a toothpick, pencil, and log are all the same type of wood. explain which would be most dense. answer
2 answers:
Explanation:
Density is defined as the mass of a substance present in per unit volume.
Mathematically, Density =
As toothpick, pencil and log are all made up of same wood. So, this means that there will be same composition as amount of mass present in per unit volume will be the same.
Therefore, we can conclude that toothpick, pencil and log all of them will have same density.

Answer:
The bands are due to:
λmax = 289 nm n→π* transition (E = 12)
λmax = 182 nm π→π* transition (E=10000)
Explanation:
The two types of acetaldehyde transition are as follows:
n→π* and π→π*
From the attached diagram we have to:
ΔEn→π* < ΔEπ→π*
ΔEα(1/λ)
Thus:
λn→π* > λπ→π*
In n→π* spin forbidden, the intensity is low. Thus, the molar extinction E for n→π* is very low.
The same way, for π→π* spin allowed the intensity is high. Thus, the molar extinction coefficient E for π→π* is high too.
The bands are due to:
λmax = 289 nm n→π* transition (E = 12)
λmax = 182 nm π→π* transition (E=10000)
