<u>Answer:</u> The concentration of ammonia in the equilibrium mixture is 0.022 M
<u>Explanation:</u>
We are given:
Equilibrium concentration of hydrogen gas = 0.324 M
For the given chemical equation:
<u>Initial:</u> a
<u>At eqllm:</u> a-2x x 3x
Evaluating the value of 'x':
So, equilibrium concentration of nitrogen gas = x = 0.108 M
Equilibrium concentration of ammonia gas = (a - 2x) = [a - 2(0.108)] = (a - 0.216) M
The expression of 
for above equation follows:
![K_c=\frac{[N_2][H_2]^3}{[NH_3]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BN_2%5D%5BH_2%5D%5E3%7D%7B%5BNH_3%5D%5E2%7D)
We are given:
Putting values in above expression, we get:
Equilibrium concentration of ammonia gas = (a - 0.216) = [0.238 - 0.216] = 0.022 M
Hence, the concentration of ammonia in the equilibrium mixture is 0.022 M
Hi!
Why is second ionization energy larger than first ionization energy?
The reason second ionization energy is larger is because it takes more energy to remove an electron from a poistively charged ion than it does from an neutral atom.
Answer:
like i said put them all in numeral order and youll get them right
Explanation:
Answer:
The correct option is methane :
.
Explanation:
Average speed of the gas molecules id given by expression:
k = Boltzmann cosnatnt
T = Temperature of the gas molecules = 355 K
m = molecular mass of the molecule
Molar mass of methane = 18 g/mol
Molar mass of neon = 20.18 g/mol
Molar mass of ethene = 28 g/mol
Molar mass of chlorine gas = 70 g/mol
Lower the value of molar mass of gas molecule higher will be the average speed.So, from the given options methane gas greatest average seed because it has lowest molecular mass
<span>In a titration, the substance that is unknown and being identified is called analyte. A titration is where a known solution or concentration called the titrant is used to identify and measure an unknown substance which is the analyte.</span>
