Answer:
5s
Explanation:
The atomic sublevel with the next highest energy after the 4p is 5s.
Based on Aufbau's principle; the sublevels with lower energies are filled up before those with higher energies.
Sublevels do not fill up based on numerical order. The pattern of filling is shown as:
1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p
Answer:
C4H10
Explanation:
Remark
Every periodic table is different. I'm going to use approximate numbers.
Emperical Formula Mass
2C = 2 * 12 = 24
H5 = 5 1 5
Emperical Formula Mass = 29
Solution
To get the molecular Molar Mass, you use
Molecular Molar Mass = number of mol of each constituent * empirical molar mass
Molecular mass = 58.14 rounded to 58
empirical mass = 29
moles = constitutent = ?
58 = 29 * mols constituent Divide by 29
2 = moles constituent
Answer
(C2H5)_2
