Answer: Option (D) is the correct answer.

Explanation:

A catalyst is defined as the substance that lowers the activation energy of a chemical reaction without itself getting consumed so that there will be increase in rate of reaction.

As catalyst lowers the activation energy so, reactant molecules with lower energy also participates in the reaction. Hence, morr collisions occur due to which there is rapid formation of products.

Thus, we can conclude that statement the reaction is completed in a shorter amount of time, best describes the result of using a catalyst in a chemical reaction.

Each energy sublevel contains __________ number of electrons. For example, sublevel D can hold up to _______ electrons. A. the s
Annette [7]

Answer:

Each energy sublevel contains a different number of electrons. For example, sublevel D can contain up to 10 electrons

Explanation:

The atoms are surrounded by propellers that within each propeller there is a certain number of electrons, these electrons jump from orbit to orbit according to the amount of energy they have. The four levels that make up the electronic cloud that surrounds an atom are: s p d f.

When these electrons change orbit or level they release energy in the form of light, which is known as a photon.

Predict how the addition of a catalyst would affect the rate of the reaction below, and explain your prediction H2 (g) + I2 (g)
Fynjy0 [20]
A catalyst is a chemical substance that hastens the chemical reaction. This does not participates in the creating the product(s) but allows it to be formed easily. With this, it is now known that the rate of the reaction becomes relatively higher compared to the uncatalyzed reactions.

Therefore, the answer to this item is the rate of the reaction becomes faster.

What does the constant bombardment of gas molecules against the inside walls of a container produce?
alukav5142 [94]
<span>The constant bombardment of gas molecules against the inside walls of a container produces Pressure.

Explanation:
                    Pressure is defined as Force per unit Area.

                                        P  =  F  /  A

In case of gases, the gas molecules have high Kinetic Energy and they move with high velocity. This cause them to strike against the inside wall of the container. Pressure is directly proportional to temperature. Increase in temperature cause to increase the Kinetic Energy of molecules, Hence, the rate of collisions increases resulting in increasing the pressure.</span>
