Task 2: Chemical Reactions in the Environment
Goal: Classify chemical reactions as one of the following types: combustion, synthesis,
decomposition, single replacement, and double replacement.
Directions:
Read each scenario describing chemical reactions related to acid rain pollution in the environment.
As you read, answer the accompanying questions. You will need to reference your notes from Task 1
as you work.
What is acid rain?
Acid precipitation is rain, snow, fog, or dew that has a pH of less than 5.6. Click on this article to
read about it.
1.
According to the article, what causes acid precipitation?
When Sulfur dioxide and nitrogen oxides are emitted into the atmosphere and transported by wind
and air currents.
Coal and oil contain sulfur and when burned in factories and power plants, the sulfur combines with
oxygen in the air and is emitted into the atmosphere. The gas then undergoes chemical reactions in
the atmosphere that result in the formation of acids, which eventually fall as acid precipitation. Sulfur
dioxide is converted to sulphuric acid by two chemical reactions.

2.
What type of chemical reactions are these? How do you know?
Sulfuric acid can dissociate into sulfate ions and hydrogen ions which lowers the pH causing acidic
environments that are very harmful to many ecosystems.
