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.

Solid potassium chlorate (kclo3) decomposes into potassium chloride and oxygen gas when heated. how many moles of oxygen form wh
IrinaVladis [17]

Answer:

  • <u>0.665 mol of O₂.</u>

Explanation:

<u>1. Molecular chemical equation:</u>

  • 2 KClO₃(s) → 2 KCl(s) + 3 O₂(g)

<u>2. Mole ratios:</u>

  • 2 mol KClO₃ : 2 mol KCl : 3 mol O₂

<u>3. Number of moles of KClO₃</u>

  • Number of moles = mass in grams / molar mass

  • Molar mass of KClO₃ = 122.55 g/mol

  • Number of moles of KClO₃ = 54.3 g / 122.5 g/mol ≈ 0.44308 mol

<u>3. Number of moles of O₂</u>

As per the theoretical mole ratio 2 mol of KClO₃ produce 3 mol of O₂, then set up a proportion to determine how many  moles of O₂ will be produced from 0.44038 mol of KClO₃.

  • 3 mol O₂ / 2 mol KClO₃ = x / 0.44038 mol KClO₃

  • x = (3 / 2) × 0.44308 mol O₂ = 0.6646 mol O₂

Round to 3 significant figures: 0.665 mol of O₂ ← answer

Write a neutralization reaction for each acid and base pair.a. HI(aq) and NaOH(aq)b. HBr(aq) and KOH(aq)c. HNO3(aq) and Ba(OH)2(
AVprozaik [17]

Answer:

a. HI(aq)+NaOH(aq) → H2O(l)+NaI(aq)

b. HBr(aq) +KOH(aq) → H2O(l)+KBr(aq)

c. HNO3(aq)+Ba(OH)2(aq) → BaNO3(aq)+H2O(aq)

D. HClO4(aq)+Sr(OH)2(aq) → SrClO4(aq)+H2O(aq)

Explanation:

In a neutralization reaction, an acid and a base react to form water and salt and involves the combination of H+ ions and OH- ions to generate water.

In this case, the atoms have charge positive and negative, the only thing we have to do is to change in the products taking account that positive with negative an vice-versa.

                         H+I-(aq)+Na+OH-(aq) → H+2O-(l)+Na+I-(aq)
