Answer:

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.

LenaWriter [7]

According to the illustration, the vanadium (V) oxide would be a catalyst.

<h3>What are catalysts?</h3>

Catalysts are substances that are utilized in reactions that are not themselves consumed in reactions but only speed up the rate of the reactions.

Catalysts speed up the rate of reactions by lowering the activation energy of the reactants.

Sulfur dioxide reacts with oxygen to produce sulfur trioxide. The vanadium (v) oxide is not consumed in the reaction. Thus it only serves as a catalyst.

What is the kinetic energy of 3500 kg bus that is moving at 25 m/s
Bond [772]

Answer:

<h2>1093750 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

v is the velocity

m is the mass

From the question we have

k =  \frac{1}{2}  \times 3500 \times  {25}^{2}  \\  = 1750 \times 625 \\  = 1093750 \:  \:  \:  \:  \:

We have the final answer as

<h3>1,093,750 J</h3>

Hope this helps you
