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.

Why is steam distillation prefered over fractional distillation for the extraction of essencial oils?​
frez [133]

Answer:

Because , the advantage of steam distillation over simple distillation is that the lower boiling point reduces decomposition of temperature-sensitive compounds. Steam distillation is useful for the purification of organic compounds, although vacuum distillation is more common

A heat pump is used to heat a house in the winter and to cool it in the summer. During the winter, the outside air serves as a l
elixir [45]

Answer:

T_{C} = -4.2°C

T_{H} = 49.4°C

Explanation:

A Carnot cycle is known as an ideal cycle in thermodynamic. Therefore, in theory, we have:

|\frac{Q_{C} }{Q_{H} }| = \frac{T_{C} }{T_{H} }

Similarly,

|Q_{H}| = |Q_{C}| + |W_{S}|

During winter, the value of |T_{H}| = 20°C = 273.15 + 20 = 293.15 K and |W_{S}| = 1.5 kW. Therefore,

|Q_{H}| = 0.75(T_{H} -  T_{C})

Similarly,

|\frac{W_{S} }{Q_{H} }| = 1 - \frac{T_{C} }{T_{H} }

1.5/0.75*(293.15-T_{C}) = 1 - (T_{C}/293.15

Further simplification,

T_{C} = -4.2°C

During summer, T_{C} = 25°C = 273.15+25 = 298.15 K, and |W_{S}| = 1.5 kW. Therefore,

|Q_{C}| = 0.75(T_{H} -  T_{C})

Similarly,

|\frac{W_{S} }{Q_{C} }| = \frac{T_{H} }{T_{C} } - 1

1.5/0.75*(T_{H} - 298.15) = (T_{H}/298.15

Further simplification,

T_{H} = 49.4°C

An unknown concentration of sodium thiosulfate, Na2S2O3, is used to titrate a standardized solution of KIO3 with excess KI prese
Maru [420]

Answer: The molarity of Na_2S_2O_3 is 0.108 M

Explanation:

KIO_3+5KI+3H_2SO_4\rightarrow 3K_2SO_4+3H_2O+3I_2

2Na_2S_2O_3+I_2\rightarrow Na_2S_4O_6+2NaI

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}    

\text{Moles of }KIO_3=\frac{0.0131mol/L\times 21.55}{1000}=2.8\times 10^{-4}mol

1 mole of KIO_3  produces = 3 moles of   I_2

2.8\times 10^{-4} moles of KIO_3 produces = \frac{3}{1}\times 2.8\times 10^{-4}=8.4\times 10^{-4} moles of I_2  

Now 1 mole of I_2 uses = 2 moles of Na_2S_2O_3

8.4\times 10^{-4} moles of I_2 uses =  \frac{2}{1}\times 8.4\times 10^{-4}=1.69\times 10^{-3}  moles of Na_2S_2O_3

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution in L}}=\frac{1.69\times 10^{-3}\times 1000}{15.65}=0.108M

The molarity of Na_2S_2O_3 is 0.108 M
