The formula for an isotope of oxygen with nine neutrons, including the mass number and the atomic number is 17/8 O.
<h3>What is an isotope?</h3>
Isotope is any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.
This means that atoms of isotopes will have the same atomic number but a different mass number.
According to this question, an isotope of oxygen has 9 neutrons. If oxygen has an atomic number of 8, the formula of this particular isotope is as follows: 17/8 O.

Madison Boulder is made of fine-grained feldspar and larger quartz crystals that welled up under great pressures from a molten mass deep in the earth over 200 million years ago. Upon cooling, the molten rock hardened. Over the millions of intervening years softer materials on the earth's surface were removed by erosion from wind and water. Not so with the granite of New Hampshire, the Granite State!
As recently as 1835, geologists believed that huge boulders like Madison Boulder isolated in their surroundings had been washed to their present locations by great floods which are said to have occurred in ancient times. Today, it is believed that these large boulders, or "erratics," were moved various distances during the last ice age.
Most authorities trace Madison Boulder to the Whitton or White ledges 12.5 and 4 miles respectively, to the northwest. However, a few maintain that the boulder so closely resembles one of the four types of rock that form Mount Willard in Crawford Notch, twenty-four miles to the nothwest, that the ice sheet must have brought it from there. Madison Boulder lies on "glacial drift," unsorted sediments left by the retreating ice sheet.
Data:
Explanation:
The rate constant as a function of the temperature can be expressed using the Arrhenius equation, as follows,
Then, find a value for the constant A, according to the data given in the exercise,
As the rate constant has units then, the reaction corresponds to one of first order. Then, the reaction corresponds to:
Which tell the amount of mass (mol) is produced by second per unity of volume.
Answer:
If the reaction goes twice fast, the reaction rate corresponds to,
The expression above can be reduced to:
Replacing k(T) in order to obtain the temperature T,
Replacing all values,
As the H bond of the butanol is more effective and strong than Van der Waals forces of the ether the surface tension in alcohol is more intensive.
So the correct answer is e)
