Answer:

The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
Step-by-step explanation:
The given expression is 
We factor the left hand side to get:

We divide both sides by: a-b

Observe that the difference of a and b is in the denominator.
The whole is of the form: 
The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
To make this anion into a complete acid, then this must
be added with Hydrogen ion H+. So the chemical equation looks like:
H+ + SO3(2-)
--> ?
Now to balance it:
H+ + SO3(2-)
--> H2SO3
Answer:
H2SO3
1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
