Which of the following statements is TRUE?
Flura [38]

Answer:

c. An ionic bond is much stronger than most covalent bonds

Explanation:

Ionic bonds are interatomic bonds that forms as a result of electrostatic attraction between two ions. For an ionic bond to be formed, one atom must have lost or gained electron from another that is transferring it. Ionic bonds typically form between atoms whose electronegativity differences are far apart.

Ionic bonds are usually stronger than other types of bonds due to the electrostatic attraction between ions.

One very distinct feature about ionic compounds is that they are conductors of electricity in either molten or aqueous. At room temperature, they are solids and contains no mobile ions.

Ivanshal [37]

Answer :By the time thermal equilibrium is attained in the system, ice is completely converted to water.

What is tehrmal equilibrium?

Thermal equilibrium is a situation in which two substances are exactly at the same temperature. That is. Heat is no longer flowing beween the bodies.

Recall that an insulated thermos flask implies that heat does not eneter or leave the system. Heat will flow from the water to the ice untill the both attains the same temperature and the ice is completely converted to water.

Which compound in each pair is more soluble in water?(b) Calcium phosphate or magnesium phosphate
Sidana [21]

<u>larger is the value of </u>Ksp<u> the higher will the solubility of solid in water.</u>

What is called compound?

  • In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
  • When the elements come together, they react with each other and form chemical bonds that are difficult to break.
  • These bonds form as a result of sharing or exchanging electrons between atoms.

The equation for the dissociation of a solid MX in water is given below

MX(s) ⇄ Mⁿ⁺(aq) + Xⁿ⁻ (aq)

Assume s be the solubility of MX in pure water, then the equilibrium concentrations of ions are

[ Mⁿ⁺] = s

[ Xⁿ⁻ ] = s

The expression for the solubility product constant (Ksp) is as follows

Ksp = [ Mⁿ⁺] [ Xⁿ⁻ ]

       = s²

That is, larger is the value of Ksp the higher will the solubility of solid in water.
