Zinc has an average atomic mass of 65.37 amu. Jack is trying to figure out what the most abundant isotope of zinc is, but he doesn't have access to the internet, so the average atomic mass is the only information he has. Jack decides to made an educated guess as to the most abundant isotope of zinc by assuming there are only two isotopes of zinc. If Jack assumes there are only two isotopes of Zn, what he be most likely to decide is zinc's most abundant isotope?
Question 5 options:

Zinc-64


Zinc-65


Zinc-68


Zinc-66

Answers

Zinc's most abundant isotope : Zinc-65

Further explanation

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Atomic mass is the average atomic mass of all its isotopes

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu

Mass atom X = mass isotope 1 . % + mass isotope 2.%

To decide zinc's most abundant isotope, then choose the closest mass number

or we can check the difference with the average mass number, if the value is the smallest, then that isotope has the largest abundant

Zinc-64

[tex]\tt \dfrac{65.37-64}{65.37}=0.021[/tex]

Zinc-65

[tex]\tt \dfrac{65.37-65}{65.37}=0.005[/tex]

Zinc-68

[tex]\tt \dfrac{68-65.37}{65.37}=0.04[/tex]

Zinc-66

[tex]\tt \dfrac{66-65.37}{65.37}=0.009[/tex]

The closest = Zinc-65(the smallest)

A 0.5
B 2.0
C 4.0
D 32.0

What does it mean for an element to be oxidized?

A. The element is a spectator ion in a chemical reaction.

B. The element has gained one or more electrons in a reaction.

C. The element has lost one or more electrons in a reaction.

D. The element has bonded to another element with opposite charge​

Answers

Answer:

B

Explanation:

Oxidation occurs when an atom molecule or ion loses one or more electrons in a chemical reaction when oxidation occurs the oxidation state of the chemical species increases oxidation doesn't necessarily involve oxygen originally the term was used when oxygen caused electron loss in a reaction hope this helped. :)

An element is oxidized when It has loses one or more electrons in a chemical reaction. Therefore, Option (C) is correct.

What is Oxidation ?

The loss of electrons, gain of oxygen or loss of hydrogen will be considered as Oxidation.

The gain of electrons, loss of oxygen or gain or hydrogen will be considered as the Reduction.

Rusting is one of the popular example of oxidation.

Therefore, An element is said to be oxidized when It has lost one or more electrons in a reaction.

Hence , Option (C) is correct.

If the average atomic mass is 39.948amu, which isotope is more abundant?

Answers

Answer:

It depends on which element you are talking about. I appears that no element has an average atomic mass of that number. So, for the question, if it assumes that there are two isomers with 39 amu and 40 amu, then the 40 amu one would be more abundant. But again, there are different possible isotopes and I can't tell what the question wants.
