Sulfur dioxide from coal-fired power plants combines with water in the atmosphere to produce acid rain. What is the product when one molecule of SO2 reacts with one molecule of watera. two sulfite ions
b. one molecule of sulfuric acid
c. two molecules of sulfurous acid
d. one sulfate ion
e. one molecule of sulfurous acid

e. one molecule of sulfurous acid

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The equation when when one molecule of SO2 reacts with one molecule of water is:

Thus the product formed is one molecule of sulphurous acid.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
