I hope the answer is right
Answer:
1.2 x 10²³atoms
Explanation:
Given parameters:
Mass of CO(NH₂) = 12g
Unknown:
Number of Nitrogen atoms = ?
Solution:
Given compound;
CO(NH₂);
In;
1 mole of CO(NH₂), we have 1 mole of N
let us find the number of moles of CO(NH₂);
Number of moles =
Number of moles = = 0.2moles
Since
1 mole of CO(NH₂), we have 1 mole of N
0.2 mole of CO(NH₂) will have 0.2mole of N
1 mole of a substance contains 6.02 x 10²³ atoms
0.2 mole of N will contain 0.2 x 6.02 x 10²³ atoms = 1.2 x 10²³atoms
In diamond, The arrangement of carbon atoms follows a tetrahedral shape. Each carbon is attached to four other carbon
atoms, forming strong covalent bonds.This arrangement of the diamond is very durable and rigidity, that's why is necessary so many energy to break it.
On the other hand, graphite, has a different geometric
arrangement. the carbon atoms are arranged in 2D sheets and each carbon is linked to three other carbon atoms, forming
hexagonal rings that are easily broken.
Here, the number of protons are different. As they have different atomic numbers, it would be: "Isobars"
Hope this helps!
