What emissions lead to acid rain?
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.
Which chemical in the emissions standard contributes to acid rain?
sulfur dioxide
Acid rain is caused by industrial emissions of sulfur dioxide and nitrogen oxides (which form much stronger acids when equilibrated in rainwater).
How is combustion related to acid rain?
When coal is burned the sulfur combines with oxygen and the sulfur oxides are released to the atmosphere. This reacts with water molecules in the atmosphere to form sulfuric acid, a strong mineral acid. This makes rain acidic.
Does no2 contribute to acid rain?
NO2 and other NOx interact with water, oxygen and other chemicals in the atmosphere to form acid rain. Acid rain harms sensitive ecosystems such as lakes and forests.
What type of chemical reaction is acid rain?
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
Does NO2 cause acid rain?
Which gases do not cause acid rain?
Carbon dioxide reacts with water to form carbonic acid thus contributing to acid rain. So, from all these gases only carbon monoxide does not react with water to form an acid. Thus, not contributing to the acid rain, So, the correct answer is “Option C”.
What are the main causes of acid rain?
Human emissions. The principal cause of acid rain is sulfur and nitrogen compounds from human sources, such as electricity generation and motor vehicles. The gases can be carried hundreds of miles in the atmosphere before they are converted to acids and deposited.
The SO 2 and NO X react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground. While a small portion of the SO 2 and NO X that cause acid rain is from natural sources such as volcanoes, most of it comes from the burning of fossil fuels.
What happens when carbon dioxide reacts with water?
Carbon dioxide reacts with water to form carbonic acid (Equation 1). Carbonic acid then dissociates to give the hydrogen ion (H +) and the hydrogen carbonate ion (HCO 3 -) (Equation 2). The ability of H 2CO 3 to deliver H + is what classifies this molecule as an acid, thus lowering the pH of a solution.
What happens when calcium carbonate is dissolved in acid rain?
A chemical reaction (Equation 9) between calcium carbonate and sulfuric acid (the primary acid component of acid rain) results in the dissolution of CaCO3 to give aqueous ions, which in turn are washed away in the water flow.
