Answer:
The equilibrium concentration of hydrogen gas is 0.0010 M.
Explanation:
The equilibrium constant of the reaction = }
Moles of hydrogen sulfide = 0.31 mol
Volume of the container = 4.1 L
Initially
0.076 M
At equilibrium
(0.076-2x) 2x x
The expression of an equilibrium constant :
Solving for x:
x = 0.00051
The equilibrium concentration of hydrogen gas:
Answer : The volume of consumed are,
L.
Explanation :
The balanced chemical reaction will be:
First we have to calculate the moles of Al.
Molar mass of Al = 27 g/mole
Now we have to calculate the moles of .
From the reaction we conclude that,
As, 4 mole of Al react with 3 moles of
So, 2 mole of Al react with moles of
Now we have to calculate the volume of consumed.
As we know that, 1 mole of substance occupies 22.4 liter volume of gas.
As, 1 mole of occupies 22.4 liter volume of
gas
So, mole of
occupies
liter volume of
gas
Therefore, the volume of consumed are,
L.
