Answer:
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Answer:
dispersion, dipole-dipole, and hydrogen bonding
Explanation:
The pictured compound is an amine. Amines have high boiling points. Amines have such high boiling points because they posses about three different kinds of intermolecular interactions, viz; hydrogen bonds, dispersion forces and dipole-dipole interactions.
The dipole interactions and hydrogen bonds arise from the fact that the N-H bond is polar. Also recall that a hydrogen bond is formed when hydrogen is bonded to an electronegative element. Hydrogen bonds lead to significant intermolecular association and high boiling points.
Hence the three kinds of intermolecular forces present in the pictured compound are; hydrogen bonding, dipole interactions and dispersion forces.
Fluorine
Explanation:
F- has the lowest ionisation energy
In order to determine if a reactant is in excess or limiting, we must first know the required amount of reactants. This is referred to as the stoichometric amount of reactant, and it is obtained from the chemical equation.
From the equation, we form a ratio of the reactants. The reactant supplied in excess of that ratio is the excess reactant, while the other is the limiting reactant.
Answer:
The answer to your question is A. Ionic
Explanation:
There are 3 kinds of bonds in chemistry
a) Ionic bonds are the bonds between a metal and a nonmetal. Metals lost their electrons and nonmetals gain them. These bonds are the strongest so the melting and boiling points are the highest of all.
b) Covalent bonds are bonds between two nonmetals. The elements share electrons so these bonds are not as stronger as Ionic bonds, the melting and boiling points are high.
c) Metallic bonds are among metals and have high melting and boiling points.
