Answer from: RoxanneDuartee

B. A covalent bond in which the electrons are shared equally .

A. "A covalent bond in which the electrons are shared unequally" is incorrect. Such a bond would be a polar covalent bond

C. "A covalent bond formed between a metal and a non-metal" is incorrect. Such a bond would be an ionic bond.

D. "A covalent bond formed between two different elements" is incorrect. We would need to know the elements before we could decide the type of bond.

B. A covalent bond in which the electrons are shared equally

Explanation:

Covalent bonds are formed by sharing of electrons between non metals.

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the unequal sharing of electrons between the atoms. Example:

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the equal sharing of electrons between the atoms. Example: H_2

Answer from: Quest

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
