Answer:
9-10 ppm.
0.2-0.4 ppm.
Explanation:
The proton on the aldehyde group will appear at approximately 9-10 ppm whereas the methylene peak on the alcohol is the only peak 0.2-0.4 ppm for either compound. Aldehydes and aromatics are quite distinctive in the Nuclear magnetic resonance (NMR). Aldehydes show up from 9-10 ppm, usually as a small singlet; aromatic protons show up from 6.5-8.5 ppm. NMR spectroscopy is the use of NMR to study the physical, chemical, and biological properties of matter.
Answer: Which Group 1A elements are less dense than pure water at 4 degrees C? Li Na K. How does density vary with temperature? Temperature up, density down.
Explanation:
It provides evidence that each organism is related and similar in each way, leading to the conclusion of a common ancestor.<span />
Answer: The range of wavelengths of light that can be used to cause given phenomenon is 
.
Explanation:
Given: 222 kJ/mol (1 kJ = 1000 J) = 222000 J
Formula used is as follows.
where,
E = energy
h = Planck's constant = 
c = speed of light = 
Substitute the values into above formula as follows.
Thus, we can conclude that the range of wavelengths of light that can be used to cause given phenomenon is .
