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.
Answer:
9 protons
Explanation:
By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

Answer:
it is grown in grassland.
The answer is the option (3) The geometric shape of a CH4 molecule
distributes the charges geometrically. the CH4 is a tetrahedral with the
Carbon atom in the center and the four H atoms in the vertices of the
tetrahedral. The C-H bond angles are all identical which makes the
molecule perfectly symmetrical and so any dipolar moment will cancel
making the molecule non polar.
<u>Given:</u>
EMF = 0.88 V
Strength of magnetic field, B = 0.075 N/A-m
Velocity, v = 4.20 m/s
<u>To determine:</u>
The length of wire, L
<u>Explanation:</u>
The EMF is related to strength of the magnetic field B as:
EMF = L*B*v
L = EMF/B*v = 0.88/0.075*4.20 = 2.79 m
Ans: The length of the wire is around 2.8 m
