Answer:
b. The splitting of the d-orbitals is smaller in the [Ni(Cl)6]4- complex than in the [Ni(en)3]2+ complex.
Explanation:
The spectrochemical series is an arrangement of ligands in increasing order of their magnitude of crystal field splitting.
Ligands that occurs towards the right in the series are called strong field ligands and they tend to cause a greater magnitude of crystal field splitting. Ligands that occur towards the left hand side in the series are called weak field ligands and they tend to cause a lesser magnitude of crystal field splitting.
Since Cl^- is a weak field ligand, it causes a lesser magnitude of d orbital splitting compared to ethylenediammine (en) which causes a greater magnitude of d orbital splitting.
Hence; the splitting of the d-orbitals is smaller in the [Ni(Cl)6]4- complex than in the [Ni(en)3]2+ complex.
The ecosystem services provided by the each of the given examples are as follows:
- A cornfield in Kansas provides provisioning services.
- Bacteria that decompose waste along the Gulf Coast provides regulating services.
- Ocean currents that keep Pacific Northwest air cool and moist provides regulating services.
- Flower garden at a national landmark provides cultural services.
- Lumber from an oak tree provides provisioning services.
- Animals that eat seeds and then spread the seeds through their waste regulating services.
<h3>Ecosystem services</h3>
Ecosystem services are defined as the benefits derived by man from the surroundings ecosystems.
<h3>Categories of ecosystem services</h3>
The four categories of ecosystem services are:
- regulating services,
- provisioning services,
- cultural services, and
- supporting services
A cornfield in Kansas provides provisioning services.
Bacteria that decompose waste along the Gulf Coast provides regulating services.
Ocean currents that keep Pacific Northwest air cool and moist provides regulating services.

Answer:
C. The model shows beta decay, whichis not tyoe of nuclear fission
Answer:
pOH = 9.
Explanation:
The inverse relationship between the pH and pOH of any given solution can be written as:
pH = 14 - pOH
Or conversely:
pOH = 14 - pH
With the above information in mind we can <u>use the given pH to calculate the pOH</u>:
pOH = 14 - pH
pOH = 14 - 5
pOH = 9
Thus, black coffee has a pOH of 9.
