Iodine, i2, has many uses, including the production of dyes, antiseptics, photographic film, pharmaceuticals, and medicinal soaps. it forms when chlorine, cl2, reacts with iodide ions in a sodium iodide solution. which of the following half-reactions for this oxidation‑reduction reaction describes the oxidation, and which one describes the reduction? cl2 + 2e‒ → 2cl‒ 2i‒ → i2 + 2e‒

Explanation:

Oxidation-reduction reaction is the simulaneous oxidation and reduction of the substances and is represented by two half-reactions.

The oxidation half-reaction is the loss of electrons, with the consequent increase in the oxidation state by the oxidized substance.

In this case, the process that shows the loss of electrons is:

That reaction shows:

On the other hand, the reduction half-reaction is the gain of electrons, with the consequent reduction of the oxidation state by the reduced substance.

In this case, the process that shows the gain of electrons is:

That reaction shows:

Summary:

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
