Answer:
what about carbon paired electrons? what do you need to know about them?
Explanation:
Answer:
Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.During meiosis, the cells needed for sexual reproduction divide to produce new cells called gametes.
Mass = volume x density
volume = πr²
since Diameter = 2.5 cm
then radius = 1.25cm
∴ volume = π x (1.25cm)³
≈ 6.1359 cm³
Thus mass = 6.1359 cm³ x 11.34 g / cm³
= 69.58 g
Answer:As you have asked, I will not do your homework for you but will outline the reasoning…
Find out the atomic weight of all the species involved in the problem. Three decimals is more than sufficient.
Look at the periodic table of the elements and other resources (notes!) as necessary to determine the expected valence of the species
Once you know how many of these go with those, you are cruising…
You already know that 4Al+3O2→2Al2O3
So, you are in a great position to determine the number of moles of O2 , as you know you have 14.8 mol of Al and the ratio of combination is always 4 molecules.
Explanation:
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>
