They are atoms. a molecule is made up of atoms.
Answer:
B)
Explanation:
because the wind is moving the sand and the rain moves the soil
16) weathering and erosion
Answer:
no equivalent peak, upfield between 0 and 3 ppm
Explanation:
NMR stands for nuclear magnetic resonance. It is a spectroscopic technique that is used for observing the local magnetic fields around an atomic nuclei. It is used to study the chemical, physical and biological properties of the matter.
In the context, the structures of the benzaldehyde and the benzyl alcohol are distinguished by the proton NMR. The hydrogen atom of aldehyde appears downfield between 9 and 11 ppm and also there is no equivalent peak for the alcohol.
The methylene hydrogens will only be significant upfield between the 0 and 3 ppm peak between the given structures.
