Answer:
Nonpolar covalent bonds involve two atoms that have equal electonegativity whereas polar covalent bonds involve two atoms that are unequal in their electronegativity.
Explanation:
Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.
A covalent bond is a force that joins two atoms of non-metallic elements to form a molecule. Atoms share pairs of electrons from their most superficial layer (called the valence layer) to achieve the stability of the molecule that has been formed with the bond and thus comply with the octet rule.
On the other side, electronegativity refers to the tendency of the atom of a given element to attract electrons.
So, the covalent bond between two atoms can be polar or nonpolar.
Polarity depends on the difference in electronegativity of the joining elements. The greater the electronegativity difference, the greater the polar character of the bond. The most electronegative element will be the one that most strongly attracts the shared electrons, then a negative partial charge will be generated on said element, while a positive partial charge will be generated on the other element (less electronegative).
Finally, nonpolar covalent bonding occurs when pairs of electrons are shared between atoms that have the same or very similar electronegativity, favoring an equitable distribution of electrons.
In summary, the correct answer is: Nonpolar covalent bonds involve two atoms that have equal electonegativity whereas polar covalent bonds involve two atoms that are unequal in their electronegativity.

What are triangle inequalities?The triangle inequality theorem explains the connection between a triangle's three sides. This theorem states that for any triangle, the sum of the lengths of the first two sides is always greater than the length of the third side.
The vertices must be colinear, which means that the three sides form a line segment rather than a triangle if the length of one side equals the total of lengths of the other two sides. The triangle inequality is what we refer to here. Any triangle side must be shorter than the sum of the other two sides.
Therefore, the correct option is A.) Michael’s dock would be closed because the angle opposite is smaller.

Hydrogen selenide (H2Se) reacts with water according to the following equation. H2Se H2O → SeH– H3O In three to five sentences, identify the acid, base, conjugate acid, and conjugate base in this reaction. Use patterns in the periodic table to explain why the substances you identified acted as the acid and the base in this reaction.
Taking into account the Brønsted-Lowry acid-base theory:
H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.
The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.
According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.
So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.
In other words, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:
acid + base ⇄ conjugate base + conjugate acid
In this case, you know:
H₂Se + H₂O → SeH⁻ + H₃O⁺
H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.
So, H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.
