Answer:
Molecular Formula = N₃P₃Cl₆
Explanation:
Molecular formula is calculated by using following formula,
Molecular Formula = n × Empirical Formula ---- (1)
Also, n is given as,
n = Molecular Weight / Empirical Formula Weight
Molecular Weight = 347.64 g.mol⁻¹
Empirical Formula Weight = 1 (N) + 1 (P) + 2 (Cl) = 115.88 g.mol⁻¹
So,
n = 347.64 g.mol⁻¹ ÷ 115.88 g.mol⁻¹
n = 3
Putting Empirical Formula and value of "n" in equation 1,
Molecular Formula = 3 × NPCl₂
Molecular Formula = N₃P₃Cl₆

Answer: 1s2 2s2 2p6 3s1 3p1
Explanation:
Excitation of an electron is an elevation in energy level of the valence electron above the ground state electron.
When an electron gains energy, usually the outermost electron it moves from a orbital of lower energy to a orbital of higher energy, the element is in an excited state.
The electron configuration of ground state of magnesium is 1s2 2s2 2p6 3s1 3p2, when it gains energy the electronic configuration is 1s2 2s2 2p6 3s1 3p1 the excited state of Magnesium this is because the last electron moves from the 3S orbital to a higher energy orbital 3P
Your wight on the earth is greater because it has more gravitational pull whilebon the moon your weight is lower beacause of less gravitational pull.
