Ulfur dioxide gas can react in the presence of oxygen and vanadium(V) oxide to form sulfur trioxide. Sulfur trioxide is the only
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.

olasank [31]

The electronic configuration of x, y, and z.

x=1s^2

Y= 1s^22s^22p^63s^2

Z= 1s^22s^22p^63s^23p^5

<h3>What is an electronic configuration?</h3>

Electronic configuration, also called electronic structure, is the arrangement of electrons in energy levels around an atomic nucleus.

a.

x=1s^2

Y= 1s^22s^22p^63s^2

Z= 1s^22s^22p^63s^23p^5

b.

x= Period 1 and group18

Y=Element is in period 3 and Group 2

Z=Element is in period 3 and group 17.

c.

X, Y & Z represents Helium, magnesium, and chlorine.

when performing solubility studies, why you should use deionized or distilled water rather than tap water?
Cerrena [4.2K]

Answer:

The science project or the proposed test using the water as a control element in the experiment determines whether you choose to use deionized water or distilled water. Of the two, distilled water is the purest because the water undergoes boiling that kills off most organic contaminants.

The ionization energies for removing successive electrons from sodium are 496 kJ/mol, 4562 kJ/mol,
ddd [48]

Answer:

D

Explanation:

The high jump of ionization energy indicates that we are trying to remove electron from noble gas configuration state.

The ionization energy data specifies that the Elements are from group 1 at period 3 or greater.

Removing the first electron require 496 kJ and the second ionization energy jump significantly due to the removal of electron from the noble gas configuration which is logical because electron try to maintain the especially stable state.
