Answer:
a) nitrogen
b) nitrogen =5
Oxygen = 6
Fluorine =7
Explanation:
Usually, if we have two or more elements in a compound, the central atom in the compound is the atom having the least value of electro negativity.
If we consider fluorine, oxygen and nitrogen; nitrogen is the least electronegative of the trio hence it should be the central atom of the triatomic molecule.
The number of valence electrons on the valence shell of each atom is shown below;
nitrogen =5
Oxygen = 6
Fluorine =7

Answer:
b. Ag ( s )
d. Ni ( s )
= 2.97 V
Explanation:
The reduction potentials for the given four (4) electrodes are:
In the first cell:
In the second cell:
Since the cells are connected in series :
Thus; Metal plated in the first cell = Ag
Metal plated in the second cell = Ni
The total potential =
= (0.80 + 1.66 ) V - (0.25 +0.76 ) V
= 2.97 V
Answer:
Rb+
hope it's right:)
