, the order of increasing speed is: Cl₂ < CO₂ < Ar < N₂ < H₂.</em>
