Explanation:
The given equation is as follows.

Reactants are the species present on the left hand side of a chemical equation.
Products are the species present on the right hand side of a chemical equation.
Whereas coefficients are the number present in front of formulas.
Therefore, in the given reaction equation, matched terms are as follows.
- Reactant is

- Product is AB.
- Coefficient is 2.
The 1996 NHTSA study, Crash Outcome Data Evaluation System
(CODES), related traffic flow and medicinal accounts in seven states to measure
entire costs of wound from motor vehicle crashes. The research originate that the
mean inpatient costs for crash fatalities who were not using safety belts
were 55 percent <span>higher than for those who were belted.</span>
Answer:
CN^- is a strong field ligand
Explanation:
The complex, hexacyanoferrate II is an Fe^2+ specie. Fe^2+ is a d^6 specie. It may exist as high spin (paramagnetic) or low spin (diamagnetic) depending on the ligand. The energy of the d-orbitals become nondegenerate upon approach of a ligand. The extent of separation of the two orbitals and the energy between them is defined as the magnitude of crystal field splitting (∆o).
Ligands that cause a large crystal field splitting such as CN^- are called strong field ligands. They lead to the formation of diamagnetic species. Strong field ligands occur towards the end of the spectrochemical series of ligands.
Hence the complex, Fe(CN)6 4− is diamagnetic because the cyanide ion is a strong field ligand that causes the six d-electrons present to pair up in a low spin arrangement.
