A. hydroxide is the answer
Answer:
A
Explanation:
Iron has the ground state electronic configuration [Ar]3d64s2
Fe2+ has the electronic configuration [Ar]3d6.
In an octahedral crystal field, there are two sets of degenerate orbitals; the lower lying three t2g orbitals, and the higher level two degenerate eg orbitals. Strong field ligands cause high octahedral crystal field splitting, there by separating the two sets of degenerate orbitals by a tremendous amount of energy. This energy is much greater than the pairing energy required to pair the six electrons in three degenerate orbitals. Since CN- is a strong field ligand, it leads to pairing of six electrons in three degenerate orbitals
Answer:
<h3>The answer is kinetic energy</h3>
Explanation:
<h2>The answer is Kinetic Energy because take for an example, When an apple falls from the tree to the ground, its energy of position is then made into kinetic energy, the energy of motion, as it falls to the ground. </h2>
