D. The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced. The conservation of the mass is a fundamental law of chemistry and physics. It indicates not only that during any experiment, including if it involves a chemical transformation, the mass is conserved, but also that the number of elements of each chemical species is conserved. Like any law of conservation it is expressed by a conservation equation.

damaskus [11]

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.
