H₂SO₃ is weaker acid than H₂SO₄.
The bonding power of an acid is typically influenced by the size of the "SO₄" atom; the smaller the "SO₄" atom, the stronger the H-A bond. The atoms get larger and the bonds get weaker as you proceed down a row in the Periodic Table, strengthening the acids.
<h3>Describe acid.</h3>
The term "acid" refers to any molecule or ion that can donate a proton (a Brnsted-Lowry acid) or establish a covalent bond with an electron pair (a Lewis acid). The first class of acids is the proton donors, also known as Brnsted-Lowry acids.
Its chemical name is lysergic acid diethylamide, or LSD as it is more often known. Because it has a potent hallucinogenic impact, using it could alter how you see the world and its objects. The effects of LSD are referred to as tripping.
The term "acid" is frequently used to denote aqueous solutions of acids with a pH lower than 8, even though the technical meaning of the term only pertains to the solute.

Solution :
<u>Explanation 1 </u>:
Spontaneity of the reaction is based on two factors :
-- the tendency to acquire a state of minimum energy
-- the energy of a system to acquire a maximum randomness.
Now, since there isn't much difference in the bond enthalpies of B-F and B-Cl. So, we can say the major driving factor is tendency to acquire a state of maximum randomness.
<u>Explanation 2 </u>:
A system containing the 
B halides has a 
than a system of 
and 
.
It has the same number of 
, but more distinguishable kinds of 
, hence, more microstates and higher entropy.

<span>An atom's identity, that is, whether it is 'oxygen' or 'plutonium', for example, is determined solely by the number of protons in the nucleus. The number of neutrons also plays a part - a differing number of neutrons can change an atom from one isotope of an element into another, but the atoms would still remain the same element, albeit a different isotope. The number of electrons orbiting the atom does not change the identity of the atom, only it's electronic state. Take electrons away and it becomes a positively charged ion of the same element. Add electrons and it becomes a negatively charged ion, but still of the same element.</span>
I personally, would remove " Lamp oil is a very polar substance " And replace it with what the article you wrote, was about. For example, lets say you wrote about why people love ice cream, you could have the ending sentence say. " And that's why I wrote about why people love ice cream" Or something along those lines. I'd write a few more facts about it first, don't just have one sentence saying a fact without any supporting detail, hope this helps! :)
