Explanation:
Initial moles of hydrogen peroxide = 1.75 mole
Volume of the container = 25 L
Concentration of a substance is calculated by:
So, concentration of hydrogen peroxide =
The given chemical equation follows:
Initially 0.07 M 0 0
At equilibrium
(0.07-2x) M 2x x
We are given:
Equilibrium moles of hydrogen peroxide = 1.20 mole
Equilibrium concentration of hydrogen peroxide =
Evaluating the value of 'x', we get:
(0.07-2x) M = 0.048 M
x = 0.011 M
So, the equilibrium concentrations of water vapors and oxygen gas are:
The expression of for the above reaction follows:
Putting values in above expression, we get:
Hence, the value of
Gneiss is a sedimentary rock and granite is a metamorphic rock.
<h3>What are rocks?</h3>
Rocks are geological hard materials that are made up of various types which include:
- Sedimentary rocks: These are rocks that made up of various layers formed from sediments. Example is the gnesis.
- Metamorphic rocks: These are rocks that are form from pre existing rocks that undergoes some transformation. Example is granite
Therefore, Gneiss is a sedimentary rock and granite is a metamorphic rock.
