Which statement describes the redox reaction that occurs when an object is electroplated? * 1 point A. It is spontaneous and requires an electric current. B. It is spontaneous and produces an electric current. C. It is nonspontaneous and requires an electric current. D. It is nonspontaneous and produces an electric current.

C. It is nonspontaneous and requires an electric current.

Explanation:

Electroplating refers to the process of coating a metal on the surface of another metal. Electroplating may be carried out to improve the properties of a metal or to preserve it from corrosion.

Electroplating involve the process of electrolysis. In electrolytic cells, electrical energy causes nonspontaneous reactions to occur in a process known as electrolysis. Electrolytes are decomposed during electrolysis by the passage of direct current to form ions.

The entire process of electrolysis is non spontaneous. It requires the input of electric electric current. This is achieved by connecting a battery to supply energy to drive the non spontaneous process.

the movie was based there, and all the animals and characters are native.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
