Diffusion is the process of a substance spreading out to evenly fill its container or environment. Rate of diffusion of a gas is inversely proportional to the molar mass of the gas.
Lighter(lower) the molar mass of the gas , faster will be its rate of diffusion and heavier (higher) the molar mass of the gas , slower will be its rate of diffusion.
We have to arrange the given gases from slowest rate of diffusion to fastest rate of diffusion that means we need to arrange gases from higher molar mass to lower molar mass.
Molar mass of given gases are :
Cl = 35.5 g/mol
Xe = 131.29 g/mol
He = 4.00 g/mol
N = 14.00 g/mol
So correct order for slowest rate of diffusion (highest molar mass) to fastest rate of diffusion (lowest molar mass) is :
Xe , Cl , N , He
Xe having the highest molar mass will have the slowest rate of diffusion and He with lowest molar mass will have the fastest rate of diffusion, so option 'c' is correct.
Note : Slowest rate of diffusion = High Molar Mass
Fastest rate of diffusion = Low Molar Mass
The general formula for alkyne series is CnH2n-2
This is because alkyne is unsaturated hydrocarbon which has one triple bond and has no functional group from homologous series. Alkyne has a general formula of CnH2n-2
An example of an alkyne in ethyne with HC≡CH chemical formula ,
another example is propyne with CH3C≡CH formula

760 mmHg = 1 atm Therefore 30 atm = 760 * 3 mmHg = 2280 mmHg p1 = 700 mmHg p2 = 2280 mmHg You can compare them from there. You may also convert mmHg to atm by dividing by 760.
Your answer would be 243.2 mm Hg
Hey there!:
The reaction is as follows:
N2(g)+ 3 H2(g) ⇌ 2 NH3(g)
At equilibrium, the concentrations of the different species are as follows.:
[NH3] = 0.105 M
[N2] = 1.1 M
[H2] = 1.50 M
The equilibrium constant for the reaction is given as follows:
Keq = [NH3]² / [N2] [H2]³
Keq = (0.105)² / [1.1] [1.50]³
Keq = 0.00296 or 0.0030
The equilibrium constant for the reaction at this temperature is 0.0030.
Hope that helps!
Answer:
Carbon forms the key component for all known life on Earth.
Explanation:
Complex molecules are made up of carbon bonded with other elements, especially oxygen and hydrogen and frequently also with nitrogen, phosphorus and sulfur. Carbon is abundant on Earth. It is also lightweight and relatively small in size, making it easier for enzymes to manipulate carbon molecules.
