The two lines show that these are the only two lines that do not cause energy transition in the sodium atom. Option D
<h3>What are the two lines in the spectrum of sodium atom?</h3>
The spectrum of the sodium atom appears as a doublet. This implies that there are two lines in the spectrum and they appear as bright yellow lines that are not spaced apart in the spectrum.
The two bright yellow vertical lines in the spectrum shows that these are the only two lines that do not cause energy transition in the sodium atom.

Explanation:
Answer:
K8S4O16 or K8(SO4)4 depending on if the SO4 is supposed to represent sulfate or not
Explanation:
Find the molar mass of K2SO4 first:
2K + S + 4O ≈ 174 g/mol
Divide the goal molar mass of 696 by the molar mass of the empirical formula:
696 / 174 = 4
This means you need to multiply everything in the empirical formula by 4:
K2SO4 --> K8S4O16 or K8(SO4)4 depending on if the SO4 is for sulfate or not
