What do you need help with
Explanation:
Answer:
2%
Explanation:
Original mass of water in glass = 10 ounces
amount that evaporates each day = 0.01 ounce
number of days = 20 days
Total amount that evaporated = 0.01 x 20 = 0.2 ounce
percentage of water that evaporated during this period = 0.2/10 x 100
= 2%
<em>Hence, the percentage of the original amount of water evaporated during this period is 2%</em>
The NMR spectroscopy will be used for distinguishing a sample of 1,2-dichloropropane from 1,2-dibromopropane.
A spectroscopic method for observing the local magnetic fields surrounding atomic nuclei seems to be nuclear magnetic resonance spectroscopy, also referred to as magnetic resonance spectroscopy as well as NMR spectroscopy.
The identification and study of organic molecules benefit greatly from nuclear magnetic resonance (NMR) spectroscopy. This type of spectroscopy has a straightforward underlying theory. Numerous atom types' nuclei behave like small magnets and frequently align themselves in magnetic fields.
Therefore, the NMR spectroscopy will be used for distinguishing a sample of 1,2-dichloropropane from 1,2-dibromopropane.
