Hearing loss due to sound energy damaging the nerve cells in the inner ear. Many animals behavior is influenced by sound energy. They learn to associate events with sounds, so they run when something crunches in the dry grass (might be a coyote), but won't be bothered by the sound of a waterfall. Mood is affected by sound energy. A wine glass can break with sound energy, if the frequency matches the resonant frequency of the wine glass and the amplitude is great enough (one Mythbusters show featured a professional singer who broke a wine glass with his voice without any amplification).
It is called DISPLACEMENT of the object....
Answer:
Reaction mechanism has been given below
Explanation:
- Propanoyl chloride contains an electrophilic carbonyl center to give nucleophilic acyl substitution reaction by removing Cl group with a strong nucleophile like methylmagnesium bromide.
- Two equivalent of methyl magnesium bromide react with cabonyl center followed by protonation of negatively charged oxygen atom gives 2-methyl-2-butanol.
- In the first step, nucleophilic acyl substituion occurs. In the second step, nucleophilic addition occurs. In the third step, protonation occurs.
- Reaction mechanism has been shown below.
Answer:
step 2 then step 1 then step 3 then step 4
Explanation:
First boil it. Then identify the situation which is most conducive to boiling
.
While this, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.
The liquid will boil when there is weak intermolecular attraction and low atmospheric pressure.
Steps to be followed:
Pentane at high altitude
Hexane at high altitude
hexane at sea level
hexanol at sea level
