The percentage of water of crystallization in blue vitriol (copper sulphate pentahydrate), cuso4.5h2o is 36.07.

The molar weight of blue vitrol (cuso4.5h2o) is:

63.5 + 32+ 4(16) + 5(18) = 249.5 g/mol

The percentage of water of crystallization is :

                   = 5 × 18/249.5

                   = 0.3607 × 100

                   = 36.07%

 

The percentage of water of crystallization in blue vitriol (copper sulphate pentahydrate), cuso4.5h2o is 36.07.

The percentage of water of crystallization in blue vitriol is 36.07%.

M(H₂O) = 2Ar(H) + Ar(O) x g/mol

M(H₂O) = 2 + 16 x g/mol

M(H₂O) = 18 g/mol; molar mass of water

M(CuSO₄·5H₂O) = Ar(Cu) + Ar(S) + 4Ar(O) + 5Mr(H₂O) x g/mol

M(CuSO₄·5H₂O) = 63.5 + 32 + 64 + 90 x g/mol

M(CuSO₄·5H₂O) = 249.5 g/mol; molar mass of copper sulphate pentahydrate

The percentage of water: 5M(H₂O) / M(CuSO₄·5H₂O) x 100%

The percentage of water: 90 g/mol / 249.5 g/mol x 100%

The percentage of water = 36.07%

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 the law of conservation of mass law and not a theory?
Elodia [21]

Answer:

In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.
