For the reaction o(g) + o2(g) → o3(g) δh o = −107.2 kj/mol given that the bond enthalpy in o2(g) is 498.7 kj/mol, calculate the
Aneli [31]
The reaction;
O(g) +O2(g)→O3(g), ΔH = sum of bond enthalpy of reactants-sum of food enthalpy of products.
ΔH = ( bond enthalpy of O(g)+bond enthalpy of O2 (g) - bond enthalpy of O3(g)
-107.2 kJ/mol = O+487.7kJ/mol =O+487.7 kJ/mol +487.7kJ/mol =594.9 kJ/mol
Bond enthalpy (BE) of O3(g) is equals to 2× bond enthalpy of O3(g) because, O3(g) has two types of bonds from its lewis structure (0-0=0).
∴2BE of O3(g) = 594.9kJ/mol
Average bond enthalpy = 594.9kJ/mol/2
=297.45kJ/mol
∴ Averange bond enthalpy of O3(g) is 297.45kJ/mol.

1. Identify the type of ecosystem service being provided in each of the following
Wittaler [7]

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.

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.
