<h3>The average atomic mass of Iodine : 126.86 amu</h3><h3>Further explanation</h3>
Given
80% 127I, 17% 126I, and 3% 128I.
Required
The average atomic mass
Solution
The elements in nature have several types of isotopes
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% + ... mass isotope n.%
Atomic mass of Iodine = 0.8 x 127 + 0.17 x 126 + 0.03 x 128
Atomic mass of Iodine = 101.6 + 21.42 + 3.84
Atomic mass of Iodine = 126.86 amu
Answer:
(S)-3-methoxy-3-methylbutan-2-ol
Explanation:
In this case, we have an <u>epoxide opening in acid medium</u>. The first step then is the <u>protonation of the oxygen</u>. Then the epoxide is broken to generate the most <u>stable carbocation</u>. The nucleophile (
) will attack the carbocation generating a new bond. Finally, the oxygen is <u>deprotonated</u> to obtain an ether functional group and we will obtain the molecule <u>(S)-3-methoxy-3-methylbutan-2-ol</u>.
See figure 1
I hope it helps!
Answer:
Rinse with vinegar solution several times.
Explanation:
The objective of <em>conditioning</em> equipment is that any impurities are removed before using the glassware in the experiment.
Another reason for conditioning is that any drops left in the glassware are from the intended solution and not water, that way the concentration will not change. However this is why washing thoroughly with soap and water would defeat the purpose of conditioning. It's possible to first wash with soap and water and then rinse with vinegar, but not viceversa.
The correct answer is the last option among the choices given. The color that is bent the least by a prism is red. A white light is a collection of different colors where each color is associated with different wavelength and frequency. When this light is refracted through a lens or prism it splits into separate colors where red is the least bent by a prism.
