Ch3sh is polar because it has polar bonds & the net dipole is nonzero
Answer:
a) The functional group that will be evident in the IR spectrum is the OH group.
b) OH group appears between 3200-3600 cm⁻¹
c) An important impurity that have the same functional group is water.
Explanation:
Eugenol is a chemical substance that consist in a benzene that have in 1 an alcohol, in position 2 a methyl ether and in position 4 an 1-propene bonded by the terminal alkyl carbon.
a) Having this in mind, the functional group that will be evident in the IR spectrum is the OH group.
b) This OH group appears between 3200-3600 cm⁻¹
c) An important impurity that have the same functional group is water. When you have water in your sample a big signal will appear in this zone and it is possible that overlapes the OH signal of eugenol.
I hope it helps!
You have to do a report :

So
the truck efficiency is 38%.
They must make sure that all things pointed out are fact, not opinion.
The answer is: D.unstable nuclei emitting high-energy particles as they formed more stable compositions.
Those high-energy particles are alpha particles
, beta particles
, gamma radiation.
For example, the decay chain of ²³⁸U is called the uranium series.
Decay start with U-238 and ends with Pb-206. There are several alpha and beta minus decays.
Antoine Henri Becquerel (1852 – 1908) was a French physicist and the first person to discover evidence of radioactivity.
Becquerel wrapped fluorescing crystal (uranium salt potassium uranyl sulfate) in a cloth, along with the photographic plate and a copper Maltese cross.
Several days later, he discovered that a image of the cross appeared on the plate.
The uranium salt was emitting radiation.
Because of this discovery, Becquerel won a Nobel Prize for Physics in 1903, which he shared with Marie Curie and Pierre Curie.
