I hope this helped. Have a nice day, make sure to take care of yourself. You're loved <3
Answer:
Green light has longer wavelengths than orange light. Green light has fewer particles than orange light. Green light refracts less than orange light. That is why Green light slows down more quickly than orange light does.
H₂S

Given
ΔH fusion and ΔH vaporization of different substances
Required
The substance absorbs 58.16 kJ of energy when 3.11 mol vaporizes
Solution
We can use the formula :
![\tt \Delta H=\dfrac{Q}{n}](https://tex.z-dn.net/?f=%5Ctt%20%5CDelta%20H%3D%5Cdfrac%7BQ%7D%7Bn%7D)
Q=heat/energy absorbed
n = moles
The heat absorbed : 58.16 kJ
moles = 3.11
so ΔH vaporization :
![\tt \Delta H_{vap}=\dfrac{58.16~kJ}{3.11~mol}\\\\\Delta H_{vap}=18.7~kJ/mol](https://tex.z-dn.net/?f=%5Ctt%20%5CDelta%20H_%7Bvap%7D%3D%5Cdfrac%7B58.16~kJ%7D%7B3.11~mol%7D%5C%5C%5C%5C%5CDelta%20H_%7Bvap%7D%3D18.7~kJ%2Fmol)
The correct substance which has ΔH vaporization = 18.7 kj / mol is H₂S
(H₂S from the data above has ΔH fusion = 2.37 kj / mol and ΔH vaporization = 18.7 kj / mol)
Answer: YES!
