Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.
The oxidation number of Fe in Fe(NO3)2 is +3.
The detriment of these advancements to the Earth is that: the growing population is taxing Earth's resources which could lead to the extinction of many species.
<h3>The effect of science and technology.</h3>
Various scientific discoveries and technological advances around the world have led to an exponential increase in Earth's population with no end of the growth in sight.
In conclusion, we can infer and logically deduce that the statement which best describes how these advancements are detrimental to the Earth is that the growing population is taxing Earth's resources and this may likely lead to the extinction of many species of organisms.

Magnetic reversals
Explanation:
A change in the orientation of the earth's magnetic field is known as magnetic reversals.
During a magnetic reversal, the geographic south pole aligns with the magnetic north.
The geographic north pole aligns with the magnetic south.
- The geomagnetic field of the earth is produced by the movement of metallic minerals in the outer core.
- This streaming of metallic minerals generals electric current that induces a magnetic field.
