Consider the following oxidation-reduction reaction: 2fe3+(aq) + 2hg(l) + 2cl−(aq) → 2fe2+(aq) + hg2cl2(s). indicate the oxidizing agent and the reducing agent.

The reducing agent is Hg (mercury) and the oxidixing agent is Cl (chlorine)

Explanation:

first find the oxidation charges of each of the different ions. All elements that are alone have a charge of 0. As you compare the reactants and products we can see that the chargers of Hg and Cl have changed.

Hg went from a charge of 0 to a charge of +1

Cl went from a charge of 0 to a charge of -1

remember when a substance gains electrons it is reducing and when a substance is losing electrons it is oxidizing.

use the acryonm

Oxidizing Is Losing

RIG

Reducing Is Gaining

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

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 .
