Answer:
Potassium = 4s¹
Carbon = 2p²
Sulfur = 3p⁴
Barium = 6s²
Xenon = 5p⁶
Explanation:
1) Potassium is present in group one.
Its electronic configuration is:
K = [Ar] 4s¹
So its highest energy electrons are 4s¹.
2) Carbon is present in group 14.
Its electronic configuration is:
C = [He] 2s² 2p²
So its highest energy electrons are 2p².
3) Sulfur is present in group 16.
Its electronic configuration is:
S = [Ar] 3s² 3p⁴
So its highest energy electrons are 3p⁴.
4) Barium is present in group 2.
Its electronic configuration is:
Ba = [Xe] 6s²
So its highest energy electrons are 6s² .
5) Xenon is present in group 18.
Its electronic configuration is:
Xe= [Kr] 4d¹⁰ 5s² 5p⁶
So its highest energy electrons are 5p⁶
Answer:
<h2>0.03 moles </h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
We have
We have the final answer as
<h3>0.03 moles </h3>
Hope this helps you
The latest one in Hawaii would be one but since this question is from 2016, None at all is the correct answer
Answer:
Divide 6 grams by the atomic mass of fluorine.
Explanation:
Number of moles = Mass / atomic mass of fluorine
Given data:
Mass of fluorine = 6 g
How to convert into moles of fluorine = ?
Solution:
Number of moles = Mass / atomic mass of fluorine
Number of moles = 6 g/ 19 g/mol
Number of moles = 0.32 mol
So in order to convert the 6 g of fluorine into moles we have to divide the 6 by atomic mass of fluorine.
