The O2 molecule breaks apart at lower wavelengths than the O3 molecule. What is the main reason for this?
kozerog [31]

The main reason for this is Average bond of O₂ is shorter and strong from O₃.

<h3>What is ozone?</h3>

Ozone is a blue gas composed of three oxygen atoms bonded together.

It occurs naturally high up in the Earth's atmosphere, where it protects the surface from harmful ultraviolet (UV) rays,

UV radiation will dissociate ozone into an oxygen atom and an oxygen molecule.

Ozone molecules are tetrahedral so the bond angle is  109 degree the electrons in the double bond occupy more space that the non-bonding electron pair.

Oxygen has a small size that leads to smaller O-O bond length.

A lone pair of electrons on both the oxygen repel each other leading to weakening of O-O bond.

O3 has longer and weaker bonds than O2, whereas SO2 has shorter and stronger bonds than SO.

Molecular oxygen, O2, is photolyzed by light of 241 nm and has a bond energy of 498 kJ/mol.

The main reason for this is Average bond of O₂ is shorter and strong from O₃.

1) Sodium chloride undergoes an electrolysis reaction producing two new substances. One is a metal and the other is a gaseous el
Lena [83]

Metallic sodium and chlorine gas are produced by the electrolysis of molten sodium chloride.

<h3>What is a word equation?</h3>

A word equation represents a chemical reaction using the names of the substances involved.

a) Word equation:

Sodium chloride + electrolysis →  Sodium hydroxide + Hydrogen gas, Chlorine gas

b) The following reactions take place during the electrolysis of brine solution :

NaCl =Na^+ +Cl^-

H_2O =H^+ +OH^-

Now there are two cations and two anions which get discharged in the following way :

At cathode : 2H^+ +2e^- = H_2

At anode: 2Cl^- - 2e-=Cl_2

The remaining ions

Na^+ +OH- = NaOH

That's why we get H_2, Cl_2 and NaOH.

c) Balance each equation is:

2NaCl (l)  →   2Na(s) + Cl_2(g)
