Bases on graham's law of diffusion, how does the speed of diffusion of neon (m=20.2) compare to the krpton (m=83.8)

2.037.

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.

∨ ∝ 1/√M.

Where, ∨ is the rate of diffusion.

M is the molar mass of the gas.

For Ne and Kr:

(∨)Ne/(∨)Kr = √(M of Kr/M of Ne) = √(83.8 / 20.2) = 2.037.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
