Answer:
Fe^3+
Explanation:
The electron configuration for Fe^3+ is; 1s2 2s2 2p6 3s2 3p6 3d5
The electron configuration for Ni^2+ is; 1s2 2s2 2p6 3s2 3p6 3d8
Now it is pertinent to recall that the 3d sublevel has a maximum occupancy of ten electrons. These ten electrons occupy a set of five degenerate orbitals. Having said that, it is clear that Ni^2+ ion will have two unpaired electrons while Fe^3+ will have five unpaired electrons.
Let us also not forget that paramagnetism has to do with the presence of unpaired electrons. That means that maximum paramagnetism refers to the presence of maximum number of unpaired electrons.
Since Fe^3+ has the greatest number of unpaired electrons among the duo, Fe^3+ will exhibit a maximum paramagnetic behavior.
Strong acids are those that dissociate completely into their ions. So the dissociation equation for a strong acid is:
HA → H⁺ + A⁻
It is visible from the equation that the number of moles of hydrogen ions released is equivalent to the number of moles of acid. For a given volume,
[HA] → [H]⁺ + [A]⁻
Thus, the assumption is logical and fairly accurate
Terri and Ernesto should both use geographic maps.

Answer is (1) - N
<em>Explanation:</em>
I think the given chart is electronegativity chart.
Electronegativity is a
value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is
high, then the attraction to the electrons is high unless the attraction to the
electrons is low. </u>
Electronegativity increases from left to right of the periodic table and decreases from up to down.
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).
The electronegativity values for given atoms are
N - 3.0
Na - 0.9
P - 2.1
Pt - 2.2

Answer:
As the use of plants as carbon sinks can be undone by events such as wildfires, the long-term reliability of these approaches has been questioned. Carbon dioxide that has been removed from the atmosphere can also be stored in the Earth's crust by injecting it into the subsurface, or in the form of insoluble carbonate salts (mineral sequestration).
