The answer for the following question is explained.
<u><em>Therefore the number of electrons present with the values n = 5, l = 2, m = -2, s = +1/2 is</em></u><u> </u><u><em>one(1).</em></u>
Explanation:
Here;
n represents the principal quantum number
l represents the Azimuthal quantum number
m represents magnetic quantum number
s represents spin quantum number
n = 5,
l = 2,
m = -2,
s = +1/2
Here, it implies 5d orbital.
In the 5d orbital, 10 electrons.
As the magnetic quantum number is -2, and so it can have 1 electron.
<u><em>Therefore the number of electrons present with the values n = 5, l = 2, m = -2, s = +1/2 is</em></u><u> </u><u><em>one(1)</em></u>
Answer:
56 g. Option 3.
Explanation:
The reaction is: CaCN₂ + 3H₂O → CaCO₃ + 2 NH₃
1 mol of calcium cianide reacts with 3 moles of water in order to produce 1 mol of calcium carbonate and 2 moles of ammonia
We have the mass of each reactant, so let's convert the mass to moles:
45 g. 1mol / 80.08 g = 0.562 moles of cianide
45 g. 1mol / 18 g = 2.5 moles of water
The cianide is the limiting reactant:
3 moles of water need 1 mol of cianide to react
Then, 2.5 moles of water will need (2.5 . 1)/ 3 = 0.833 moles
As we have 0.562 moles of CN⁻ we don't have enough
We can work now, on the reaction:
Ratio is 1:1. Therefore 0.562 moles of cianide will produce 0.562 moles of carbonate
Let's convert the mass to moles to find the answer:
0.562 mol . 100.08 g / 1 mol = 56.2 g
