Answer:
For 31 P NMR spectra
<u>low temperature </u>
there is two types of 19f seen in low temperature and they are
- one at equitorial
- one at axial
therefore in low temperature the 31p couples with the two types of 19F seen ( 
to form a triplet and this couples more with 
to form a doublet. i.e. one (1) peak
<u>High temperature </u>
At High temperature The exchange is fast here therefore the 31p spectra sees all 19p at once and in the same environment leading to the formation of one (1) peak
For 19 P NMR spectra
<u>low temperature </u>
In low temperature 
is fixed and the environment where 
is the same hence a peak is formed and another peak is formed by that makes the number of peaks = 2 peaks
<u>High temperature </u>
In high temperature exchange very fast therefore one peak is formed for all, since the fast exchanges makes NMR machine to take an average and produce just one peak for all

Answer:
A job hazard analysis is a technique that focuses on job tasks as a way to identify hazards before they occur. It focuses on the relationship between the worker, the task, the tools, and the work environment. After uncontrolled hazards are identified, take action to eliminate them or reduce risk.

Answer:
The term you are looking for is recovery. The process of recovering refrigerant is to remove some or all the refrigerants of a system and deposit it in an external storing for further processing or storage. This recovered refrigerant won´t be used again in the system in any near time period.
If the refrigerant is removed to be instantly processed and cleaned to be reutilized in the same system, this action is known as recycling.
