Answer:
[He]: 2s² 2p⁵.
[Ne]: 3s².
[Ar]: 4s² 3d¹⁰ 4p².
[Kr]: 5s² 4d¹⁰ 5p⁵.
[Xe]: 6s² 4f¹⁴ 5d¹⁰ 6p².
Explanation:
- Noble elements are used as blocks in writing the electronic configuration of other elements as they are stable elements.
He contains 2 electrons fill 1s (1s²).
So, [He] can be written before the electronic configuration of 2s² 2p⁵.
Ne contains 10 electrons fill (1s² 2s² 2p⁶).
So, [Ne] can be written before the electronic configuration of 3s².
Ar contains 18 electrons is configured as ([Ne] 3s² 3p⁶).
So, [Ar] can be written before the electronic configuration of 4s² 3d¹⁰ 4p².
Kr contains 36 electrons is configured as ([Ar] 4s² 3d¹⁰ 4p⁶).
So, [Kr] can be written before the electronic configuration of 5s² 4d¹⁰ 5p⁵.
Xe contains 54 electrons is configured as ([Kr] 5s² 4d¹⁰ 5p⁶).
So, [Xe] can be written before the electronic configuration of 6s² 4f¹⁴ 5d¹⁰ 6p².
D. A constant pressure calorimeter would be used because an increase in heat causes an increase in pressure.
Charge = 1200 * 1.6 * 10^-19 = 1920 * 10^-19
Time = 3.5 µs = 3.5 * 10^-6 s
But Current = charge/time = (1920 * 10^-19) / (3.5 * 10^-6)
So Current becomes 548.5714 * 10^(-19-(-6))
So we have 548.5714 * 10^(-19 + 6) = 548.5714 * 10^(-13)
So we have 5.485714 * 10^(-15)
Answer:
we can conclude that there are 0.55 moles in 22 grams of argon.
