Given the electrochemical cell reaction: Zn(s) + Ni2+ (aq) → Zn2+ (aq) + Ni(s)

Which species is the reducing agent?

Explanation:

Charge flow occurs in solution by ions carrying positive or negative charges. Oxidation always occurs at the Anode and Reduction always at the Cathode. Electron flow through the metal is from the anode to the cathode.

Explanation:

For a Galvanic - Voltaic Cell, electron flow is from the anode to the cathode. The following diagram gives reactions at electrodes and direction

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.
