Answer : The correct option is, electrons are not shared equally between atoms.

Explanation :

Polar covalent bond : It is a type of chemical bond in which a pair of electrons are not shared equally between the two atoms.

In polar covalent bond, the electrons are not shared equally because one atom spends more time with the electrons than the another atom. In this, one atom has more tendency to pull an electron than the other atom.

For example : $H_2O$ is an example of polar covalent bond. In water molecule, oxygen spends more time with the electron than the hydrogen and oxygen carries a partial negative charge.

Which correctly describes the reaction between potassium and excess water?

nika2105 [10]

Balanced chemical reaction: 2K(s) + 2H₂O(l) → 2KOH(aq) + H₂(g).

KOH is inorganic compound p<span>otassium hydroxide, a strong base.
H</span>₂ is hydrogen gas.
In balanced chemical reaction number of atoms on both side of chemical reaction must be same. There are two potassium atoms, four hydrogen atoms and two oxygen atoms on both side of reaction.

The Ksp for CaF2 is 3.9 x 10-11 at 25oC. What is the solubility?

nevsk [136]

We have to know the solubility of CaF₂.

The solubility of CaF₂ is: (c) 2.1 x 10-4 Molar

The general expression of solubility product of any sparingly soluble salt (having solubility S) with formula $A_{x} B_{y}$ is: $x^{x} y^{y} S^{x+y}$ .
