Answer:

The correct answer is "D. The difference in their electronegativities is greater than 1.7"

Explanation:

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

So, this type of bond consists of the attraction of atoms with electric charges of different signs, that is, the bond is established when atoms of low electronegative elements (metals) are bonded with atoms of highly electronegative elements (nonmetals).

So you can say that atoms of electronegativity difference equal to or greater than 1.7 participate in this type of bond (with its exceptions).

The correct answer is "D. The difference in their electronegativities is greater than 1.7"

What force on Earth can affect the pull of gravity?

MakcuM [25]

Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.

Adding which of the following substances will decrease the solubility of calcium chloride in water: CaCl2(s) Ca2+(aq) + 2 Cl–(aq

Korvikt [17]

Answer:

Option b. Sodium chloride.

Explanation:

Consider the dissociation equilibrium of $\rm CaCl_2 \; (s)$ in water:

$\rm CaCl_2 \; (s) \rightleftharpoons Ca^{2+} \; (aq) + 2\; Cl^{-}\; (aq)$ .

By the Le Chatelier's Principle, increasing the concentration of either product will shift the equilibrium to the left. Some $\rm CaCl_2 \; (s)$ that was initially dissolved will precipitate out of the solution. This effect is called the common-ion effect.

For this $\rm CaCl_2 \; (s)$ solution, the products of dissociation are

$\rm Ca^{2+}$ ions, and
$\rm Cl^{-}$ ions.

Adding either to the solution will trigger the common-ion effect and reduce the solubility of $\rm CaCl_2 \; (s)$ .

In the two choices,

Sodium chloride $\rm NaCl$ will add $\rm Na^{+}$ and $\rm Cl^{-}$ ions to the solution.
Sodium fluoride $\rm NaF$ will add $\rm Na^{+}$ and $\rm F^{-}$ ions to the solution.

$\rm NaCl$ contains $\rm Cl^{-}$ ions. It is capable of triggering the common-ion effect. However $\rm NaF$ contains neither $\rm Ca^{2+}$ ions nor $\rm Cl^{-}$ ions. It will not trigger the common-ion effect.
