Answer:
-1043,8 KJ
Explanation:
Hello!
It is necessary to accommodate the reactions to get the reaction of my interest.
Reaction A reverses what modifies its energy in its sign (+72.6 KJ).
Reaction B doubles, which also doubles its energy (-514.4 KJ x 2).
Reaction C reverses what modifies its energy in its sign (-87.6 KJ).
By sum of the energies I get the energy of the global reaction.

Solution :
A pentagonal bipyramidal is a bond structure where the bond angle that surrounds an atom is not identical. Different bond angles are different. It has one central atom having seven ligands at the corners of the pentagonal bipyramidal.
a). The shape of the molecule that have 7 bonding domains is called the pentagonal bipyramidal. For example take the case of .
The structure of the molecule is attached below.
b). The bond angles that can be possible between all the adjacent atoms are 72 degrees and 90 degrees.
c). The lone pair is represented by E and the 6 bonding domains, the geometry is the pentagonal pyramidal, that is in the case of .
d). With two lone pairs, which is represented by E and as many as 5 bonding domains, the geometry is described as pentagonal planar. For example,
