Answer:
A
Explanation:
The total number of each type of atom always stay the same.
Explanation:
Equation of reaction:
PCl₅ ⇆ PCl₃ + Cl₂
Problem: what direction will the reaction shift towards if PCl₃ is added;
Solution:
According to Le Chatelier's principle "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
If the concentration of PCl₃ is increase, the equilibrium will shift towards the left because it is used up in that direction. More of the PCl₅ will be produced in order for the system to adjust back to equilibrium.

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

Take the formula for percent error
Accepted value minus experimental value over accepted value then multiplied by 100.
The experimental value is 4.29
The accepted value is 4.18
4.18-4.29/4.18 x 100
Use absolute value if negative
