The water cycle iss a process which helps to circulate and replenish water on earth.

<h3>What is hydrology?</h3>

Hydrology is the scientific study of water bodies , the changes that occur in them as well as the various features and behavior of water bodies such as oceans and rivers.

Water circulation created by prevailing wind systems. The Gulf Stream is an example up of the Coriolis effect.

The length of open sea over which wind can blow steadily to create waves is called fetch.

Salinity is the amount of dissolved salt in a liquid

The distance from the crest of one wave to the crest of another is called wavelength

Water circulation created by differences in density deepwater currents

Energy is what moves forward and through a wave.

The cyclical process of the changing state and movement of water around the Earth through evaporation, condensation, and precipitation is called water cycle.

As the amount of salt in water increases, the density of the water increases.

The type of energy possessed by moving water is called kinetic energy.

The rising of ocean water bringing nutrients up from the deep us called upwelling.

Therefore, the water cycle helps to circulate and replenish water on earth.

The compound cisplatin, Pt(NH3)2Cl2, has been studied extensively as an antitumor agent.___K2PtCl4 (aq) + ___NH3 (aq)  ___Pt(NH
Lostsunrise [7]

Mass of cisplatin can be made : 144.6 g

<h3>Further explanation</h3>

Given

Reaction(unbalanced)

K2PtCl4 (aq) + ___NH3 (aq)  ___Pt(NH3)2Cl2 (s) + ___KCl (aq)

200 g of K2PtCl4

Required

mass of cisplatin  Pt(NH3)2Cl2

Solution

Balanced equation

K₂PtCl₄ (aq) + 2NH₃ (aq) ⇒Pt(NH₃)₂Cl₂ (s) + 2KCl (aq)

mol of K₂PtCl₄(MW=2.39+195+4.35.5=415 g/mol) :

mol = mass : Mw

mol = 200 : 415

mol = 0.482

From equation, mol ratio K₂PtCl₄ : Pt(NH₃)₂Cl₂ = 1 : 1, so mol Pt(NH₃)₂Cl₂ = 0.482

Mass of cisplatin Pt(NH₃)₂Cl₂(MW=195+2.14+6.1+2.35.5=300 g/mol) :

mass = mol x MW

mass = 0.482 x 300

mass = 144.6 g

Why are electrons restricted to specific orbitals?
rodikova [14]
The answer lies in the concept of quantum mechanics. Every single electron of an atom has its own unique set of quantum numbers. It is stated in the Pauli Exclusion principle that no two electrons would have the same quantum numbers. That is why each electron occupies a specific orbital. In addition to the Pauli Exclusion Principle, the other laws and principles that help set the quantum numbers are the Aufbau Principle and the Hund's rule.
