Question

Rain water is naturally acidic due to the formation of carbonic acid from dissolved carbon dioxide (CO2). Atmospheric sulfur oxides, produced when coal is burned for fuel, can cause rain water to become even more acidic. In some locations, pH values below five have been measured. Results of the increasing acidity include increased ocean acidifcation, slowed coral growth, and damage to marble statues. Balance the following equations related to the acidification of rain by inserting coefficients as needed. If already balanced, leave the equation as-is.

Explanation / Answer

Ans 1 :

Start balancing the reactions by observing and carefully noting down the atoms on each side.

Then balance the atoms on each side.

The balanced reactions are given as :

S + O2 = SO2

2SO2 + O2 = 2SO3
