Chemistry of the Environment Flashcard

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). They contribute to the greenhouse effect and climate change.

Front

How do trees help combat climate change?

Back

Trees absorb carbon dioxide during photosynthesis, reducing the amount of CO2 in the atmosphere and helping to mitigate climate change.

Front

What is acid rain?

Back

Acid rain is precipitation that contains high levels of sulfuric and nitric acids, resulting from the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.

Front

What are catalytic converters?

Back

Catalytic converters are devices in vehicles that convert harmful gases like carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful emissions before they exit the exhaust system.

Front

What is flue gas desulfurization?

Back

Flue gas desulfurization is a process used to remove sulfur dioxide from the exhaust flue gases of fossil-fuel power plants, helping to reduce acid rain.

Front

How can low-sulfur fuels help reduce acid rain?

Back

Using low-sulfur fuels decreases the amount of sulfur dioxide released into the atmosphere, thereby reducing the formation of acid rain.

Front

What is the role of anhydrous cobalt(II) chloride in water testing?

Back

Anhydrous cobalt(II) chloride changes color from blue to pink when it comes into contact with water, indicating the presence of moisture.

Front

What is the role of anhydrous copper(II) sulfate in water testing?

Back

Anhydrous copper(II) sulfate turns from white to blue when it absorbs water, indicating the presence of moisture.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.
