Gas Emissions Analysis: Impact on Global Environment
How many metric tons (t) of each gas are emitted per year from the Hawaiian volcano Kilauea?
A. 547.5 tons of gasses are released per year.
Analysis of Gas Emissions from Kilauea Volcano
When corrected to 298 K and 1.00 atm, the Hawaiian volcano Kilauea emits an average of 1.5X10³ m³ of gas each day. The mixture contains various gases contributing to global warming, acid rain, and toxicity.
The atmospheric chemist's analysis of a gas sample from Kilauea reveals the following mole fractions:
- CO₂: 0.4896
- CO: 0.0146
- H₂O: 0.3710
- SO₂: 0.1185
- S₂: 0.0003
- H₂: 0.0047
- HCl: 0.0008
- H₂S: 0.0003
To calculate the metric tons of each gas emitted per year, we use the given value of 547.5 tons released annually.
Gas Emissions Calculation and Impact
Given the daily gas emissions of 1.5X10³ m³ from Kilauea, we can calculate the yearly emissions:
(1.5 * 365 * 1000) / 1000 = 547.5 tons
Therefore, 547.5 metric tons of gases are released from the volcano annually.
The analysis of mole fractions provides insights into the composition of the emitted gases. The high fraction of carbon dioxide (CO₂) and water vapor (H₂O) indicates significant contributions to global warming. Sulfur dioxide (SO₂) and hydrogen sulfide (H₂S) are known for their role in acid rain formation, while carbon monoxide (CO) poses toxicity risks.
It is crucial to monitor and regulate gas emissions from volcanic activities to mitigate their impact on the environment and human health. Understanding the composition and quantities of gases released allows scientists to implement strategies for reducing harmful effects on the atmosphere.
