There are 22.4 liters in 1 mole of O2 so you would need 89.6 liters
Neutrons = 118
<h3>Further explanation </h3>
The elements in nature have several types of isotopes
Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is <em>the average atomic mass of all its isotopes </em>
The most abundant isotope of gold (Au) is isotope Au-197
So the atomic mass of Au = 197
and the atomic number of Au = 79
Atomic mass is the sum of protons and neutrons
Atomic Number (Z) = Atomic mass (A) - Neutrons
Neutrons = A - Z
So neutrons for Au-197 :
Answer: The correct option is D.
Explanation:
In option A:
The names of both the ions are correct but the representation of lithium ion is wrong. Lithium forms a cation and here lithium anion is shown. So, this option is not correct.
In option B:
Here, the representation and name of is written wrong. This ion has a representation of and is named as oxalate. So, this is not correct.
In option C:
The representation of both the ions is correct but the name of is chloride, not chlorate. So. this is not a correct option.
In option D:
The representation and names of both the ions are correct.
Hence, the correct option is D.
