The appropriate answer is D. volatility. Volatility refers to the susceptibility of liquids to vaporize. Perfume is liquid when applied but because of volatility, it has a tendency to vaporize and so it will convert to a gas and diffuse across the room. The process by which a liquid changes to a vapor is called evaporation.

The ksp of copper(ii) carbonate, cuco3, is 1.4 × 10-10. calculate the molar solubility of this compound.
mafiozo [28]
As,
                              CuCO₃    ⇆  Cu²⁺  +  CO₃²⁻
So,
                             Kc  =  [Cu²⁺] [CO₃²⁻] / CuCO₃
Or,
                             Kc (CuCO₃)  =  [Cu²⁺] [CO₃²⁻]
Or,
                             Ksp  =  [Cu²⁺] [CO₃²⁻]
As,
Ksp  = 1.4 × 10⁻¹⁰
So,
                            1.4 × 10⁻¹⁰  =  [x] [x]
Or,
                             x²  =  1.4 × 10⁻¹⁰ 
Or,
                             x  =  1.18 × 10⁻⁵ mol/L
To cahnge ito g/L,
                             x  =  1.18 × 10⁻⁵ mol/L × 123.526 g/mol

                   
         x  =  1.45 × 10⁻³ g/L

\bold{\huge{\underline{ Solution }}}

<h3><u>Basic </u><u>Characteristic </u><u>of </u><u>acids </u></h3>

  • Acids are sour in taste
  • Acid turns blue litmus paper or solution into red litmus paper or solution
  • Acids are good conductor of electricity because it dissociate into cation in aqueous solution
  • Acids classified into edible acids and non edible acids. Non edible acids are very hazardous
  • Generally, All acids are soluble in water
  • Acids have PH smaller than 7

<u>Arrhenius </u><u>definition </u><u>of </u><u>acids </u><u>:</u><u>-</u>

According to Arrehinus,

  • Acids are those substances which when dissolve in water given H positive ions . Then, this hydrogen ions combine with water to form H30 + ions

<u>Second </u><u>definition </u><u>of </u><u>Acids </u><u>was </u><u>given </u><u>by </u><u>Bonsted </u><u>Lowry </u><u>:</u><u>-</u>

According to Bonsted Lowry

  • Acids are the proton donors that is when acids dissociate into water gives hydrogen ions that is H+ ions

<u>3rd </u><u>definition </u><u>was </u><u>given </u><u>by </u><u>Lewis </u>

According to Lewis

  • Acids are those substances which have the ability to accept a pair of electrons .

Example of Acids

  • HNO3 :- Nitric acid
  • H2SO4 :- Sulfuric acid
  • HCl :- Hydrochloric acid

<h3><u>Basic </u><u>characterists </u><u>of </u><u>bases </u></h3>

  • Bases are bitter in taste
  • Bases turns red litmus paper into blue litmus paper or solution
  • Bases are also good conductor of electricity because on dissociation it produces anion in aqueous solution
  • Bases are also good conductor of electricity
  • When bases are soluble in water then they are known as alkaline base
  • Bases have PH greater than 7

<u>Arrehinus definition of bases :-</u>

According to Arrehinus ,

  • Bases are those substances which when dissolve in water produce OH negative ions that is hydroxide ions

<u>Bonsted Lowry definition </u>

According to Bonsted Lowry

  • Bases are the proton donors as they produce OH negative ions in dissociation in aqueous solution

<u>Lewis </u><u>definition </u>

According to Lewis

  • Acids are those substances which have the ability to lose electrons that is they are electron donors.

Example of bases

  • Ca(OH)2 :- Calcium hydroxide
  • NaOH :- Sodium hydroxide
  • KOH :- Potassium hydroxide

[ Note :- There are so many Lewis acids and bases but they are not Arrhenius or Lowry acids or bases ]

<h3><u>Basic </u><u>characteristic </u><u>of </u><u>salt </u></h3>

  • Salts are the ionic compounds which are composed of acids and bases that cation and anion
  • Salts are generally found in oceans and seas in the forms of crystals
  • As they are composed of acids and bases so they are neutral in nature but the salt of strong acid or weak base is acidic in nature or vice versa
  • Salts are also good conductor of electricity as they form ionic bond
  • Generally, All salts are soluble in water.
  • The PH of common Salt is 7

Example of salts

  • NH4Cl :- Ammonium chloride
  • CuSO4 :- Copper sulphate
  • NaCl :- Sodium chloride

What energy sources boil the water in geothermal energy
GREYUIT [131]
The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.
