Concept explainers
Interpretation:
The number of marble statues damaged by acid rain is to be calculated and the other undesirable product of acid rain damage is to be determined.
Concept Introduction:
Acid rain is the rain full of acids, which causes environmental pollution. It is very harmful to plants, the soil, insects, bacteria, and also to aquatic life. It results in the corrosion of steel and also has a bad impact on human health.
Global warming is caused by any long-term increase in the temperature of the earth. It is very harmful for the environment and also causes problems to plants and animals.
Answer to Problem 73AP
Solution:
(a)
The total number of statues destroyed by acid rain is
(b)
The undesirable product is carbon dioxide, which causes global warming.
Explanation of Solution
a) The number of 100 lb marble statues the resulting rain can damage.
Sulfur dioxide released is
20% of sulfur dioxide is converted into sulfuric acid.
The marble statue is of
Acid rain is caused by the emission of sulfur dioxide and nitrogen dioxide in the air. When sulphur dioxide is released into the atmosphere, sulfuric acid is produced. This causes acid rain and damages marble statues.
The reaction which causes acid rain is as follows:
The sulfuric acid produced reacts with the marble that consists of calcium carbonate
The reaction is as follows:
Conversion of a mass of sulfur dioxide
Therefore, the moles in sulfur dioxide are
Conversion of
Sulfur dioxide into moles of sulfuric acid is as follows:
Therefore, the moles in sulfuric acid are
The moles in calcium carbonate that destroy
Therefore, the moles in calcium carbonate per statue are
Number of statues destroyed by
Thus, the number of statues damaged by acid rain is
b) Other undesirable result of the acid rain damage
Acid rain caused by sulfuric acid in statues produces carbon dioxide as an undesirable product, which supports global warming.
Global warming is mainly caused by the emission of carbon dioxide and chlorofluorocarbons. It has many adverse effects on climate change, human health, and plants.

In the year 2000, this chemical reached its peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere.
