Answer:
I think #5 is its structure
Explanation:
8 groups, 1 to 7 and most people call group 8 group 0 because the noble gases in group 0 have the outer electron shell full, so for example argon has 18 electrons, so it’s structure is 2.8.8 with its outer shell full. Also the number of the last shell defies what group it’s in, for example sodium is in group 1 so it’s structure is 2.8.1. Hope this helps.
Answer:
there are 4 possible isomers
Answer:
1.81 x 10²⁴atoms
Explanation:
Given parameters:
Number of molecules = 3 moles
Unknown:
Number of atoms = ?
Solution:
To solve this problem, we are going to use the mole concept.
1 mole of any substance contains 6.02 x 10²³ atoms
So
3 mole of propanone will contain 3 x 6.02 x 10²³ atoms = 1.81 x 10²⁴atoms
